While the Canadian Super Visa falls under the category of visitor visa, it is entirely designed for parents and grandparents of Canadian citizens and permanent residents.
The main distinction between the two visas is the duration of the authorized stay in Canada. A visitor visa only allows for a stay of up to 6 months at a time. With a Super Visa, eligible parents and grandparents can stay in Canada and visit family for 5 years at a time.
