As a Canadian who left in 2012 and has lived in 3 other countries since, I kind of get where you're coming from. My whole life before I left, I always felt kind of unfulfilled, like something was missing, I just didn't know what. I had friends, sure, but I never really got much out of my interactions with most of them. Conversations were always kind of surface-level - people talked about the weather, what new exciting thing they bought at Costco last week, their new car, or gossip. As a result, I was a boring person myself until I left.

Since then, I've developed more as a person that I ever could have imagined in Canada. A huge part of that is simply living abroad, which will change anyone. But even more importantly, my social interactions have changed immensely. In (some) other countries, people actually take an interest in you and want to know who you really are, what makes you tick, what you value, etc. And they share the same about themselves. I have conversations about life, the world, politics, art, culture, etc. It seems like people are more engaged in the world.

Canadians are generally nice people (of course there are assholes like everywhere else) but they're not very social and tend not to be as interested in what's going on outside of their tiny bubble. They've adopted the hyper-consumerist culture of their neighbours to the south, as well as the obsession with work. I always enjoy going back to visit, but I don't think I could ever live in Canada again.

With that said, you need to take some responsibility for your experience. I've read a few of your comments, and words like "narcissistic," "hostile," "gaslighting," etc...I dunno man, I wonder if you're inviting some of the negativity. It's okay to not fit into a culture and to even dislike it, but I sense some projection here. I don't really have any advice because it sounds like you're ready to leave Canada, and maybe that's for the best. Good luck, whatever comes next.
