美加边境限制又延期到七月21号，虽然没有证据说美国游客把病毒带到加拿大

DETROIT – The United States and Canada have agreed to extend the border closure another 30 days, putting it in place until July 21, according to multiple reports.

Canada Prime Minister Justin Trudeau made the announcement Tuesday during a news conference.

Non-essential travel between the United States and Canada has been banned since March amid the coronavirus pandemic. The border crossing ban began March 21 and was extended another 30 days in April.

The border was set to remain closed to non-essential travel through at least June 21, and now that is extended until July 21. Travel restrictions still do not apply to healthcare workers, trade and people going to and from work.
