Although, a froeign national requires a Labor Market Impact Assessment (LMIA) from a Canadian employer for most of the work permits. But there are certain types of Canadian work permits that are LMIA-exempt.
If a Canadian employer seeks to hire a foreign worker, they should get an LMIA in the first place. LMIA is evidence demonstrating that the employer has made sufficient efforts to hire a Canadian citizen or permanent resident for the available position which did not help them. Therefore, they are in need to hire a temporary foreign worker instead.
However, when an international applicant applies for most of the Canadian work permits, he/she is required to hold a positive LMIA and the number of the LMIA should be included in the application. But there are certain exemptions to it.
Below given are the three types of work permits in Canada:
Closed Work Permits
Open Work Permits
Closed LMIA-exempt work permits
Closed work permits are referred to the permits that enable the foreign worker to work at a particular position for a particular employer, as listed on his/her valid LMIA document.
Whereas, an open work permit allows the foreign worker to work in Canada at any position, for any employer, at any location as per his/her discretion. Because these permits are not limited to any specific employment, they do not require an LMIA. Also the applicant does not need any job offer at the time of application of an open work permit.
Closed-work permits to a certain extent are a mix of the two. These enable the foreign national to work in Canada for a particular employer at a specific designation but without any LMIA.
