Doesn't Quebec export electricity to the eastern US States? In addition to being among  USA's top largest trading partners. 

Certain brands of motor vehicles we see here at retail assembled there, names like GM. Also there's that NAFTA & other deals going on. They do a great export of resources in addition to manufactured goods; plus trade with many former British Empire nations.

The few times I've gone through Canada over the past 50+ years, most have been fairly good trips; and generally most people are cordial, polite, genuine. A few in small border
towns above Montana were about like the cowboy towns south of those crossings; in the early 1970s there were a few bad characters along the roads leading to Alaska Hwy.

We were given incorrect change, enough to rent a motel room and get a meal, when one of the fuel station attendants was so intent on putting the screws on us, they did not
notice after being rude & treating us poorly. 

So we didn't say a thing. Exchange rate error? :)
