The funny thing is that there would be two cities called Vancouver.

But there are two cities called Vancouver. If the British had retained it all there would only be one.

Yes one of them is Vancouver BC other one is Vancouver WA.
But with this new scenario, both cities would have been in the same province.
( If the British had obtained highlighted disputed area as indicated on the map.)

I think if the Oregon Country/Columbia District was given to Canada, we may have needed to fight a war to retain it over the long run. A war that we most certainly would have lost. The USA takes what it wants.

Then our Vancouver would have had a different name, still a similar city, but with much more population to the south. Different political borders would have resulted in a different population distribution, with more to the south still hugging the border. However, our Vancouver would still be a city because of the geography we have here.
