Canadian chiropractors must complete at least seven years of post-secondary school. A minimum of three years in an undergraduate program at a university and then four years at an accredited chiropractic college. This means that a chiropractic student will have over 4500 hours of education, much of which is completed in a clinic while under supervision. After a student has completed their education, they then must sit and pass a stringent set of licensing exams. This is the only way that they may earn the right to practice as a Doctor of Chiropractic (DC). There are only five health professionals permitted to use the title of Doctor, chiropractors being one of them.
