You can drive south from Detroit into Canada!

Almost all of Canada is located north of the United States, except Alaska. In the Lower 48, however, you can get to Ontario by driving due south from Motor City. The Ambassador Bridge joins the largest city in Michigan with its Canadian neighbor, Windsor in Ontario.

What’s more, this is the busiest crossing point between the U.S. and Canada. As a matter of fact, the four-lane bridge carries more than 10,000 commercial vehicles on a typical weekday.

Buffalo, New York

Canada and the United States share a border at the beautiful Niagara Falls in Buffalo, New York and the city of Niagara Falls, Ontario. Canadians and Americans can cross the Niagara Falls International Rainbow Bridge by foot, bicycle, or car 24 hours per day, 365 days per year (unless there is a border crossing restriction).

Houlton, Maine

The small town of Houlton is probably best known for being located at the northern terminus of Interstate 95. This 303-mile-long highway runs from the New Hampshire state line through Maine and then reaches the Canadian border.

Drivers can cross into Woodstock, New Brunswick, from the border. This crossing point is aptly named the Houlton–Woodstock Border Crossing.

International Falls, Minnesota

International Falls is famous for being the coldest city in the contiguous United States. The city’s Ice Box Days festival in January celebrates this chilly fact.

Cross from International Falls into its sister city, Fort Frances, Ontario, via the International Bridge.

Blaine, Washington

The Peace Arch Border Crossing connects Blaine with Surrey, British Columbia. A unique feature of this border area is the binational Peace Arch State Park, where Canadians and Americans can commingle without needing to go through Immigration. The park includes flowers, fountains, and ponds. It is often the site of weddings.

United States-Canadian Border

The U.S.-Canada border is the longest international border shared by two countries. In fact, the border is more than 5,500 miles long. The U.S. and Canada also share one of the most stable and mutually beneficial multinational relationships in the world.

  1. Wow, I had no idea there was only one city in the United States from which you can drive directly south into Canada. It’s amazing how borders and geography can create such unique geographical oddities. I’m always fascinated by trivia like this, and it’s great to see that there are still so many hidden gems and little-known facts waiting to be discovered. Thank you for sharing this interesting titbit of information with us.

  2. Hi! I am trying to do a roadtrip from Maine, USA into Quebec. Does anyone know of a car rental agency that would allow us to rent a car in Maine and drop off in Montreal? I have called a ton of places and simply they either do not know or just do not allow it. Thanks!

    1. Hi Laura – I’ll check with my fellow family travel bloggers and see if anyone has a solution for you!

    2. Hi Laura – I’ve got a friend who has done a similar trip. His parents are scheduled to do the same this summer and booked their car through Alamo. They will be picking up in Quebec and dropping off in Boston. Enjoy your trip!

  3. Having lived in the Detroit area for eleven years this was something I was aware of, but it was not a well-known fact by even those who lived in the area. That’s because the entry to Canada was at the end of the Ambassador Bridge which crossed the Detroit River. We didn’t need passports, just our drivers license.
