It's not worth stressing over. If not Canada then you can pick from lots of other places. You have almost all of Europe to choose from - and this is without needing to jump through hoops and circles just to be allowed in.

Relax and stop treating this like a momentous decision that will either make your life or break it, because it won't. You are still young with plenty of opportunities that abound. Stop focusing on just one option and pretending that nothing else will work. Be flexible and keep an eye on Europe in case Canada isn't keen on letting you in just yet.
