As a UW grad, I can tell you that most of the best talent from those universities does not go to RIM, and hasn't for a number of years. Sure they have a few really excellent people, the few who want to sacrifice better opportunities to stay local and don't find Google (who have a Waterloo office) appealing, but the majority of the people in my graduating class who went there aren't engineers I'd want to work with. And very few of the people they hire would make it through the hiring process of top companies like Microsoft, Google, Apple, Facebook, etc.
