The Ontario Line project is Toronto’s largest and most complex transportation project to date. The project sees a 15.6 km rapid transit line connecting Exhibition Place to Eglinton Crosstown LRT at Don Mills Road, adding 15 new stations to the city. The transit system will feature a combination of tunnelled and elevated sections, along with maintenance and storage facilities for subway vehicles, as well as transit connections to existing GO train services, subways, buses, and streetcar routes.
