False. There are many women in Waterloo, of which I am one. My chemical engineering class was about 32% female, but many of the programs at Waterloo have more women than male in them.
While Waterloo often does seem to be about 178.72% male, parts of engineering are at parity (chem eng was 50/50 a few years back) and there are entire other faculties with lots of lovely people for you to make friends with.
