Getting into computer science at UBC or SFU is not nearly as competitive as getting into compsci at UW, UOregon, Berkeley, CU-Boulder, UAZ or other Pac-12 schools. It's cheaper for an international student to study at UBC than it is for a U.S. citizen Washington state resident to study at one of the Seattle Community Colleges (Seattle Central, North Seattle, Shoreline, etc.)

Compsci is so competitive at U Dub that even safety majors like HCDE, Informatics. ECE, and even pure science majors (Math, Physics, Statistics) that are at least somewhat related to computing have become extremely difficult to get into; and this is assuming you're a Washington resident and going the smart route via community college. /r/udub has a good post on CSE. GPAs required have hovered around 3.6-4.0 on a 4.0 scale. (based on UW's grading scale, that's 91-100% in the UBC scale, and 4.0-4.33 on the SFU scale.)

Plus, UW is expensive. So are Berkeley and the other California schools. UW is $14k USD ($18,700 CAD) a year just for tuition. For the record, tuition at community college in BC hovers around $3,000 per academic year, and university tuition is $5,000-5,500 per academic year. Berkeley is so expensive that I've heard stories of marriage proposals just to get in-California state tuition. It's crazy.

Getting into compsci at UBC is tricky, they require a B+ which is 76-79% minimum or 3.33/4.33 on the SFU scale. SFU is a bit of a dark horse, a medium sized university without UBC's prestige, so admission into compsci is less competitive. You can either apply into the major directly with a 2.80/4.33 (a low B, 70%ish at UBC?) or apply for an easy major like Geography and do an internal transfer into compsci as long as the three highest math/computing course grades equate to a 2.67/4.33 GPA. They only count first attempts, though.

So, the TL;DR is, university in BC is cheaper than in Ontario and the US, and less competitive. Quebec is cheaper, but fuck Quebec.
