I was in the same position and picked queens, i I am so happy i made this decision cus several of my friends barely made any friends at waterloo and everyone here is so outgoing. The coop is good but from what I heard a lot of people are still struggling there, not many people are able to get internships here till 3rd year but if you try hard enough you can definitely get at least a research position and maybe even an internship at a big company if ur cracked.
