It is illegal to work in Canada with a tourist visa. If discovered, you will be deported and permanently banned from re-entering Canada. Those wishing to work in Canada should apply for a Canadian work visa.
The legal way to work in Canada is:
You must find an employer in Canada who is willing to hire and sponsor you. After the employer applies for and obtains a Labour Market Opinion (LMO) from the Canadian Human Resources Department, you must return to your home country to apply for a work visa at the Canadian visa center before entering Canada.
Application materials:
After receiving a job offer from a Canadian company, the applicant must first apply for a visa at the Canadian embassy in their home country. When applying for the visa, you must bring the job offer from the Canadian company and documents proving your suitability for the job. In addition to the job offer, prepare the following materials:
(1) Completed work visa application form, agent information form, and work visa application document checklist.
