How Long Is the Drive From Toronto to Montreal?

If you’re wondering how long is the drive from Toronto to Montreal, the short answer is about 5 to 6 hours of driving time, depending on traffic, weather, and how many stops you make along the way. The distance between the two cities is roughly 540 to 560 kilometers (about 335 to 350 miles), almost all of it on major highways. It’s one of the most-driven corridors in Canada, connecting the country’s two biggest cities, and it’s a very doable day trip or the first leg of a longer road trip through Ontario and Quebec.

The standard route from Toronto to Montreal follows Highway 401 east out of the Greater Toronto Area, through Kingston, and across the Ontario-Quebec border, where it becomes Autoroute 20 into Montreal. This is the fastest and most direct path, and it’s what most GPS apps will suggest by default.

Highway 401 is a busy, multi-lane freeway for most of its length, and traffic can be heavy near Toronto, Kingston, and the approach into Montreal, especially during weekday rush hours. Outside those windows, it’s a relatively smooth, straightforward drive on well-maintained roads.

A handful of things can stretch that 5-to-6-hour estimate:

• Time of day: Leaving Toronto during morning or evening rush hour can add significant time just getting out of the city.
• Season: Winter driving in Ontario and Quebec can mean snow, ice, and reduced visibility, which slows everyone down. Summer weekends, especially long weekends, bring heavier traffic in both directions.
• Border-area traffic near Ottawa: While the direct route doesn’t pass through Ottawa, many travelers choose an alternate route via Highway 417 that does, which adds some distance but lets you see the capital.
• Construction: Highway 401 sees regular maintenance projects, particularly in summer, which can cause slowdowns.
• Stops: Every gas break, meal, or detour adds to your total travel time, even if the driving itself stays the same.

While Highway 401/Autoroute 20 is the fastest way to go, it’s not the only way. Some travelers prefer routes that follow the St. Lawrence River more closely, passing through smaller towns like Cornwall or Morrisburg. These routes can add 30 minutes to an hour but offer a slower pace and more scenery.

Another option is routing through Ottawa via Highway 417, which turns a straight shot into a small detour but adds Canada’s capital to your trip. This works well if you have an extra day and want to break up the drive with a stop in a city rather than a small town.

Kingston sits almost exactly at the midpoint of the drive and makes a natural break, with a walkable downtown, waterfront views of Lake Ontario, and historic sites like Fort Henry. Further east, towns like Gananoque (near the Thousand Islands) and Cornwall offer smaller-scale stops if you want to stretch your legs without a major detour.

If you’re not in a rush, the drive itself can become part of the trip rather than just a way to get from point A to point B.

Knowing how long is the drive from Toronto to Montreal is useful for a single day trip, but the real planning challenge starts when you want to add stops, spread the drive across more than one day, or connect it to a longer loop through eastern Canada. That’s where a tool like Journey Builder fits in.

Journey Builder takes a road-trip idea and turns it into a day-by-day itinerary with real routes, distances, and drive times for every leg, including alternative routes if you want to compare the highway option against a slower, scenic one. It ranks towns along your route and suggests stops, showing whether each is right on your way or how much of a detour it adds, so if you’re weighing Kingston against a run through Ottawa, you can see the actual extra distance and time before you decide. It also suggests how many nights to spend at each stop and builds the rest of the day’s plan around your wake-up time, bedtime, meals, and drive times, so a Toronto-to-Montreal trip with two or three stops actually holds together on the road.

The drive from Toronto to Montreal takes about 5 to 6 hours under normal conditions, covering roughly 540 to 560 kilometers on Highway 401 and Autoroute 20. Traffic, weather, and the route you choose can shift that number in either direction, and a handful of good stops along the way, like Kingston or a detour through Ottawa, can turn a simple drive into a fuller trip.
