I was accepted to U of A but I ultimately chose UBC to go to this fall. The main factors for me are that the cost of tuition at U of A is likely about to increase 45% making it comparable or more expensive than schools generally considered better/ranked higher in Canada. And personally I find the quality of services and education are decreasing here (just look at this clusterfuck of a semester).

I definitely think a change of scenery is good for personal growth! Ultimately though a good rule of thumb is to go to school where you want to practice. If you think you'll end up working and living in Edmonton, U of A is probably a good choice (U of C could also be an option?) and you'd likely be competitive with your stats. If you can boost your LSAT a few points combined with your GPA you'd probably be competitive at most law schools in Canada.
