WINNIPEG Canada and the United States have agreed to extend border restrictions for another 30 days, Prime Minister Justin Trudeau said on Saturday. Washington and Ottawa agreed last month to clamp down on nonessential travel while allowing trade to continue across their long shared frontier during the coronavirus outbreak. The restrictions were due to expire next week. Canada’s death toll from COVID19, the respiratory disease associated with the new coronavirus, rose 8% to 1,346 deaths, a government website said. Reported cases climbed 6% to 32,412.
