All border-crossing students unlikely to go by all the rules

I don’t agree with Canadian students attending Lake Superior State University being permitted to travel back and forth across the International Bridge on a daily basis during the pandemic.
A couple of weeks ago a man who lives in the United States but works at Algoma Steel won that right in an arbitration ruling.
I didn’t agree with that either.
I couldn’t understand how an arbitration decision could override rules laid down by the Canadian government in closing the border.
