I am pleased to submit our interim report — Public Transit: Back on Track. In this initial phase, we were mandated to examine the feasibility of the Sheppard Subway extension and more generally, to examine the feasibility of a future integrated transit network utilizing subway [heavy rail] technology wherever possible for Toronto and the Greater Toronto Area [GTA]. While contemporary families are diverse in socio-economic terms, we are all confronted by a common problem — congestion on our roads and the lack of an integrated, fast, reliable and safe transit network. This transit deficit has the most profound impact on our underserved [in some cases, unserved] priority neighbourhoods in which the residents are totally dependent on public transit — “transit-captives” would be a good descriptor! Many reside in social housing without access to an automobile or are members of the cohort known as the “working poor” with limited access to a car. This phenomenon has plagued us, been discussed and examined countless times by countless recognized authorities ad nauseam. The frequently repeated phrase “integrated transit network” is in danger of becoming nothing more than a cliché if substantive and sustained action is not taken soon. The growing transit deficit has, not unexpectedly, evoked anger, frustration and cynicism from residents as to the sincerity of our political leaders. Many could be forgiven for thinking that politicians are really only interested in their near-term electoral prospects and their legacies when they see them grasp at quick fixes which are often second-class rather than first-class plans. Public Transit: Back on Track reflects discussions [both formal and informal] that took place over the last several months with planners, engineers, lawyers, financiers and experienced, open-minded transit operators. The historical development and socio-economic context of subways was also reviewed. The focus was kept on the impact of our transit deficit on contemporary families and employers. In other words, we reviewed past decisions, planning documents, and technical specifications and impact analysis for the Sheppard Subway before arriving at conclusions and recommendations. The health and well-being of the residents of Toronto and the GTA was/is paramount in our consideration of this pressing issue. Toronto Transit: Back on Track — Toronto Transit Infrastructure Limited A Public Transit: Back on Track is focused on the P3 procurement potential of subways and is mindful of municipal structural deficits and fiscal limitations. It calls for a bold transformation of our transit system, how it is governed, managed, funded, and partners with senior levels of government. It embodies a sustainable use of urban space together with innovative subway funding and financing approaches. After the last 9 months of work is tabulated, there is only one inescapable conclusion: The subway option is the most cost-effective and environmentally friendly technology for the Sheppard corridor. It is the only technology that will deliver real and measurable benefits for the residents and commuters of Toronto, and improve regional competitiveness. It is the only technology that will get Torontonians out of their cars and on to public transit. Additionally, securing financing from the private sector is both feasible and desirable for the City. History illustrates inaction has a cost. Delays in construction simply transfer the burden of fixing our transit system onto the next generation; the cost of this burden escalates over time and is significantly greater the more we delay construction than employing innovative revenue and financing tools. Social equity demands we provide the most vulnerable groups within our society and the underserved priority neighbourhoods with the same level of transit as found elsewhere in the City. It requires we provide reliable, convenient and rapid access to our cultural and sporting venues such as the ROM, AGO, Massey Hall, Rogers Centre and the Air Canada Centre. It requires us to search and employ the very best solutions that are on offer. The Sheppard Subway remains an approved transit project for the City of Toronto. It was first included in the Official Plan in 1980, as part of the Major Centres policy. Thirty years of planning studies and detailed technical and functional specifications exist. It’s time to get public transit back on track. Before concluding, I must express my deepest gratitude to Dr. Jo Kennelly who tirelessly went through TTC and Council minutes, examined international best practices, worked with Metrolinx and KPMG to ensure accuracy of data with respect to growth, development and cost calculations and met with countless transit experts and innovators who were eager to offer their expertise and experience to benefit the City the Toronto. The City of Toronto Finance and Planning staff and KPMG consultants must be thanked for working diligently and often overtime to support the development growth and capital financing analysis and options. Metrolinx staff and consultants were also of enormous assistance, as was staff from the federal agency PPP Canada. Two volunteers who care deeply for the city, Doug Turner and Steve Fry, provided many hours of valuable input. A City of Toronto engineer [working on weekends], who also lives in the eastern part of Scarborough, provided a well thought out alternative plan which should be given due consideration in the future. We have delivered on our mandate within the timeframe and limited resources provided. We believe that our Interim Report – Public Transit: Back on Track – provides the sufficient rationale for the City to move forward with the Sheppard Subway extension. We have demonstrated that this can occur quickly and have articulated a clear work plan for action. B Toronto Transit: Back on Track — Toronto Transit Infrastructure Limited Recommendation TTIL is recommending Council: 1) re-confirm completion of the Sheppard subway linking Downsview to Scarborough Centre; 2) commit to a two-phased approach for construction and completion of the Sheppard subway; and 3) approve TTIL proceeding with the second phase of the project, including establishing robust corporate governance and management structure for TTIL, updating design and environmental assessment work and examining in further detail delivery model and procurement options. On behalf of TTIL [Co-chair Councillor Norm Kelly and Director Councillor Doug Ford]. Respectfully, Gordon J.

