the US/Canada border is not and has never been closed to commerce, only to non-essential travel
I work cargo at an airport: you are correct.
There are essential supplies going both ways. A lot of medicines go both ways and globally.
No country is completely independent no matter what they want to think.
Cargo volume is way up and passenger volume way down. Saw a plane last week that had just been converted from passenger to freight: that tells you where the volumes are.
The pro business lobby in the USA is pushing hard for return to normal, based on their great genius epidemiologist Trump.
If there is a righteous God he would smite everyone in the White House with the virus.
