What is the difference between an employer-specific and an open work permit in Canada?

An employer-specific work permit, sometimes called a closed permit, is valid only for a specific employer, role, and usually a set location and duration. It is normally based on a Labour Market Impact Assessment (LMIA) or an LMIA-exempt offer of employment.

An open work permit is not tied to a particular employer. It lets you work for most employers in Canada, although some restrictions can apply, for example on employers who fail to meet certain conditions.

Which type you can get depends on your situation, since open work permits are available only under specific programs and circumstances.
