OTTAWA, Canada — Prime Minister Justin Trudeau says he has invoked emergency powers to try to quell the protests by truck drivers and others who have paralyzed Ottawa and blocked border crossings in anger over the country’s COVID-19 restrictions.

       Trudeau ruled out using the military and said Monday that the emergency measures “will be time-limited, geographically targeted, as well as reasonable and proportionate to the threats they are meant to address.”

       For the last two weeks, hundreds and sometimes thousands of protesters in trucks and other vehicles have clogged the streets of Ottawa, the capital, railing against vaccine mandates and other virus precautions and condemning Trudeau’s Liberal government.
