The Canadian Free Trade Agreement only applies to workers that have already been certified by a province/territory in Canada. However, once internationally trained/educated workers have been certified in a province or territory they are recognized as qualified to work in the same occupation in another province or territory, and should therefore not be required to undergo any additional material requirements such as having qualifications reassessed, taking exams, doing additional training, gaining additional work experience or undergoing additional assessments unless an exception has been posted.
