What you should know

If you want to work in Canada, you must understand the following important information:

• Your employer helps determine if you are eligible. Your employer may need to get a labour market opinion from Human Resources and Social Development Canada (HRSDC). A labour market opinion confirms that the employer can fill the job with a foreign worker. To find more information about which jobs do not require a labour market opinion, see Eligibility to apply. You can also find out more about HRSDC labour market opinions in theFrequently asked questions section.
• To work in Canada, you must meet the general requirements for entering the country and for staying here, in addition to those for getting a work permit. This means you may need a temporary resident visa. For more information on visas, see Visiting Canada.
• A work permit is not an immigration document. It does not allow you to live in Canada permanently. To live here permanently, you must qualify under an immigration category, such as skilled worker. Live–in caregivers can stay in Canada permanently if they meet certain requirements. For more information, seeImmigrating to Canada and the Live-In Caregiver Program.
• If you want your spouse or common–law partner and your dependent children to come with you to Canada, they must apply to do so.
