It's a giant undergrad school (36,000 undergrads and barely 6,000 postgrads). There are more undergrads at Waterloo than at MIT, Stanford, CMU, Caltech, Harvard, Princeton and Yale... Combined! and they do coop, meaning their "break" semester alternates from from summer to fall to winter. From what alumni told me, undergrads are incentivized to apply everywhere for internships as part of their courses and especially during the off-cycles (winter) for internships when they are effectively the only ones looking. Coop also means someone who can't convince an employer to pay for them won't graduate, so there's a nice selection bias.
