Yeah, it’s probably more expensive to design a system that covers Seattle but doesn’t cover Vancouver just because they’re so close. Same thing for Toronto and Montreal. And in there you already have more than a third of the Canadian population.
Plus, the US would massively benefit from having tracking stations outside of their own borders to see much further away. The most direct path from anywhere in Russia or China to the US mainland (sorry Alaska and Hawaii) always passes over Canada with the one exception being from Southern China to Oregon and California, and that route passes over Alaska.

Edmonton is out of the playground, though.
