The irony is that in 2028, a state with the same population as Canada might hold a referendum about leaving America. This trade dispute just might push California over the edge, and I am not talking about earthquakes.

If America is so out of control and beyond the reach of the Rule of Law and the Constitution that it can elect Trump (recall that he is considered to be potentially a traitor to the Constitution by the Supreme Court), then it is definitely within the realm of possibility that California could separate.
There’s already an agreement with Canada about the Columbia River, that Trump just barely avoided totally messing up.
The problem is, the Columbia, despite the Arrow Lakes reservoirs, will eventually go the same way as the Colorado. For coastal states and provinces, viable desalination is very much the future, as is improved moisture capture for when global warming hits the point where water is dumped at volume where it precipitates at all.
And despite Alberta, Cascadia isn’t really an advantage for BC; Canada’s strength is in its diversity. And Canada’s entire population is about the same as California’s, so any democratic nation made out of California and other states and provinces… would leave everyone but California at a disadvantage.
