In terms of the project’s status, Metrolinx is currently concluding the Pre-Planning Phase. This will be followed by the issuance of a Notice of Commencement, finalization of the E.P.R. Addendum and the issuance of a Notice of Completion. Once the Notice of Completion is issued, the finalized E.P.R. Addendum will be made available for 30 days for review by the public (including property owners), Indigenous Communities, review agencies and other stakeholders.

5.2 Overview of the Draft Environmental Project Report Addendum

The following is a high level overview of the relevant information found in the Draft E.P.R. Addendum concerning Metrolinx’s GO Rail Network Electrification Project, including information related to the work being proposed within the limits of the City of Oshawa.

Context

The GO Rail Network Electrification T.P.A.P. is part of the Metrolinx On-Corridor Program (“OnCorr”), which is the largest capital project within the GO Expansion Program for the Greater Toronto and Hamilton Area (“G.T.H.A.”).

Metrolinx is expanding its services as part of the GO Expansion Program in terms of both train frequency and availability. The purpose of the GO Expansion Program is to transform the GO Rail Network into a comprehensive regional rapid transit network system that provides the expanded mobility the G.T.H.A. needs to accommodate growth and maintain a high quality of life and prosperous economy.

Metrolinx’s long-term objective for the program is to provide 15-minute, two-way, all-day rail service. Metrolinx plans to quadruple service and double ridership through this program. Additionally, Metrolinx plans to provide electrified service along several rail corridors.

The purpose of the GO Rail Network Electrification T.P.A.P. is to assess and provide appropriate mitigation measures for additional electrification infrastructure required for new/upgraded tracks and layover facilities proposed as part of a separate Metrolinx study called the New Track and Facilities T.P.A.P. Staff comments on the draft E.P.R. for the New Track and Facilities T.P.A.P. were endorsed by Oshawa City Council on June 22, 2020 pursuant to Report DS-20-60 dated June 3, 2020 and forwarded to Metrolinx, the Region of Durham and the Central Lake Ontario Conservation Authority.

67 Report to Development Services Committee Item: DS-20-99 Meeting Date: September 14, 2020 Page 4

The original assessment of electrification infrastructure previously evaluated as part of the 2017 Electrification E.P.R. did not include the assessment of new infrastructure being proposed in the New Track and Facilities T.P.A.P., which includes the following:

. New tracks within existing Metrolinx rail rights-of-way; . Modifications or upgrades to existing tracks within existing Metrolinx rail rights-of-way; . Three (3) new layover/storage facilities; . New GO Station platforms; . Bridge expansion/modifications; and, . Electrification of a portion of the Richmond Hill GO Rail Corridor.

All changes owing to the New Track and Facilities T.P.A.P. that are inconsistent with the approved 2017 Electrification E.P.R. require a reassessment. Accordingly, the Draft E.P.R. Addendum for the GO Rail Network Electrification Project involves an evaluation of the following matters:

. The effects associated with the project; . The identification of potentially new mitigation measures; and, . Potentially, new monitoring systems.

Metrolinx has determined that the resulting changes to the electrification project are “significant”. Consequently, the publication of a Notice of Environmental Project Report Addendum and a 30-day comment period is required under Ontario Regulation 231/08.

The following are the key steps identified by Metrolinx in the Pre-Planning Phase of the E.P.R. Addendum process:

. Prepare an assessment of the effects the proposed changes may have on the environment; . Prepare and distribute an E.P.R. Addendum; . Prepare and distribute a Notice of E.P.R. Addendum; and, . Conduct a final review with input from the public and stakeholders prior to proceeding with the proposed Addendum.

In addition to the steps listed above, Metrolinx has also voluntarily included opportunities for additional consultation in the form of three (3) rounds of public meetings (two of which have taken place to date), generally consistent with the consultation which would be completed for a new T.P.A.P.

Following completion of the Pre-Planning Phase, a Notice of Commencement will be issued to initiate the T.P.A.P. Phase, which will involve the following activities:

. Issuance of the Notice of Commencement; . Public Consultation; . Meetings with stakeholders (e.g., Review Agencies, Municipalities, Indigenous communities, Utility companies); . Public Meeting Round 3; . Finalization of the E.P.R. Addendum; and, . Issuance of the Notice of Completion (within 120-days of Notice of Commencement).

