I've done this about 3 times now and it isn't as daunting as many people make it seem.
If you have to look for accommodation it isn't necessary to have a place before you go. just stay in a hostel for a week and look around. I don't know if they have it in BC but a share house is the cheapest rent option. Since you're going to be in the same country moving shouldn't be too difficult.
remember that things start to look a lot more expensive when you spend your own money rather than your parents
