The credits are considered equal by many if not all the US schools and should transfer without any difficulty. However, the pre-reqs for Canadian pharmacy is one year (general bio, chem, etc) whereas most US schools require 2-3 years of pre-reqs. UofT is also one of the biggest schools in Canada and you will have very little personal interaction with the profs of these courses, since the students will likely number around 500+. You should know which pharmacy program you want to go into, and see what they have to say about foreign credits.
