About The Project
With dedicated passenger tracks and peak speeds of up to 300km/h, Alto will significantly reduce travel times-even halve it in some cases-between major cities in the Toronto-Québec City corridor. Through nearly 1,000 kilometres of electrified tracks, the network will help reduce intercity transportation’s carbon footprint while transforming the user experience. As Canada’s largest public infrastructure project, once completed, this initiative will drive the economy and provide an efficient, economic and environmentally friendly transport alternative to air and car travel.
