If you are eligible to be considered a Business Visitor, you do not need a work permit to come to Canada. A Business Visitor is a foreign national who comes to Canada to conduct business activities. Since they do not enter the labour market on their trip, no work permit is required.
IT workers may be considered Business Visitors in the following circumstances:
1) After-sales service takes place during cross-border transactions. These situations arise when a Canadian company has purchased a product from a foreign company and the foreign company must provide service or do maintenance work on the product. Foreign tech workers may be required to travel to Canada to do this work.
2) Another category of Business Visitors applies to those who are entering Canada to speak at a seminar or to participate in a workshop.
3) Another category of Business Visitor that is often seen from the tech field are those who enter Canada to receive training at a Canadian branch of a multinational company.
