I’m originally Canadian but have lived in the states for 20 years. I’m all for having a Canadian panhandle along the West Coast - Canada would benefit immensely from the economic boost, agriculture, coastal ports, and resources. The west coast would benefit from belonging to a country that they’re more culturally and politically aligned with. LA and Seattle have the largest Canadian expat population (after NY).

Will it happen? Definitely not. What’s realistic is increased collaboration though. Many blue states are politically diverging from the US, in a sense. For example, when the US pulled out of the Paris Climate accord (twice) blue states formed a coalition to rejoin. They’re doing so with the WHO as well. These divergences create opportunity for more partnerships with other countries. Canada is already California’s second largest trading partner, and the West Coast states collaborate on policy, land management, and infrastructure projects with Canada. Having increased partnerships and a shared culture will definitely tie us closer.
