Canada's provinces and territories are responsible for overseeing all aspects of education and training, including apprenticeships in skilled trades. They often determine the criteria and standards for evaluating and recognizing foreign qualifications for certain trades.
Your training, work experience, and abilities must be evaluated by the regulatory body that oversees trades in your province or territory in order for them to determine if you qualify to take an exam to get certified.
You may require an employer in Canada to provide you with training and work experience before you are authorized to pass the certification test, therefore you will likely need to travel there physically to write the exam in order to receive a certificate of qualification.
