I’m from Canada with leftover crypto from way back…am I cooked?

My ex was big into crypto and used Binance back then when it was nonetheless a platform valid in Canada. He helped me purchased all my crypto but never advised me how one can sell. Now I raked up fairly a bit compared to the little quantity I put at first, but since hes my ex there aint no solution to contact him to figure out find out how to get my cash out of this platform.

I heard it’s not legitimate in Canada anymore. FTR, I stay in Canada however my passport is Viet (which is what I used to create my account). Now I can’t even confirm myself to do anything. Can anybody assist?
