Canadians care very much about STEM fields.  One problem is not enough women do and it isn't one of discrimination, glass ceilings or anything else other than desire.
Women do dominate science field, however - being veterinarians, and I don't mean looking after gerbils and cutesy doggies, I mean large animal practices looking after horses, cattle, sheep etc.  Clearly women's abilities can't be questioned.
Of course, is not say that there aren't very successful women in all types of STEM fields, just that a lot don't care for it.
