Poor UPS Guy...
I have no complaints with UPS Canada. As long as the stuff is shipped from within Canada.
The issue for us is the nasty brokerage fees. A 50$ part can easily top 100$ after brokerage fees. Once is enough using them for U.S. to Canada shipments.
I now use my friend's storage space in Detroit for U.S. shipments, and go there to bring parts back.