68 Report to Development Services Committee Item: DS-20-99 Meeting Date: September 14, 2020 Page 5

Once the Notice of Completion is issued, the finalized E.P.R. Addendum will be made available for 30 days for review by the public (including property owners), Indigenous Communities, review agencies and other stakeholders.

Following the 30-day review period, the Minister has 35 days to issue one of following three notices:

. Proceed with the Project in accordance with the E.P.R. Addendum; . Proceed with the Project in accordance with the E.P.R. Addendum subject to conditions; or, . Require the proponent to conduct further work and submit a revised E.P.R. Addendum.

Project Scope

As part of the GO Expansion Program, Metrolinx has identified six (6) rail corridors to convert from diesel to electric propulsion:

. Lakeshore East; . Lakeshore West; . Kitchener; . Barrie; . Stouffville; and, . Richmond Hill.

The majority of the infrastructure required for the electrification of these corridors was previously examined as part of the 2017 Electrification E.P.R. The Draft E.P.R. Addendum assesses additional electrification infrastructure required for new/upgraded tracks and layover facilities which are being studied as part of a separate Metrolinx study called the New Track and Facilities T.P.A.P. As noted in Section 5.2.1 of this Report, City comments on the Draft E.P.R. for the New Track and Facilities T.P.A.P. were previously provided to Metrolinx pursuant to Report DS-20-60 dated June 3, 2020.

For the Lakeshore East corridor, which currently terminates at the existing Oshawa GO Station on Bloor Street West, the following was proposed under the New Track and Facilities T.P.A.P.:

. 3.28 kilometers (2.04 mi.) of new track parallel to existing sections of the mainline; . 23 new switches; . A new platform at the existing Oshawa GO Station; and, . Expansion of the Thickson Road Bridge in Whitby.

Electrification of this new infrastructure along the Lakeshore East corridor is proposed through the subject Draft E.P.R. Addendum.

69 Report to Development Services Committee Item: DS-20-99 Meeting Date: September 14, 2020 Page 6

Project Description

The following elements are listed in the project description as being included in the electrification of GO rail corridors in general:

Overhead Contact System (O.C.S.):

. The O.C.S. is the fundamental component of the traction power distribution system and generally includes the following components:

- O.C.S. pole foundations; - Portal/cantilever poles; and, - Contact, autotransformer, and feeder wires. . The O.C.S. consists of a wiring system that provides efficient transfer of traction power to the train.

. The O.C.S. will be suspended from several steel support structures planned along the corridors, including on bridges and overpasses where required.

. For Metrolinx’s purposes in assessing potential impacts, a conservative “O.C.S. Impact Zone” was established that includes the area of the tracks to be electrified, plus a five (5) metre (16.4 ft.) buffer from the centerline of the outermost track to be electrified on either side of the rail corridor.

Vegetation Clearing Zone:

. A Vegetation Clearing Zone is required in order to provide safe electrical clearances to any existing vegetation along the rail corridor.

. The Vegetation Clearing Zone entails vegetation removal within the area encompassed by the O.C.S. infrastructure and associated O.C.S. Impact Zone, plus an additional two (2) metre (6.6 ft.) buffer, resulting in a total clearing area of seven (7) metres (23.0 ft.) measured from the centerline of the outermost tracks to be electrified on either side of the rail corridor.

Based on the elements above, the following is worthwhile noting with respect to the effects of the new infrastructure identified in the New Track and Facilities T.P.A.P. for the Oshawa GO Station (see Attachment 2):

. For the new third track from Mile 10.44 to 11.76, a portion of the Vegetation Clearing Zone for the new infrastructure falls outside the 2017 Electrification E.P.R. Environmental Assessment (E.A.) study area;

. The new platform and retaining wall at the existing Oshawa GO Station is outside the 2017 Electrification E.P.R. Scope, and will be addressed in the New Track and Facilities T.P.A.P.; and,

. The new track on the north side of the new island platform, from Mile 11.56 to 11.74, falls outside the 2017 Electrification E.P.R. E.A. study area in its entirety.

70 Report to Development Services Committee Item: DS-20-99 Meeting Date: September 14, 2020 Page 7

Baseline Conditions

The Draft E.P.R. Addendum includes a study of baseline conditions in order to establish a snapshot of existing conditions within the study areas prior to any improvements taking place. This study forms the basis of the assessment of all potential impacts.

