In general, the majority of people will need a work permit to work in Canada on a temporary basis.
Temporary foreign workers who are allowed to enter and remain in Canada come:
Addressing temporary labour and skills shortages when Canadian citizens or skilled permanent residents are not available
Working in Canada for professional reasons under international agreements
The required Permit will be either a closed work permit or an open work permit. In addition to common eligibility requirements, other requirements will have to be met depending on where the application is made, regardless of the type of work permit to be applied for.
The closed work permit
Linked to a given employer, it allows the foreign national to work under specific conditions and indicated on the document issued by the immigration services, namely:
the name of the employer
The period of validity of the work permit
Etc.
In this case, the employer will have to produce a labour market impact assessment or a valid job offer number required to submit the work permit application.
The open work permit
In some specific cases, an open work permit may be issued to a foreign national to allow them to work for any employer in Canada, an exemption for employers deemed ineligible either because they are on the list of employers who have failed to comply with the conditions; or because they regularly offer nude or erotic dance activities, escort services or erotic massages.
A work permit with occupational restrictions may be issued outside Canada to allow him to work in a specific occupation because of medical or program requirements.
