No one knows what sort of documentation will be required to cross the border so I will be content to wait and see. I'm located less than 3 hrs from Fort Francis so it is an easy trip for me and I usually cross in the middle of the week.
I recently took a trip to Hawaii and was required to have a negative 3 day test to avoid a quarantine. Hawaii had a website registration that I had to post my test info to and I received an email copy of the test results.
The test process was easy. I stopped by the local Covid testing center and only had to wait for about 5 mins. They preformed the test and I got my results the next afternoon about 36 hours later via email. When we arrived in Kona we exited the plane I showed them the test confirmation on my phone, they took my temp and I was on my way.
One of the guys who regularly goes on our several annual trips says he will never take a test or get vaxed so I guess he's out till the border crossing has no Covid protocols.
