Yes, you can. We recommend that you contact the professional or trade association governing your occupation in your home country to determine if it has any affiliation with a similar association in Canada. You might also want to check with the Canadian consul or consulate in your country to obtain information about your occupation and possible licensing requirements, certification or registration as well as the procedure for obtaining an assessment.
Most Canadian diplomatic offices have a publication entitled National Occupational Classification that might help. Be forewarned that it may take you months if not years to obtain the additional training and pass the exams required to obtain a licence or certificate to practise in Canada.
If you are in a “non-regulated” occupation, on the other hand, you don’t need a licence to practise it although there may be an association or professional body related to your profession that offers voluntary membership, training and support services.
The Canadian Information Centre for International Credentials (CICIC) can help you obtain the credentials and accreditation you need to find work in your occupational field. The CICIC does not assess anyone’s qualifications or grant certification, but does provide guidance from its vast library of contacts in education, the professions and skilled labour.
