With regard to the distinction between a work visitor visa and a Canadian work permit, Canada provides an explanation.
Visitor visas for Canadian-based businesses.
Visitors to Canada are required to obtain a visiting visa in order to enter the country, regardless of the activities they intend to engage in while they are there. This is the case unless they are excluded from the requirement. Visitors who are coming to Canada for business purposes are required to submit an application for a temporary resident visa (TRV), sometimes known as a visiting visa.An individual who travels to Canada for the purpose of engaging in international business activities but does not directly enter the Canadian labor market is referred to as a business traveler.
The difference between a work visitor visa and a Canadian work permit.
It is important to highlight the distinction between a Canadian work permit and a business visitor visa. As a business guest, you are not permitted to participate in the labor force in Canada. The purpose of business visitor visas is to enable short-term stays for the purpose of conducting business activities such as attending industry conferences, seeing sites, or receiving training. You must obtain an employment permit in the event that your employer transfers you to Canada or if you work for a Canadian company in any other capacity.
For the purpose of looking for work in Canada, you are permitted to visit the country as a visitor.
However, if you do not have a work permit, you are not permitted to lawfully work in Canada. In the event that you are in Canada on a visiting visa and receive a job offer from a Canadian company, you are required to submit an application for a work permit before you can begin an employment relationship. As a result of the fact that your application must be processed by the Canadian visa office that is responsible for the nation in which you reside or are a citizen, it is possible that you will be obliged to leave Canada while your application is being processed. You are, nevertheless, permitted to legally remain in Canada for the duration of the validity of your visiting visa.
