Here is my opinion:
1. Some MBA programs here in Canada focus more on your academic background, while some others consider your working experience more. For example, I contacted with McGill's appication officer last year and she said their requirement is 85 points on 100 points system. When I asked did that mean if my GPA is lower than that I should not apply. Guess what? She simply replied: YES. ( I did not applied for that program.)
2. You can give UBC a call and ask what's their minimum requirement on GPA and what's the average GPA of the students they accepted. If your GPA is really below their requirement, you can also ask whether anything can be a compensation for that, say a high GMAT score or something.
