The border between the US and Canada has been closed for non-essential travel since March 21. As of now the border is supposed to be closed through June 21, though it’s now being reported by Reuters that the closure will be extended by an additional month, through July 21.
This would mark the third extension, as we’ve always seen the border closure extended by a month at a time (first through April 21, then through May 21, then through June 21).
This is being done to control the spread of coronavirus. This prevents non-essential travel, but select essential travelers, as well as goods, are still allowed to cross the border.
As mentioned above, there hasn’t been an official update regarding this, though it’s expected that an announcement will be imminent. If you’ve been hoping to cross the border in the coming weeks, that might no longer be possible.
Any travel this summer (especially internationally) really will have to be planned last minute, given how often restrictions are being updated.
