Quick Fact
It's about 127 miles (204 kilometers) as the crow flies. But if you're driving, you're looking at roughly 145 miles (233 kilometers) on the road. Honestly, you can make the trip in around 2 hours and 15 minutes with normal traffic, including the border stop.
Geographic Context
Sitting almost directly east of Detroit, London, Ontario is a key Canadian city in the southwest. That puts it right in the thick of the Great Lakes region's economic and cultural scene—part of what some call the "Detroit-Toronto corridor." To get there, you cross the Detroit River (using either the Ambassador Bridge or the Detroit-Windsor Tunnel) into Windsor. From there, it's a straight shot northeast on Ontario's Highway 401, which is famously busy. All that makes London the first major Canadian city you'll hit coming from Michigan.

Interesting Background
Now, this easy drive is a pretty modern thing. The cities were always close, but good roads needed the Ambassador Bridge (finished in 1929) and the Detroit-Windsor Tunnel (opened in 1930). Here's another quirky fact: Canada didn't always drive on the right. The whole country finally switched over when Newfoundland joined in 1949, which matched U.S. rules. That got rid of a huge headache for cross-border trips and basically locked in the Detroit-London route as a major link between the two countries.
Practical Information
If you're planning a trip, remember you'll need a valid passport or another approved travel document for the border. You should expect some wait at Customs, too. Once you're in Canada, speeds on Highway 401 are in kilometers per hour (it's usually 100 km/h, or about 62 mph). Generally, you can turn right on a red light in Ontario after a full stop, unless a sign says you can't. Your U.S. driver's license is just fine for visiting. For the latest on border waits and entry rules, your best bet is to check the Canada Border Services Agency site before you go.
