Life Sciences at Guelph
Not directly. At University of Guelph you apply to Bachelor of Science (BSc) Honours (GZ), then choose life sciences on the OUAC application itself. Guelph's Honours BSc majors all share code GZ, and you name your major when you apply. First year is common across the majors, so Guelph says switching afterwards is straightforward.
