Can I spend one night in Vancouver and then take a flight to my college in Toronto as an international student?

I am a Bangladeshi and I will go to university in Toronto. A few of my friends live in Vancouver and I was wondering if I would be allowed to spend a day with them before taking another flight to Toronto. My study permit has been approved by email today but, as far as I know, a visa officer at the airport will give me a study permit (official?) After checking my documents. So I was wondering if the Vancouver airport would allow me to stay a day and catch up with friends, even though my study permit was for a college in Toronto. I will of course have pre-booked tickets for the various flights I intend to take, from Bangladesh to Vancouver, then from Vancouver to Toronto the next day.

Thank you for your time.
