The Super Visa is a temporary visa given to parents and grandparents of a Canadian citizen or permanent residents of Canada, which enable them to come to Canada as a visitor for a stay of up to five consecutive years from their initial entry, without the need of having to renew their status.  It’s a multi-entry visa that provides multiple entries for a period of up to 10 years. 

You cannot include dependents in this application. They are not eligible for a super visa. They can still apply for a visitor visa to visit Canada for up to 6 months.
