high level figures in the EU have repeatedly stated that while they appreciate the gesture, Canada wont ever be a member. So its best to abandon those pipe dreams. When it comes down to the details, the EU is a boys club for Western and Central Europe, they dont even treat their Eastern members as anything more than a buffer zone against the Russians,
the EU isnt flawless either, Russia has infiltrated it with trojan horse governments like the Hungarian Fidesz party and the Slovakian SMER party, who embezzle EU funds and politically roadblock motions with their veto. Canada trying to decouple with the US just to dive into the EU is like running from a burning house into a house with a basement meth lab.
