Canadian and World Studies

The Canadian and World Studies Department is proud to offer a variety of courses dealing with everything from our compulsory courses (Geography, History and Civics) to our Senior level options (Physical Geography, World Issues, Gr. 11 and 12 Law, Ancient Civilizations, West and the World, American History, and Canadian Politics). We also offer Pre AP (History and Geography) and AP courses (Human Geography and European History.) Students will develop not only their understanding of these eras and concepts, but critical and creative thinking skills as well as problem solving strategies. We aim to develop learners who will excel beyond the classroom, recognizing that our world today needs a whole new and diverse skill set to adapt to the constant change. Join us as we explore the story of the world around us.

Cooperative Education

Cooperative Education (Co-op) is a unique learning opportunity that extends classroom learning into business, industry and the community. The opportunity to experience the workplace helps students explore career options and gather information they need to make informed decisions about their post secondary destinations. Students increase their self-knowledge while developing valuable transferable skills and gain an understanding of the importance of attitude, teamwork and personal management skills in the workplace. Those students planning for the workplace destination, co-op facilitates the transition from school into work.

Student Services

Welcome to HT Student Services! Our staff work with your teen to provide academic and career counselling. Students are constantly transitioning during their secondary school experience: from elementary to secondary, from semester to semester, from intermediate to senior level, from secondary to post-secondary. These transitions require planning, research and the expertise of the Guidance Counsellor. Our job is to help in whatever way possible, and that help can come in many forms. We also help students with non-academic concerns and work closely with our Social Worker to connect students to community programs that can help.

If you have any questions or concerns about your child, please contact their Guidance Counsellor. The Department posts important information regularly; this includes information about pathways, course selection opportunities, specialty programs, mental health initiatives, volunteers and scholarship opportunities and much more!

  • Ms. Latimer: A-D
  • Mrs. Castiglione: E-K
