The process of getting a work permit in Canada varies with the type of work permit an applicant is applying for. There are generally two types of work permits: open work permits and closed work permits. The open work permit is issued to international students who are studying in a post-secondary program in a designated educational institution in Canada or someone who has applied for a permanent residence in Canada. It can also be provided to a family member of someone who is a permanent resident in Canada. There are several other types of candidates who can apply for an open work permit.
A closed work permit on the other hand is offered to a foreign national with a job offer from a registered Canadian employer. In this case, a proper LMIA is required for obtaining a work permit.
Also, international students can automatically get part-time work permits under the authorisation of their study permits.
