As you can imagine anything to do with taxes can get complicated quickly. You really need to talk to a tax lawyer, one that you trust (they can overcomplicate issues in about a millisecond). You want to make sure you have your ducks in a row before you (hypothetically) become a nomad so it doesn't come back to bite you later.
OP should definitely visit Canadian tax lawyer first. It's not that simple to become tax non-resident as people usually think.
Yes, the unassailably correct answer to any tax question posed on EliteTrader is 'talk to a professional, dummy'. I'm most certainly not going to take any poster's opinion as gospel. But I've found it's still useful to solicit replies as some may have faced or looked into something similar before and be able to provide some good pointers or links.
What you are writing here is not "standard" for each country. It can be misleading for OP.
