Asif is visiting Canada on a six-month visitor visa. He is very well trained in computer software programming and has decided he wants to help people in Calgary where he is visiting.

He has set up a web-site where he is offering to help people with computer security problems. He is prepared to help online, at their home or place of business, or have them bring in their computer or tablet where he is staying on his visit.

He has decided he does not want to be paid but he hopes to make good business and customer contacts for when he returns to the Middle East.

Asif believes he does not need a work permit to do . Is he right? What are the issues he should consider?
