It's crazy. Why would Canada care if you quarantine for all the time you are there, but leave before 15 days? My parents have been locked up for 3 months already and I (had the virus long ago) want to visit.
Because you can infect people in Canada on the way out?
I am inquiring about an American going into Canada.
They can't
Totalitarian Trudeau
Him and the governments of Australia, NZ, HK, Taiwan, Vietnam, Thailand, Singapore, China, Japan, SK, Kuwait, UAE, and many more
I had heard it was different going Canda to US because (at least in YYZ) you pre clear US customs on Canadian soil, which somehow allows you to enter the US without an essential reason.
US has no restrictions on Canadians entering the US, or people entering the US from Canada. PreClearance makes no difference.
