UBC and UBCo are completely different
UBCo may be cheaper but the student life is going to be so much different
As others have said Transferring in to UBC is very easy, just make sure your transcripts get sent and if you are applying for next September you should have an answer by April/May
You might want to get in touch with the UBC counselors if you don't want to go through the Calgary ones, they will help you in anything you need and when I have talked to them they were always very friendly and helpful

I have a few friends who went to UofC because they wanted to branch out and get away from home but half of them transferred to UBC after a year and haven't regretted it, its a great school
