It would be completely unconstitutional for BC to stop Alberta from using the ports, obviously. Despite the fact that this hasn’t gone through the courts, even our resident pretend internet lawyer would say so.
But BC will simply take Alberta to court, win, and get reparations. Can’t let bullies get their way.
I am looking forward to less Alberta tourists with their slow RVs clogging up my roads... threats of a BC boycott, blah, blah... but there will be just as many Albertans vacationing in BC as ever... they either vacation here, or move here. Most of Kim City is populated by Albertans these days.
