Currently, there is no true "high-speed" train (defined as 250+ km/h) operating between Montreal and Toronto; the journey is primarily served by VIA Rail’s Corridor service, which takes between 4 hours and 45 minutes to 5 hours and 30 minutes. However, there is significant movement on this front. As of 2026, the Canadian government and the private developer "Alto" are in the active planning and consultation phases for a dedicated High-Frequency Rail (HFR) and High-Speed Rail (HSR) network. This "Alto" project aims to introduce trains capable of reaching speeds up to 200–300 km/h, which would eventually reduce the travel time between Montreal and Toronto to approximately 3 hours. While the first segments (specifically Ottawa to Montreal) are expected to break ground soon, the full high-speed connection to Toronto is still several years away from completion. For now, travelers looking for speed typically choose the "Express" VIA Rail trains, which offer a comfortable city-center-to-city-center experience with Wi-Fi and meal service, often beating the total travel time of flying when you factor in airport security and commutes.
