Blatantly funded by the US. Where are all the "foreign interference!!!" Conservatives now? How is this legal??
There's no unilateral separation from Canada without reconciling all of the constitutionality protected indigenous land claims, and they've all indicated they have no interest. Also the Constitution would need to be renegotiated, and this would require all provinces. This will stretch any practical timeline for secession out indefinitely.
The US interests have no bearing on this, unless they plan on invading.
