Canadian Prime Minister Justin Trudeau is invoking emergency powers to weaken the protests by demonstrators who are paralyzing the capital city of Ottawa and blocking border crossings.

The busiest U.S.-Canada border crossing has reopened after protests against COVID-19 restrictions closed it for almost a week, while Canadian officials are holding back from a crackdown on a larger protest in the capital, Ottawa.

Canada’s public safety minister says U.S. officials should stay out of the country’s domestic affairs.