An assessment of baseline conditions was completed by Metrolinx for the following areas of study:

. Natural Environment Assessment; . Preliminary Environmental Site Assessment; . Cultural Heritage Assessment; . Archaeological Baseline Conditions; . Land Use and Socio-Economic Assessment; . Air Quality; . Noise and Vibration; . Visual Assessment; . Utilities; . Stormwater Management; . Groundwater and Wells; . Hydrogeology Assessment; and, . Electromagnetic Interference/Electromagnetic Fields (E.M.I./E.M.F.) Impact Assessment.

The baseline conditions review describes the Lakeshore East corridor as being located within a mixed urban and rural setting, extending from the eastern portion of the City of Toronto, through Pickering, Ajax and Whitby, and terminating in the City of Oshawa.

Specific to the portion of the Lakeshore East corridor within Oshawa, there are no trails, large parks or other recreational amenities along this segment of the rail corridor. There are also no hospitals, schools, places of worship, child-care centres or long-term care centres in the vicinity of the rail corridor. No Cultural Heritage Resources were identified within 30 metres (98 ft.) of this segment of the rail corridor.

In terms of potential for archaeological resources, the segment of the Lakeshore East corridor within Oshawa includes four previously registered archaeological sites within one (1) kilometre (0.621 mi.) of the Oshawa corridor segment. However, none of these are located within 50 metres (164 ft.) of the proposed infrastructure at the Oshawa GO Station. The Draft E.P.R. Addendum identifies that “these criteria are indicative of the study area as having potential for the identification of Indigenous and Euro-Canadian archaeological resources, depending on soil conditions and the degree to which soils have been subject to deep disturbance.”

Negligible visual effects on the existing views are expected as the surrounding area consists of industrial/employment lands where views already feature exposure to the existing Oshawa GO Station and train storage area.

71 Report to Development Services Committee Item: DS-20-99 Meeting Date: September 14, 2020 Page 8

Concerning the potential effects on utilities, Metrolinx is currently in the process of completing a due diligence exercise which will review new track/upgrade areas to determine any utility conflicts.

Concerning Electromagnetic Interference (E.M.I.), no E.M.I. sensitive sites were identified between 100 metres (328 ft.) and 250 metres (820 ft.) from the Lakeshore East Corridor, which is considered by Metrolinx to represent a “conservative evaluation zone”.

Concerning Electromagnetic Fields (E.M.F.), measurements undertaken at select points along the Lakeshore East Corridor as part of the 2017 Electrification E.P.R. revealed that there were no areas of concern along this corridor. Consequently, there are no locations where post-electrification measurement of Extremely Low Frequencies (E.L.F.) was recommended.

Concerning stormwater management, Metrolinx has stated that quantity and drainage patterns are not anticipated to be affected as a result of the electrification infrastructure proposed, based on the preliminary analysis undertaken as part of the conceptual design work.

Metrolinx is currently undertaking the following studies as part of preparing the Draft E.P.R. Addendum:

. Amended Noise/Vibration Modelling and Impact Assessment Report; and, . Amended Air Quality Modelling and Impact Assessment Report.

The results of these studies will be published by Metrolinx once available and as appropriate.

Impact Assessment

Potential effects were assessed and mitigation measures developed based on the following four step approach:

1. Identify potential effects (positive and negative) resulting from the construction and/or operation of the project infrastructure;

2. Establish avoidance/mitigation/compensation measures to eliminate or minimize potential negative effects (as required);

3. Carry out consultation with stakeholders/regulatory authorities and update impact assessment results and/or proposed avoidance/mitigation/compensation mitigation measures as appropriate; and,

4. Document impact assessment results.

72 Report to Development Services Committee Item: DS-20-99 Meeting Date: September 14, 2020 Page 9

For the purposes of differentiating the various types of potential environmental effects related to the project, effects were characterized and grouped as outlined below:

. Footprint Impacts - Potential displacement or loss of existing environmental features within the Study Area due to implementation of the physical Electrification Project components/infrastructure.

. Operations and Maintenance Impacts - Potential long-term effects due to operations and/or maintenance activities associated with the electrified GO Transit network.

