Bachelor's degree [SEP] Canada
This last category included graduate-entry degrees titled as if they were doctorates, such as MD, JD and DDS degrees – despite their names, these are considered bachelor's degrees. Bachelor's degrees may take either three or four years to complete and are awarded by colleges and universities. In many universities and colleges bachelor's degrees are differentiated either as bachelor's or as honours bachelor's degrees. The term "honours" is an academic distinction, which indicates that students must achieve their bachelor's degree with a sufficiently high overall grade point average; in addition, some programs may require more education than non-honours programs. The honours degrees are sometimes designated with the abbreviation in brackets of '(Hon(s))'.
