One more thing that might sway you to SFU: SFU Open Undergraduate Scholarship. After your Entrance Scholarship finishes its disbursements, if you achieve a CGPA of ~3.60, you're automatically eligible for the Open Scholarship which awards ~$110 per unit you take. So (in ENSC) at an average of 17 units per semester, that's roughly $1800 in scholarship funds. That's not an insignificant amount of money, if you're decent at studying.

If you can spin a good essay, you have a good chance... SFU gives 40 Gordon Shrum awards per year, $24,000 each. UBC's is by school nomination--if you can get a nomination from your school, apply for that too!
