Traffic has ground to a halt at the busiest border crossing in North America, as Canadian truckers and others angry with vaccine mandates spread their protest beyond Ottawa.
Trucks started blocking the Ambassador Bridge linking the cities of Detroit and Windsor late on Monday, closing down traffic in both directions. On Tuesday, entry to Canada remained blocked while US-bound traffic slowed to a crawl. Each day, 8,000 trucks normally cross the bridge, which handles about 27% of trade between Canada and the US. Protesters also targeted another major border crossing in Coutts, Alberta.
