For psych, just go to the school closest to you because it's all the same. This is only undergrad. Reputation only matters for grad school. Plus, the prestige between these two schools aren't really an important factor because they're both among the largest schools in Canada in terms of student population and both have acceptance rates above 50%. Toronto is almost identical to Vancouver in the sense that they're both two metropolitan cities, but of course the weather in Central Canada is far worse than west coast Canada. They're both difficult to do well in because you're competing with thousands of other smart people, it won't be a cake walk either way.