. Construction Impacts - Potential short-term effects (e.g., disruption/disturbance) on existing features due to construction activities associated with the Electrification Project.

Specific to the segment of the Lakeshore East corridor within Oshawa, the potential effects and mitigation measures were described as follows:

. Natural Environment – There will be a minor impact on 0.9 hectares (2.2 ac.) of cultural meadow north of the rail corridor, south of 933 Bloor Street West in Oshawa and 2001 and 2009 Victoria Street East in Whitby. A 0.4 hectare (1.0 ac.) portion of the cultural meadow is located within Oshawa. Mitigation measures related to vegetation clearing consist of vegetation management as per Metrolinx’s Vegetation Guideline (2020), which outlines the following mitigation measures:

- Detailed Tree Inventory: All trees which are 10 centimetres (3.9 in.) or greater in diameter within the study area or with canopies or Tree Protection Zone (T.P.Z.) extending into the study area are to be inventoried. Species at Risk (S.A.R.) that may be directly impacted by the tree removal shall be identified during the tree inventory to the extent possible using tree inventory methods. This includes identification of S.A.R. such as Butternut as well as information on the potential suitable habitat for S.A.R., such as the presence of bat cavity trees, where visible.

- Tree Protection: Detailed measures are to be implemented to protect retained adjacent trees. These will include the identification of T.P.Z. limits, diagrams of tree protection barrier types, tree protection measures, and the identification of construction storage and staging areas where information is available.

- Vegetation Compensation: Metrolinx has established a vegetation compensation approach for determining and implementing compensation for the removal of trees from the Metrolinx right-of-way (R.O.W.) as well as public and private lands. It is a landscape science-based approach designed to reflect the basic principles of the Toronto and Region Conservation Authority’s (T.R.C.A.) ecosystem-based approach in addition to following the requirements of applicable by-laws and regulations. Compensation will follow one or a combination of the following approaches: ecological, baseline, or by-law.

- For Trees within Metrolinx Property: All trees within the Metrolinx R.O.W. will be compensated for using either an ecological or baseline approach. Where tree removals are located within a designated natural area, ecological compensation will

73 Report to Development Services Committee Item: DS-20-99 Meeting Date: September 14, 2020 Page 10

be implemented. Where removals are outside a designated natural area, a 1:1 ratio approach will be implemented (baseline compensation).

- For Public/Private Trees: Compensation for trees within public and private lands, including those on the boundary between the Metrolinx R.O.W. and public or private lands, will follow with the requirements of applicable by-laws and regulations. Trees on public or private lands that are not subject to by-laws/regulations will be compensated for following an ecological or baseline approach. Metrolinx will work directly with residents to address the loss of trees on private property.

. Corbett Creek Tributary – A tributary of Corbett Creek is located north and south of the Metrolinx R.O.W., with the tributary crossing beneath the tracks in Whitby near the existing Oshawa GO Station. However, railway infrastructure already exists and crosses this tributary and therefore the additional footprint infrastructure is not expected to further impact the tributary. To mitigate the potential indirect impacts to the watercourses, Metrolinx has advised that sediment and erosion controls will be implemented and precautions taken to prevent spills and the release of hazardous materials.

. Archaeology – A Stage 2 Archaeological Assessment conducted by test pit survey at five (5) metre (16.4 ft.) intervals will be conducted by a professionally licensed archaeologist prior to disturbance.

. Land Use and Socio-Economic Impacts – The additional O.C.S. infrastructure area is anticipated to extend beyond the limits of the existing rail R.O.W. in this segment. Consequently, private property acquisition will be required to accommodate this infrastructure. As a result of this activity, there is a footprint impact on the adjacent employment/ industrial land uses. However, most of the footprint impacts fall within Metrolinx-owned property surrounding the existing Oshawa GO Station.

. Municipal Approvals – Although Metrolinx is not subject to municipal permits and approvals, Metrolinx’s policy is to adhere to the intent of the relevant permits/approvals requirements to the extent possible. Additional coordination (which may include a series of meetings, discussions, and agreements) with the City of Oshawa will be undertaken during the detailed design process to finalize design details and minimize any impacts on adjacent uses.

