You usually need a work permit to work in Canada. In some cases, you can work without a permit or job offer in Canada. If you need a work permit, you may be eligible for Open or Closed Work permit.

• employer-specific work permit (closed work permit)
An employer-specific work permit allows you to work according to the conditions on your work permit, which include:
-the name of the employer you can work for
-how long you can work
-the location where you can work (if applicable)

• open work permit
An open work permit allows you to work for any employer in Canada, except for an employer:
-who is listed as ineligible on the list of employers who have failed to comply with the conditions or
-who regularly offers striptease, erotic dance, escort services, or erotic massages

You can only get an open work permit in specific situations.
