Assuming you are a Canadian citizen / PR:
It
may be possible for
family physicians.
The CCFP designation
may be granted without examination by the CFPC to those physicians who have met all of the following:
1) successfully graduated from accredited postgraduate training in family medicine in a jurisdiction where the standards for accreditation of postgraduate family medicine training and the criteria for certification are judged comparable and acceptable to the CFPC;
2) hold certification in family medicine in that jurisdiction;
3) met all other requirements for Certification in the CFPC;
4)
met all other requirements for licensure and apply for or are granted registration to practice in a Canadian province or territory
Approved jurisdictions include:
United States of America: Graduates of family medicine residency training programs that have been accredited by the Accreditation Council for Graduate Medical Education (ACGME) and who also are Diplomats of the American Board of Family Medicine (ABFM)
Australia: Graduates of Australian General Practice Vocational Training programs that have been accredited by the Australian Medical Council (AMC) and meet the standards of the Royal Australian College of General Practitioners (RACGP) and who also hold Fellowship in the Royal Australian College of General Practitioners (FRACGP)
Note: These programs vary from Canadian programs in that training in intrapartum care is not compulsory.
Ireland: Graduates of general practice vocational training schemes that have been accredited by Irish College of General Practitioners (ICGP) and who also hold Membership in the Irish College of General Practitioners (MICGP)

As for
specialists, depending on your specialty you may be eligible to have your training assessed by the Royal College in Canada on the basis of holding fellowship with one of the
approved colleges within the Australian Medical Council. The Royal College reserve the right not to approve your training. If they do, then you are eligible to sit the Royal College exams in your specialty. These are quite challenging for IMGs, I understand, but if you can pass then you can be certified by the Royal College.
Note that each province controls licensing to practice medicine within the province, and the individual provincial of College of Physicians and Surgeons may or may not accept your credentials on an individual basis. The CFPC and the FRCPC do not confer license to practice. It would be very wise to contact the College of Physicians and Surgeons of the province you're interested in practicing in, and putting this question to them.
