Windsor – Detroit (Ambassador Bridge)

The Ambassador Bridge between Windsor, Ontario and Detroit, Michigan has historically carried roughly a quarter of all merchandise trade between the U.S. and Canada by value, according to the Federal Highway Administration. The newly built Gordie Howe International Bridge stands ready to add a second span with direct freeway connections once it opens to traffic. U.S.-Canada coverage on Cargado is emerging, with growing marketplace activity on this corridor.

What moves through this crossing

Automotive freight defines the corridor, with just-in-time parts and finished-goods moves between Ontario and Michigan plants, alongside broad dry van manufacturing and consumer volume.

Windsor-Detroit is the center of gravity of U.S.-Canada trade. The Ambassador Bridge, a privately owned four-lane span opened in 1929, has historically carried roughly a quarter of all merchandise trade between the two countries by value, according to the Federal Highway Administration, most of it tied to the integrated automotive supply chains of Ontario and Michigan. A second crossing, the Gordie Howe International Bridge, finished construction in 2026 with direct connections between Highway 401 and Interstate 75, though its opening to traffic has been repeatedly delayed, so check the bridge authority for current status before building routings around it.

What brokers should know

  • Automotive rhythm. Just-in-time parts flows set the corridor's tempo, and carriers here are accustomed to tight windows and drop-trailer programs.
  • No transfer-driver system. Unlike the Mexican border, U.S.-Canada loads run direct: one driver, one tractor, one trailer, cleared electronically and driven through. See border transfer for the contrast with Mexico crossings.
  • Paperwork is electronic. Carriers file e-manifests ahead of arrival with CBP northbound-to-south and CBSA southbound-to-north, and customs brokers arrange clearance before the truck reaches the booth.

Tolls and congestion also shape routing decisions on this corridor, and recent reporting shows meaningful truck traffic shifting north to the Blue Water Bridge at Sarnia-Port Huron, which is worth weighing when transit reliability matters more than distance.

Cargado's roots are on the U.S.-Mexico border, and U.S.-Canada coverage is emerging rather than deep. Marketplace activity on the Windsor-Detroit corridor is growing, and Mexico-Canada freight moving in-bond through the U.S. is live on the network today. Brokers with recurring Ontario-Michigan freight can post it and help seed the lane as the Canadian carrier base builds.

Common questions

Is Cargado live for Windsor-Detroit freight?

U.S.-Canada coverage on Cargado is emerging, and activity on the Windsor-Detroit corridor is growing rather than deep. What is fully live today is Mexico-Canada freight moving in-bond through the U.S., a corridor where brokers consistently struggle to find capacity elsewhere. If you run recurring Ontario-Michigan lanes, posting them helps build carrier density where you need it.

Do U.S.-Canada loads transload at the border like Mexico freight?

No. The transfer-driver and transload patterns of the Mexican border do not exist on the northern border, because the same driver and tractor can legally run both countries. Loads clear electronically through pre-filed manifests and drive straight through, which is why door-to-door transit between Ontario and U.S. points is usually just linehaul time plus the queue at the bridge.
