Ambassador Bridge

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.

A blockade of the bridge between Canada and Detroit by protesters demanding an end to Canada's COVID-19 restrictions forced the shutdown Wednesday of a Ford plant and began to have broader implications for the North American auto industry.

Canadian lawmakers expressed increasing worry Tuesday about the economic effects of disruptive demonstrations after the busiest border crossing between the U.S. and Canada became partially blocked by truckers protesting vaccine mandates and other COVID-19 restrictions.
