Business visitors are different from business people as defined in Free Trade Agreements. Business people come to do work in Canada under a free trade agreement like NAFTA (North American Free Trade Agreement) and few other trade agreements. Under NAFTA all business visitors coming in to do after-sales services for work periods longer than 2 days must be documented in a Visitor Record. This requirement is for facilitation and a control measure.
Despite having a valid TRV or eTA, a CBSA officer at the Canadian Port of Entry has all right to refuse admission to any foreign traveller if after examination of documents or initial interview, he is of the view that there is a difference between what is being presented now from the one which was presented at the time of seeking visa. The most important consideration is whether the person will leave Canada at the expiry of his visitor status or not. So all visitors must demonstrate that the purpose of their visit to Canada is of a temporary nature and they are here for the same reason as they have mentioned at time of their application.
