Lots of used Canadian trucks on the local Ford lots

The exchange rate is the main reason that it's hard to find a good older truck up in Canada right now.

On the other hand I've heard you can get a reasonable offer on your older trade-in, and the dealer just ships them to the States.

But watch the warranty. The US dealers don't honor the Canadian warranty and vica-versa. So AFAIK it's really only out-of-warranty trucks that are moving across the border, unless soemthing else is arranged.
