What high school cles do I need to be a psychologist in Canada?

The specific courses you take in high school are not as important as maintaining a good grade point average and doing well on standardized tests so that you can get into a good University. Your goal should be to get into a University that allows you to complete an honours degree in psychology. The hardest part to becoming a psychologist is getting into graduate school. It will be easier to accomplish if you have a strong undergraduate degree. Good luck.
