Your country most restrict such as United State but there are have allow to trade trough Binance US, I think if there are not any option for trading trough CEX exchange have been banned for user come from Canada you have one option left with trading on DEX exchange. Its difficult position if exchange get restrict from government but I think you can find any exchange not required for KYC and trade there because can't detected where the user come from.
I used to do trading on bybit and bitmex, but both have banned Canadian user.
Ii don't think both exchange banned the user from Canadian but regarding with your government regulation only not allowed for using both exchange to trade or possibility your government banned with bitcoin as investment assets and for Canadian can trade cryptocurrency in any exchange yet.
