Key US-Canada bridge reopens as Ottawa protest persists

The busiest U.S.-Canada border crossing was open Monday after protesters demonstrating against COVID-19 measures blocked it for nearly a week, but a larger protest in the capital, Ottawa, persisted as city residents seethed over authorities' inability to reclaim the streets.

Demonstrations against COVID-19 restrictions and other issues have blocked several crossings along the U.S.-Canada border and hurt the economies of both nations. They also inspired similar convoys in France, New Zealand and the Netherlands. The U.S. Department of Homeland Security warned that truck convoys may be in the works in the United States.

Police in Windsor, Ontario, arrested 25 to 30 protesters and towed several vehicles Sunday near the Ambassador Bridge, which links Windsor, and numerous Canadian automotive plants, with Detroit. The bridge reopened to traffic late Sunday night, a spokeswoman for bridge owner Detroit International Bridge Co. confirmed. Canada Border Services also confirmed that the bridge is open.

After protesters began blocking bridge access Feb. 7, automakers began shutting down or reducing production, at a time when the industry is already struggling with pandemic-induced shortages of computer chips and other supply-chain disruptions. The crossing sees 25% of all trade between the two countries.

"Today, our national economic crisis at the Ambassador Bridge came to an end," said Windsor Mayor Drew Dilkens.

"Border crossings will reopen when it is safe to do so and I defer to police and border agencies to make that determination."
