The MCCEE includes more basic medical science questions as it evaluates the whole degree, rather than the MCCQE, a qualifying exam. Remember Mika, as it stands now, it would still be next to impossible to come to Canada to do a residency. Even after passing the MCCEE, you would, for example in Ontario, have to apply to OIMG, get accepted, do 1 year at an Ontario med. school, then you would get Ontario Ministry sponsorhip to write MCCQE, and enter a limited number of specialties that are in demand. To add insult to injury, you're charged about 5 grand tuition per year of your residency. Until the system becomes saner and fairer, the best route is to enter an American residency, complete it, then write the corresponding CCFP or RCPC or RCSC examination. Even then, an American residency may not be enough to qualify for the exam. For example, Internal med is 3 yrs in US but 4 yrs in Canada, so you would need another year of residency to be RCPC eligible. The duration of surgery residencies are the same, and family is an extra year in US, so the only difficulties would be in Internal Med and its subspecialties, Opthalmology, Anasthesiology and PM&R (I think) which all are a year longer in Canada.
I think that's why people who go elsewhere for med school never actually return!
