Personally I think it doesn't make much difference whether you take CS at McMaster or at other Universities in Canada. The key is to work hard, get a high GPA, sharp your presentation skills, and be active in all kinds of on-campus career fairs. McMaster CS has an internship program. It's a good chance for you to gain working experience. Go to Engineering Career Service for moer infomation. Engineering Career Service is located at JHE second floor.
