Can I travel to Toronto at first, and stay there for a couple of weeks at my sister's house then go to my college in Vancouver? I will have the ticket to Vancouver, and everything prepared. What will be a valid reason to the CBSA officer for me to arrive in Toronto, rather than go to Vancouver? Because staying in Toronto at first will lower my accommodation cost and there will be someone I know in Canada at first. Will it be enough or Do I need to provide more reasons?
