If you are interested in working temporarily in Canada you must know some information:
Overview
Every year, over 90,000 foreign workers enter Canada to work temporarily to help Canadian employers address skill shortages. Citizenship and Immigration Canada (CIC) and Human Resources and Social Development Canada (HRSDC) ensure that these workers will support economic growth in Canada and create more opportunities for all Canadian job seekers.

In almost all cases, you must have a valid work permit to work in Canada.

These steps must be followed before you apply for a work permit:

  1.. An employer must first offer you a job.

  2.. HRSDC must normally provide a positive labour market opinion of your job offer. However, some types of work are exempt from this process.

  3.. After HRSDC confirms that a foreign worker may fill the job, you apply to CIC for your work permit.
To get a work permit, you must fill out an Application for Work Permit.

A work permit is issued if the application is approved.

You cannot immigrate with a work permit.

If you want to come and live in Canada as a permanent resident based on your work skills or experience, see if you qualify for the Skilled Worker Program.
