You always hear these sayings and then when you look at acceptance rates in Canadian higher-ed you find that there just aren't that many highly selective schools. Brock isn't an outlier at all; compared to a school like Stanford, for example, literally every Canadian school is wildly more accepting. People just apply to less schools at once (less culture of moving for school) and the schools have far more clear grade requirements --- if you meet them then you have like a 95% chance of getting accepted. There is no insane competitive application process like in the US and no one cares about what school you went to for undergraduate.

It is funny how every school has a saying like that for rivals, though.
