Hi everyone,
I'm a third year mechanical engineering student planning on transferring to Comp Sci. The comp sci programs requires taking up to 10 complementary electives from 1st yr to 4th yr. My question is, will the courses I took from mechanical engineering count towards the complementary electives to be taken in Comp Sci? Thank you.

If they aren't Comp Sci 'required' courses, then most likely they could be counted towards your course credits as electives, double check the Comp Sci 'electives' list, and I would recommend also talking with an Academic Advisor in your faculty, they can best answer your questions for electives.
