since i'm not a canadian, i don't know what exchanges support leveraged trading in canada. but you should be able to use vpn on binance and trade from there, there should be no problem with that. then if you want to withdraw to your wallet, you can do it to an exchange that is supported in canada. tricks like this have been used by many traders who are hampered by regional restrictions, but still want to trade crypto.
It is bad advice to use the Binance exchange for residents of Canada, because this exchange prohibits citizens of this country from trading on the Binance. Using a VPN will not help, since it is mandatory to pass KYC on Binance, which will be impossible for citizens of this country to do.
