OTTAWA (Reuters) - Canada closed its borders to all foreign nationals, except U.S. citizens, on Monday, and Prime Minister Justin Trudeau urged people to stay at home to help stem the spread of the new coronavirus.

“We will be denying entry into Canada to people who are not Canadian citizens or permanent residents,” Trudeau told reporters at a news conference outside his home, where he is under quarantine.
