After investigation and July 21 May 11, 2020 May and June 2020 July 2020 enquiry: closure of the mobilization of start of unexpected Mont-Royal teams and excavation detonation while Most likely root cause: Tunnel preparatory work work drilling in a intersected an old bore work face hole containing – No workers explosive residue dating were injured back to tunnel in this event construction in 1912. Unplanned detonation of a century-old explosive charge 32 Cause analysis according to exports
Construction techniques
- Horizontal drill bar with one (1) or four (4) drills mounted to it
- Major limitations of drilling equipment in the era:
Limited ability to position accurately and align the hole Unplanned detonation of a century-old explosive charge 33 Key conclusions from the investigation
The detonation occurred Three primary risks More than one hundred following direct thermal associated with simulations to model the contact with nitroglycerin detonation of an explosive extreme conditions of a residue, not from vibration. charge: detonation. 1. Rock projections Tests established from various 2. Air overpressure analyses based on the minimum standards to be met, in terms of 3. Fumes projections, noise and air quality. Unplanned detonation of a century-old explosive charge 34 Measures implemented to resume modernization work
More than 1 km of 30,000 boreholes clearance required, making required within the context of it impossible for other work modernizing the tunnel to take place concurrently in this zone

Borehole Mont-Royal Tunnel Requirement to be inside a converted container No activity permitted in this area (within 50 metres) Unplanned detonation of a century-old explosive charge 35 Measures implemented to resume modernization work
Strict measures established and approved by the CNESST to resume work, including required employee training Principles to follow during excavation: (or wherever there is a risk of detonating a potential charge)

General tunnel condition 36 beneath McGill College Avenue Status of the situation
2020-05-11 May and June 2020 August 2020 Series of tests conducted during the summer to validate the quality of the Mount Royal Tunnel structure opening of the located between Central Station and Maisonneuve Street closure of the mobilization of Mont-Royal Mont-Royal teams and Tunnel vault Tunnel preparatory work beneath McGill College Avenue Very significant deterioration of this southern section of the tunnel, potentially compromising the structural integrity of McGill College Avenue, due to the permeation of water mixed with de-icing salt for more than 60 years. General tunnel condition beneath McGill Avenue 37 Mont-Royal Tunnel construction
Double vault built beneath existing McGill College Avenue
No waterproofing membrane installed De-icing salt used on the surface General tunnel condition beneath McGill Avenue 38 Structural deficiencies in the southern section
Three sections of the Mont-Royal Tunnel
North section
Central section

Significant reinforcing measures required to ensure long-term Ground integrity of the tunnel
Four scenarios analyzed: Option with the least impact on traffic and the City of Montréal recommended to perform work from the inside.

Exceptional events identified: Reinforcement required and adjustment of work methods to modernize the Mont-Royal Tunnel: COVID-19 impact – Commissioning of the segment from Unplanned detonation of Du Ruisseau to Central Station: fall of a century-old explosive 2023, i.e. an additional 18 months of charge work
General tunnel condition – Close collaboration with the beneath McGill Avenue ARTM and Mobilité Montréal to extend all measures implemented for Deux-Montagnes and Mascouche line users during this period. Updated schedule Effect of the new scope for modernizing the tunnel 42 Testing period on the Deux-Montagnes, Anse-à-l’Orme and Airport branches
Once tunnel modernization is complete: required testing period lasting about six months to Connection of control conduct tests prior to opening the Deux- systems Montagnes, Anse-à-l’Orme and Airport branches. Command Centre in Brossard Cumulative effect on the Airport Branch
- COVID-19 impact of 3 to 6 months, affecting particularly the following elements: - Mobility of specialized labourers - Supply chain - Period of about 6 months required for testing - Delay in launching the tunnel boring machine Schedule when project was launched in 2018 44
