Well I'm from Canada and moved to England. It's okay here, could be better though (example English food isn't great imo, maybe besides the occasional fish & chips).
I'd say Japan would be on top of my list, I love pretty much everything about it. Japanese food = looooove!
For other countries I like, I would rather just visit them.
Maybe return to Canada would be another choice. I never fully realised how nice my country is until I left it. Ironic. Maybe some other province though, just for a change. I've never been to British Columbia, and from what I hear it's nice there (good climate as well). Or maybe Ontario, since it's right beside Quebec.
