Hi there,
So CAPS at UBC isn't a unique program. It's a program made up of Physiology and Cell Biology courses. You can find similar programs at any large Ontario school (Queens, Western, UofT, Waterloo, uOttawa, etc.).
I would guess the most similar program would be Western Med Sci, in their Honours Specialization in Physiology & Pharmacology. However, like CAPS at UBC, it is VERY difficult to get into this program. You need a 89% average in 2nd year university to get in.
Good luck with your search for a university program.
