Yes, a Canada visitor visa can be converted to a work permit in certain cases, but it is not automatic. Visitors in Canada must apply online to Immigration, Refugees and Citizenship Canada (IRCC) before their visitor visa expires. They need a valid job offer from a Canadian employer and usually a positive Labour Market Impact Assessment (LMIA), unless exempt.
Applicants must submit supporting documents like the job offer, LMIA (if applicable), qualifications, and medical exam results. Not all visitors qualify, and sometimes applying from outside Canada is better. Consulting an immigration professional is recommended.