  • Friend of Ex Toronto Mayor Rob Ford Ill As Trial Sputters
    Friend of ex Toronto mayor Rob Ford ill as trial sputters THE CANADIAN PRESS TORONTO – A hearing into drug charges against a friend of former Toronto mayor Rob Ford began Tuesday with the accused a no show, one count against him withdrawn, and his co-accused making an extraordinary request to be excused from trial. Alexander (Sandro) Lisi, who was also Ford's sometimes driver, was ill and did not appear for what was to be the start of the trial, forcing a premature end to the day's hearing. His lawyer, Domenic Basile, told court Lisi sufers from vertigo and his mother said he had been throwing up. ``It could be a few hours. It could be a few days,'' Basile replied when Ontario court Judge Ramez Khawly asked when Lisi would be well enough to attend. Ultimately, Khawly put the hearing over until Wednesday, warning that if Lisi did not appear, ``all bets are of.'' Lisi, 36, was charged in October 2013 as the ``crack video'' scandal engulfed the notorious former mayor, now a city councillor. The charges against him and co-accused Jamshid Bahrami – both are out on bail – arose as police investigated Ford amid reports of a video that apparently showed him smoking crack cocaine. At the time, Ford called Lisi a ``good guy'' and expressed shock at the charges. In a highly unusual request, Bahrami, a west-end dry cleaner, asked to be excused from the trial. Bahrami, 47, sufers from a chronic, degenerative form of rheumatoid arthritis that leaves him in constant pain, said his lawyer, Jacob Stilman, adding his client's condition would never get any better.

  • The Politicization of the Scarborough Rapid Transit Line in Post-Suburban Toronto
    THE ‘TOONERVILLE TROLLEY’: THE POLITICIZATION OF THE SCARBOROUGH RAPID TRANSIT LINE IN POST-SUBURBAN TORONTO Peter Voltsinis 1 “The world is watching.”1 A spokesperson for the Province of Ontario’s (the Province) Urban Transportation Development Corporation (UTDC) uttered those poignant words on March 21, 1985, one day before the Toronto Transit Commission’s (TTC) inaugural opening of the Scarborough Rapid Transit (SRT) line.2 One day later, Ontario Deputy Premier Robert Welch gave the signal to the TTC dispatchers to send the line’s first trains into the Scarborough Town Centre Station, proclaiming that it was “a great day for Scarborough and a great day for public transit.”3 For him, the SRT was proof that Ontario can challenge the world.4 This research essay outlines the development of the SRT to carve out an accurate place for the infrastructure project in Toronto’s planning history. I focus on the SRT’s development chronology, from the moment of the Spadina Expressway’s cancellation in 1971 to the opening of the line in 1985. Correctly classifying what the SRT represents in Toronto’s planning history requires a clear vision of how the project emerged. To create that image, I first situate my research within Toronto’s dominant historiographical planning narratives. I then synthesize the processes and phenomena, specifically postmodern planning and post-suburbanization, that generated public transit alternatives to expressway development in Toronto in the 1970s. Building on my synthesis, I present how the SRT fits into that context and analyze the changing landscape of Toronto land-use politics in the 1970s and early-1980s.

  • Fare Hike Called 'A Small Band-Aid on a Big Problem' Changes Will Bring in an Extra $50-Million, but Cover Less Than Half an Estimated Shortfall for 2010
    Fare hike called 'a small Band-Aid on a big problem' Changes will bring in an extra $50-million, but cover less than half an estimated shortfall for 2010 ANNA MEHLER PAPERNY TORONTO — From Wednesday's Globe and Mail Published on Wednesday, Nov. 18, 2009 The Toronto Transit Commission passed a slate of fare increases yesterday, while vowing to review a funding model so broken that staff say they may have to impose similar fare hikes for the next several years just to cover operating costs. The new fares, which come into effect Jan. 3, slap an extra 25 cents on the price of a single ride, now $2.75 for cash payment, and raise adult monthly Metropasses from $109 to $121. University and college students got a break, as the rate for monthly passes for seniors and high-school students, which will cost $99 when the changes come into effect, was extended to postsecondary students. The changes will bring in an extra $50-million for the TTC next year, but will cover less than half an estimated $106-million funding shortfall for 2010. The commission still doesn't know where the extra $56- million will come from, as the city struggles with a budget shortfall that could be as much as $500-million. Premier Dalton McGuinty said at a news conference yesterday that the province, which faces a $24.7-billion deficit, won't be bailing out Toronto's transit system. TTC Chairman Adam Giambrone said he's opposed to service cuts, but said they'll be looking for "efficiencies" in operations in an attempt to close the funding gap.

In total there are currently approximately 68 km of subway tracks and 69 stations. Over one million trips are taken daily on the TTC during weekdays. The subway system has been expanded in several stages, from 1954, when the first line (the Yonge Line) was opened, to 2002, when the most recently completed line (the Sheppard Line) was opened. Currently the Toronto-York Spadina Subway Extension is under construction. The subway tunnels have been constructed using a number of different technologies over the years including: open cut excavation, open/closed shield tunneling under ambient air pressure and compressed air, hand mining and earth pressurized tunnel boring machines. The subway tunnels range in design from reinforced concrete box structures to approximately 6 m diameter precast concrete segmental liners or cast iron segmental liners.
