To work in Canada, you typically need a work permit, which is a document that allows you to work legally in the country. In order to obtain a Canadian work permit, you must first have a job offer from a Canadian employer who is authorized to hire foreign workers. Once you have a job offer, you can apply for a work permit from Immigration, Refugees and Citizenship Canada (IRCC).

There are several types of Canadian work permits, each with their own eligibility requirements and application processes. Some of the common types of Canadian work permits include:

1. Temporary Foreign Worker Program (TFWP) Work Permit – for foreign workers who have a job offer from a Canadian employer that has received a positive Labour Market Impact Assessment (LMIA) from the Government of Canada.

2. International Mobility Program (IMP) Work Permit – for foreign workers who are exempt from the LMIA requirement under an international agreement, such as the NAFTA agreement or a youth mobility program.

3. Post-Graduation Work Permit (PGWP) – for international students who have graduated from a Canadian post-secondary institution and want to work in Canada.

4. Intra-Company Transfer Work Permit – for employees of a foreign company who are being transferred to a Canadian subsidiary, affiliate or parent company.

5. Global Talent Stream Work Permit – for high-skilled workers who have a job offer in one of the occupations identified under the Global Talent Stream.

In order to apply for a Canadian work permit, you will need to provide proof of your job offer, as well as documentation demonstrating that you meet the eligibility requirements for the specific type of work permit you are applying for. You may also need to undergo a medical examination and provide a police certificate.