. Zoning – City staff note that the existing Oshawa GO Station and associated tracks are currently zoned SI-C/EU (Select Industrial/Existing Use) and GI (General Industrial) under Zoning By-law 60-94. However, Section 5.4.1 of the City’s Zoning By-law states that “none of the provisions of this By-law shall apply to prevent the use of any land or the erection or use of any building or structure, or part thereof, by a public authority.” Metrolinx is considered to be a public authority in accordance with the associated definition contained in Zoning By-law 60-94.

. Visual Impacts – Negligible impacts to the existing views are expected as the new O.C.S. infrastructure is almost entirely within the existing rail corridor R.O.W., and the surrounding area consists of industrial/employment lands where views already feature exposure to the existing Oshawa GO Station and train storage area.

74 Report to Development Services Committee Item: DS-20-99 Meeting Date: September 14, 2020 Page 11

. Electro-Magnetic Impacts – Metrolinx notes that the potential effects due to operating an electrified transit system are largely the result of overhead catenary wires to power the train, and the operation of 25 kilovolt aerial feeder lines to power the catenary. Mitigation for each of these potential effects has been implemented in the design of the system by Metrolinx, including the following:

- The power methodology for the system—autotransformer power—was selected specifically for its reduction of E.M.I. interference;

- The implementation and use of an Electromagnetic Compatibility (E.M.C.) Control Plan;

- The application of proper design, e.g., grounding and shielding as per applicable Canadian electrical standards and physical separation as identified from bench- marking similar properties across North America;

- Field testing and verification of overall E.L.F. and radio frequency emissions emanating from the GO electrified railway system as a whole during the electrification commissioning phase to ensure E.M.F.s are within the limits of applicable industry standards; and,

- Verification of E.L.F./E.M.F. by measurements taken before and after project implementation.

Operations and Maintenance Impacts

The Draft E.P.R. Addendum identified anticipated ongoing operations effects and maintenance activities associated with the implementation of the GO Rail Network Electrification T.P.A.P.

The potential noise impacts of trains and associated equipment and facilities are assessed in all corridors and corridor segments, including assessing activities such as running or idling of GO trains along corridors, at stations and in layover or train storage facilities.

Where facilities or residential areas are close to the additional O.C.S. infrastructure area, there is the potential for visual effects and/or noise effects. Metrolinx completed a Visual Impact Assessment and Noise Impact Assessment to identify areas where the O.C.S. may affect views of the corridor or where noise levels may increase. There were no sensitive facilities identified in the vicinity of the Lakeshore East rail corridor R.O.W. which would require mitigation for visual and/or noise effects.

Construction Phase Impacts

The Draft E.P.R. Addendum provides anticipated construction phase impacts and proposed mitigation measures associated with the Project.

Construction activities and associated impacts are generally temporary, short-term and localized in nature. Construction Management Plans will be developed and implemented during the detailed design phase and implemented as part of construction. Construction

75 Report to Development Services Committee Item: DS-20-99 Meeting Date: September 14, 2020 Page 12 staging area locations will also be identified during the detailed design phase. Metrolinx (or their contractor) will coordinate with municipalities and road authorities, as appropriate, during the detailed design phase to develop traffic, parking, transit, cycling and pedestrian management strategies prior to commencement of construction. This will facilitate the avoidance or minimization of interference to transportation to the extent possible during construction.

Potential impacts to the natural environment are anticipated to be minimal during construction as the majority of new tracks and switches are proposed within the existing rail corridor R.O.W. During the installation of the O.C.S., vegetation removals will be required. A Vegetation Management Plan will be prepared as part of the detailed design work.

Sedimentation and erosion may result from vegetation clearing and excavations for O.C.S. foundations. An Erosion and Sediment Control Plan will be prepared prior to and implemented during construction to minimize the effects of sedimentation and erosion on natural features.

Public and Stakeholder Consultation

At the outset of the Pre-Planning Phase of the GO Rail Network Electrification T.P.A.P., a Stakeholder Consultation Plan was developed by Metrolinx which outlined a strategy and approach for consulting with stakeholders throughout the course of the T.P.A.P. The objectives for the consultation strategy remained the same as those from the 2017 Electrification E.P.R.

