Best Route from Toronto to Montreal: Highways, Stops, and Timing

The Direct Route: Highway 401 and Highway 20

For most drivers, this trip means leaving Toronto on Highway 401 eastbound and staying on it almost the entire way, with a short transition onto Highway 20 near the Ontario-Quebec border before arriving in Montreal. It’s a well-maintained, high-speed route that passes through or near several mid-sized cities, so services, gas stations, and rest areas are never far away.

Driving Time and Distance

The drive covers roughly 540 km (335 miles) one way. Under normal conditions, that’s about 5.5 to 6 hours of driving time, though traffic around Toronto and Montreal’s metro areas can add 30 minutes or more during rush hour. If you want a fuller breakdown of timing by segment, including how weather and season affect the drive, see our guide on how long the drive from Toronto to Montreal actually takes.

Where to Stop Along the Way

Kingston sits almost exactly at the midpoint and makes a logical rest stop, with a walkable downtown and waterfront views of Lake Ontario. Further east, Cornwall is another reasonable break before the final stretch into Quebec. Smaller towns like Gananoque, near the Thousand Islands, are worth a short detour if you have an extra hour to spare and want a scenic pause rather than just a gas-and-go stop.

When a Different Route Makes Sense

The 401/20 combination is fastest, but it’s not the only way to connect these two cities, and for some travelers it isn’t the most interesting one.

The Scenic Alternative via Highway 7

Highway 7 runs further north and passes through smaller towns and more rural scenery, including stretches near Ottawa if you want to combine both cities into one trip. It takes longer — often an extra hour or more — but it’s a reasonable trade if the drive itself is part of the vacation rather than just a means of getting there. Drivers with flexible schedules sometimes split the difference: take the 401 one way and the scenic route back.

Planning Your Stops and Timing

Picking a road is the easy part. Working out how long to spend in Kingston, whether to grab lunch in Cornwall or push through to Montreal, and what time you’ll actually roll into the city is where most of the real planning happens. A full itinerary with suggested stops, timing, and route alternatives is laid out in our Toronto to Montreal road trip guide, which walks through the drive leg by leg.

Other Road Trips to Plan While You’re At It

If Toronto to Montreal is just one leg of a bigger journey, it’s worth checking routes on either side. Drivers coming from the south might start with the drive from Chicago to Toronto, while those used to planning Northeast corridor trips may find useful parallels in the drive from Philly to Boston, another route where the fast highway isn’t always the only good option.
