Two subject that most kids find interesting at some point are dinosaurs and astronomy. For many the interest in astronomy remains even as they move into other careers. If I want to have quiet time on a plane I know that I can't tell the person sitting next to me that I'm an astronomer.
Astronomy is part of the curriculum in all provinces. The Canadian Astronomical Society has established a very nice web site for Canadian Astronomy Education that provides resources for students, teachers, youth groups and others. The site contains information from the history of Canadian astronomy to Canadian contributions to a guide to careers in astronomy. For teachers there are lessons plans and project ideas. For students there are links for learning more about astronomy, ideas for science fair projects and the Canadian Junior Astronomer Program