In an effort to engage a diverse set of participants, provide information and updates on the project and allow interested persons to provide comments and feedback throughout the process, the following consultation tools were used by Metrolinx:

. Online via Metrolinx Engage;

. Project email addresses;

. Public open houses and public review opportunities;

. Newspaper and radio advertisements;

. Notifications and email updates, including to property owners and Indigenous Communities; and,

. Meetings with review agencies (provincial, municipal and conservation authorities), elected officials, and other stakeholders (e.g., transit authorities, utilities).

Consultation commenced on January 31, 2020 with the publication of the initial Notice of Public Open House.

The nearest public open house to Oshawa was held in the Town of Whitby on February 29, 2020, from 11:30 a.m. to 1:30 p.m. at the Abilities Centre (55 Gordon Street).

76 Report to Development Services Committee Item: DS-20-99 Meeting Date: September 14, 2020 Page 13

There were approximately 120 attendees and 24 comment forms submitted to Metrolinx. Common questions, comments, and concerns about the GO Expansion Program included:

. Support for the planned service increases and infrastructure improvements; . Anticipated timeline for electrification and the type of future rail fleet; and, . Timelines for other Metrolinx planned and proposed projects.

It is unknown how many of the attendees are Oshawa residents or if any of the submitted comments can be attributed to them.

Commitments and Future Work

The Draft E.P.R. Addendum lists the proposed commitments and work to be carried out during future project phases (e.g., detailed design, construction), and outlines the anticipated approvals and permits required.

To ensure that potential adverse environmental effects associated with the GO Rail Network Electrification T.P.A.P. are avoided/minimized/mitigated to the extent possible, the following action will be taken by Metrolinx during the detailed design and construction phases of the project:

. Implementation of all mitigation and monitoring measures documented in the E.P.R. Addendum during detailed design, construction and operational phases;

. Ensuring that all mitigation and monitoring measures and commitments outlined in the E.P.R. Addendum are included in the contract documents for implementation by Metrolinx, Hydro One and/or its contractors; and,

. Undertaking all additional studies/work outlined in the E.P.R. Addendum and/or the 2017 Electrification E.P.R. prior to implementation of the project, including the establishment of an Environmental Management System (E.M.S.) to ensure that environmental protection/mitigation measures identified through the T.P.A.P. are fulfilled and functioning as expected.

In addition to carrying out the T.P.A.P. and satisfying the requirements of the Environmental Assessment Act, there are a number of other federal, provincial, municipal, and other approvals/permits that will be required for the project in order to implement it, such as municipal building permits.

With respect to obtaining municipal permits/approvals, provincial agencies such as Metrolinx are not subject to requirements to obtain municipal permits and approvals. However, it is the policy of Metrolinx to adhere to the intent of the relevant permit/approval requirements to the greatest extent possible, and to submit applications for review and information.

77 Report to Development Services Committee Item: DS-20-99 Meeting Date: September 14, 2020 Page 14

Metrolinx will continue to communicate and engage with local municipalities, including Oshawa, during the detailed design and construction phases, as follows:

. Metrolinx will consult with, and have regard for, municipal planning policies with regard to specific projects (or components thereof) and will comply with municipal requests when and where reasonable and feasible;

. When developing plans for new or expanded infrastructure, Metrolinx will coordinate with municipal staff to ensure infrastructure is constructed to meet municipal requirements to the greatest extent possible; and,

. When possible, construction will be limited to the time periods allowed by the locally applicable municipal by-laws, taking into account that certain types of construction work can only be completed at night when trains are not in service (i.e., outside of business hours).

Metrolinx has committed to the following actions with respect to consultation with municipalities during the detailed design and construction phases:

. Traffic, parking, transit, cycling and pedestrian management strategies will be included in construction contract documents in coordination with municipalities, as appropriate, to avoid/minimize interference to the greatest extent possible;

. Metrolinx will confirm the locations of any additional required contractor staging/storage areas which may necessitate leasing agreements with private property owners and/or the municipality;

. Metrolinx will engage municipalities during construction planning/scheduling to ensure that any municipal concerns are addressed in the construction plans prior to commencement of construction activities; and,

. Metrolinx will continue to coordinate with municipalities during the detailed design phase on matters related to land use planning and design.

5.3 Project Timelines

Metrolinx’s planned milestone dates for the T.P.A.P. are as follows:

. Impact Assessment Studies – November 2019 to July 2020 . Public Meeting Round 1 – February 2020 [ten (10) in-person meetings were held between February 18, 2020 and February 29, 2020] .

