This “at the stroke of the pen” idea is fantastical. Actual Canadians would have next to no interest in this. Whole provinces of Canada don’t even want to be part of Canada so their appetite for having the EU parliament and Commission anywhere near them would be slim to none. Having 250million Europeans eligible to migrate to Canada would similarly be dead in the water even if a few people in Toronto and Quebec might warm to the idea of going the other way.

This is not really true. It's an extreme fringe minority in Canada that is massively misrepresented in US media, and largely propagated by AI bots.

The context in the podcast was that EU was too picky in their reform criteria for inclusion for current candidates on the European continent, but that Canada as a modern country would sail past and pass the exam. The ease with which these experts concluded it would make sense for Canada to join struck me, because impact on geopolitical relationship with US was imho too easily overlooked. It is a sentiment I hear more often now, in the news.
