Canadian citizens and permanent residents have Super Visa option to bring a parent or grandparent to Canada. The Super Visa Program allows parents and grandparents to come to Canada as long-term visitors on a multi-entry visa that remains valid for up to 10 years.
The extension of a Canadian temporary resident visa is called Visitor Record, which is used to maintain status in Canada and cannot be used for entry and exit (except going to or from the United States).
Visitor Visa or Temporary Resident Visa is an official travel document required to enter Canada as a visitor. The Visitor Visa is usually approved until the validity of the applicant’s passport, but the person can only stay in Canada for at most 6 months upon their entry.
