With me, I didn\'t know what I wanted to major in when I graduated high school. So I went to a junior college and took my general education courses, to get them out of the way. I don\'t know if Canada has any community colleges, but if you do, then look for some class that\'s like a career exploration. It\'ll help you narrow down what you can consider as a possible major. By taking those general ed courses you can take your time to decide what you want to do with life.
THis summer you can conduct some interviews with people who are in some professions that seem to interest you. Ask them what it\'s like to work in that field and if they think it\'s satisfying. Of course, the average person changes careers at least an average of 3 times in his/her lifetime.
Well, congratulations on graduating! And good luck in finding what you want to do with life.
