Call ICBC get a 7 day permit. Allows you to drive from A. to B. They will fax it directly to registry or email.
Go to registry in alberta and get a permit 24 hours good enough.
Drive back to BC.
Pay PST on vehicle./ out of province inspection etc
Make sure you have the reggy forms from the owner of the vehicle!!!!! ICBC will NOT take alberta bill of sale form only, they must have previous reggy form.
I have done this 10 times ++++ very easy as long as you have the reggy form from previous owner.
Sometimes you have to take a chance, whether that be on someone, or something!
