Because I graduated from the Faculty of Engineering at the University of Waterloo, I got an email about their participation in Go Eng Girl!, a province-wide initiative to show girls in Grades 7 through 10 what engineering is all about. If Waterloo isn't the closest university to you, go ahead and see if something nearer is also participating. I suspect, though, that many of us would like our daughters to take engineering at Waterloo if they're to take it anywhere - the reputation is excellent. (Remain calm if you support another institution; I also have a graduate engineering degree from Toronto and have worked alongside excellent engineers from a variety of universities, so let's not go there. And no, I haven't forgotten the weather in Waterloo.)
