Hi.. My spouse and I are just waiting for our marriage certificate to send out the application to CIC. We decided to apply outland even though I'm currently in Canada on a visitor visa. The question might be silly and kinda ridiculous but we just do not want to make any mistake. We both live in Ontario. I'm a bit confused as to where we should send my application. Should it be to Mississauga?? I just saw that someone from London must send it to Ottawa (very different Brazil#London). I know São Paulo will be taking care of it once it's approved (without any issues hopefully). What are the chances that they will deny my visitor visa extension? Thank you.
