Individuals belonging to the visa-required countries and territories must apply for a visitor visa (also known as a temporary resident visa). A visitor visa is an official document attached to a passport that allows individuals to travel to Canada.
There are two kinds of Canadian visitor visas that can be availed by individuals to travel to Canada – single entry visa and multiple entry visas.
A Canadian multiple entry visa allows visitors to come and leave Canada without having to re-apply. However, each entry must not exceed six months. On the other hand, a Canadian single entry visa, as the name says, is valid only for one visit to Canada. Once you leave the geographical boundaries of Canada, except if travelling to United States, Miquelon and St. Pierre, individuals will have to apply again to travel to Canada. Both travel visa types are valid for a fixed period of time and cannot be used after they have expired. The maximum validity date for multiple entry visitor visas is up to 5 years or one month prior to the expiry date on the passport/re-entry visa, whichever is earlier. Visit Visa (TRV) is a program that is absolutely for temporary stay/residence.
