Detroit to Toronto by road
The fastest driving route is 231 miles (371 km) long and takes about 4 hr 30 min without stops or traffic. Almost all of it is on Highway 401: 218 mi of 231 mi.
Almost the whole route stays in Canada. The stretch in the United States, leaving Detroit, is under 500 m (a third of a mile). That’s an average of 52 mph (83 km/h). AAA recommends a break every two hours or 100 miles: with 2 stops of 20 minutes, the trip takes about 5 hr 10 min. The time is OSRM’s estimate with OpenStreetMap data: no traffic and speeds somewhat below the limits, so real trips can differ.
Straight-line distance and bearing
In a straight line, the shortest distance over the Earth’s surface, Detroit and Toronto are 208 miles (334 km) apart. That’s the geodesic on the WGS84 ellipsoid, the distance “as the crow flies”.
The road is 11% longer: for every 100 miles in a straight line you drive 111. The route runs almost straight. Of the 16 US–Canada and US–Mexico driving pairs in this series, it ranks 14th for detour (the average is 22%).
From Detroit, Toronto lies to the northeast (bearing 62°), and from Toronto, Detroit lies to the southwest. The straight line reaches Toronto on a bearing of 64°: on a sphere the bearing keeps changing along the way, which is why the shortest route looks slightly curved on a flat map.
Halfway between Detroit and Toronto
Halfway along the straight line, 104 miles (167 km) from each city, is the point 43.0335° N, 81.2425° W. It falls near London (Ontario, Canada, pop. 422,324), 3.5 mi away.
By road, the halfway point is 115 miles (186 km) from each city, near London (Ontario, Canada, pop. 422,324), 4.5 mi away. The two midpoints are 8.0 mi apart: if you want to meet halfway, the one on the road is the useful one.