78 Report to Development Services Committee Item: DS-20-99 Meeting Date: September 14, 2020 Page 15

5.4 City Comments on Draft E.P.R. Addendum

Having reviewed the Draft E.P.R. Addendum, staff recommend that the following comments be provided to Metrolinx for its consideration in advance of the E.P.R. Addendum being finalized and the Notice of Commencement being issued:

. The potential impacts to the existing Oshawa GO Station should be clearly identified. In this regard, Metrolinx is requested to confirm whether or not the pedestrian walkway to the west parking lot and the bus loop will be affected during construction, and if so, whether these facilities will be shifted north on a temporary or permanent basis. Likewise, potential effects on the number of parking spaces being provided during construction are requested.

. Metrolinx is requested to confirm whether the existing storm sewer outfall located near the area of the proposed station platform, and the associated storm sewer easement, will be affected. Likewise, confirmation is requested as to whether there will be any potential effects due to construction on the outfall structure or the drainage ditch leading east, including due to overland flow. Staff note that the storm water management infrastructure at the Oshawa GO Station and along the adjacent segment of Thornton Road South are owned by the Region of Durham.

. Metrolinx is requested to give the City the opportunity to provide comments during the detailed design phase for the proposed works, including in relation to the storm water management system and any potential effects.

. Information regarding any potential effects on existing service during construction is requested as soon as possible, in order to inform riders so they may be able to adjust their commuting schedules accordingly.

. Confirmation that the provision of electrification infrastructure will not adversely affect the timing of the planned Bowmanville Rail Service Expansion along the CN/CP line is requested.

. City staff request that a concept plan be provided to demonstrate how the proposed electrification infrastructure in the Draft E.P.R. Addendum would integrate with the existing and proposed tracks and platforms at the Oshawa GO Station required for the Bowmanville Rail Service Expansion.

. Staff will request that one or more of the Public Meeting Round 3 events be held in Oshawa.

Re: Metrolinx OnCorr Program – GO Rail Network Electrification Transit Project Assessment Process – Draft Environmental Project Report Addendum

Metrolinx and Hydro One (as Co-Proponents) are seeking your comments on the attached Draft Environmental Project Report (EPR) Addendum for the GO Rail Network Electrification Project.

Metrolinx, an agency of the Province of Ontario, is expanding its services as part of the GO Expansion Program, which will increase services both in terms of train frequency and availability across its seven rail corridors. The GO Expansion Program is an investment program that will transform GO Rail into a comprehensive regional rapid transit network system that provides the expanded mobility the Greater Toronto and Hamilton Area (GTHA) needs to accommodate growth and maintain a high quality of life and prosperous economy. The long-term goal and vision of the GO Expansion Program is to provide 15-minute, two-way, all-day service. With major investment in GO Rail infrastructure, Metrolinx will be quadrupling GO Rail service and nearly doubling GO Rail ridership. By 2055, annual ridership will exceed 200 million, compared to 105 million without GO Expansion. As part of this program, Metrolinx will be providing 15-minute two-way, electrified service along several rail corridors.

Metrolinx and Hydro One are completing a Transit Project Assessment Process (TPAP) Addendum under Ontario Regulation (O. Reg.) 231/08, Transit Project and Metrolinx Undertakings to assess the effects of changes to the proposed transit project, and to provide mitigation measures.

The Project

On December 11, 2017 the Minister of the Environment and Climate Change (now referred to as Minister of the Environment, Conservation and Parks) issued a Notice to Proceed to Metrolinx and Hydro One for the GO Rail Network Electrification TPAP to convert six GO owned rail corridors from diesel to electric propulsion. Metrolinx subsequently issued a Statement of Completion on December 15, 2017.

As part of the GO Expansion program, Metrolinx has identified various infrastructure requirements to achieve the established service level targets across the network. The GO Rail Network Electrification Project is one component of the broader Metrolinx GO Expansion Program. Specifically, the purpose of this Environmental Project Report (EPR) Addendum is to assess additional electrification infrastructure required for new/upgraded tracks and layover facilities (which are being studied as part of a separate Metrolinx study called “New Track & Facilities TPAP”) proposed across various portions of the GO Rail Network that were not previously examined as part of the 2017 GO Rail Network Electrification Project TPAP.
