Overview
- Federal officials and Alto are developing a proposed 1,000‑kilometre electrified line designed for speeds up to 300 km/h that would cut Toronto–Montreal travel to about three hours.
- The government has committed $5 billion for planning and set a formal decision point in 2029 to approve or stop construction.
- This week Transport Minister Steven MacKinnon signalled a strong preference for a Kingston stop, a change that would push the route farther south and has sharpened opposition in Eastern Ontario from rural residents and environmental groups.
- Alto’s headline estimates show construction costs of roughly $60 billion to $90 billion and long‑range ridership of 24 million annual passengers by 2055, but route details, station sites, service levels and a final budget remain unresolved.
- Mayors are urging near‑term upgrades to existing passenger tracks and stations to improve connections to the proposed line, while researchers warn high‑speed rail megaprojects commonly face large delays and cost overruns.
