( AP) Canadian  Prime Minister Justin Trudeau is extending travel restrictions that make it mandatory for air travelers to quarantine in a hotel at their own expense when they arrive in Canada. He’s also thanking the country’s two major airlines for extending a voluntary suspension of flights to Mexico and all Caribbean destinations until May 21. The measures were first announced in January. Trudeau is reiterating that now is not the time to travel. He says Canada’s strict travel, testing, and quarantine measures are extremely important. He notes international travel directly accounts for a small amount of cases in Canada and the restrictions are one tool to fight the pandemic. Canada is experiencing more infections, particularly in Ontario, which was slow in re-imposing lockdown restrictions.
