Thank you for reaching out. Our plan is to maintain streetcar service during construction, and we are working closely with the City and TTC to keep Toronto moving. This is a work in progress, and we will share more on these plans once they are finalized.
Please know that any temporary or planned disruptions to existing transit service will be communicated as early as possible using a number of communications channels to ensure everyone gets the information they need to keep moving.
Regarding excavation, our priority is to keep our construction footprints slim, property impacts to a minimum, and construction sites safe. We are exploring a number of techniques to construct the Ontario Line, including tunnel boring, sequential excavation or mining, and cut and cover methods. Current plans in this area envision using the sequential excavation method (SEM) to tunnel through this area.
Techniques will vary based on the safest, most effective approach for the type of ground we’re working in and how much space is available to carry out the work. In this area of the city, we plan to tunnel through deep, sturdy layers of shale, which will help significantly reduce noise and vibration during construction and operations and allow us to use the SEM/mining construction technique. Any approach we take will be respectful of surrounding community spaces.
Our project teams addressed questions about construction methods in this area during our virtual open house last night, which you can watch
here.
