Visitor and Super Visa

Every country restricts the entry and exit of foreigners, sometimes allowing foreigners to come and visit for short periods of time. Canada issues a specific document known as a Tourist Visa (technically known as Temporary Resident Visa or TRV). These visas are also popularly known as Visitor Visas. Unless you are a Canadian Citizen or a Visa-Exempt National, a Visitor Visa is required to enter Canada.
You must get your TRV before appearing at your Point of Entry (POE) in to Canada. It has to be shown to officials at the POE.
Citizenship and Immigration Canada (CIC) are responsible for the issue of Canada Tourist Visas. Canada Tourist Visas can be issued for a period of up to 10 years but a person can stay for a maximum 6 months at a time.
Super Visa: Canadian citizens and/or permanent residents have another option to bring a parent or grandparent to Canada. Parents or grandparents of Canadian citizens and permanent residents may be eligible to apply for the Super Visa. The applicants cannot be inadmissible to Canada on the basis of health or security, and they may be required to meet specific conditions set forth by the visa office through which they will be applying. It is important to note that no dependents can be included in this application. Only parents or grandparents, together with their partners, may be included on an application for the Super Visa.
