Seeking Employment
If you are in Canada:
+ As a dependent of a person who has valid student or employment authorization
+ Or on a visitor visa
+ Or as a refugee claimant awaiting determination of your claim

...then you may be eligible to work in Canada. In special cases, if you have a student authorization, you may be eligible for employment authorization (employment is considered integral to your studies, employment starts within 60 days of final marks being issued, etc.). Contact Citizenship and Immigration Canada (CIC) to see if you are eligible to work in Canada. If you are eligible to extend your stay, you may apply for jobs. If an employer agrees to hire you for limited-term employment, you should obtain an official letter for the job offer with all the necessary information (such as job description, wages, location, etc.). You will need this letter to apply for work authorization. Contact Citizenship and Immigration Canada for more informationor to obtain the complete application form.

It is the employer's responsibility to contact Human Resources Development Canada (HRDC) and give them details about your job offer. HRDC will make an informed opinion on the possibilities and benefits of granting you employment. HRDC will then contact CIC and inform the immigration officer of their opinion. After considering the applicant and if the job offer is validated by HRDC, CIC may approve your application. If your application is approved, you will be sent Employment authorization which will allow you to stay and work in Canada. Employment authorization will change the conditions of your stay and extend your period of authorized stay in Canada.

Before the end of your authorized stay, you must reapply for another extension. You should reapply at least three weeks before expiry of your stay. People with employment authorization to work in Canada must apply for new employment authorization before they can change jobs.
