Determine your eligibility
To apply for the parent and grandparent super visa, you must:
be the parent or grandparent of a Canadian citizen or a permanent resident of Canada,
be allowed to enter Canada and
meet certain other conditions.
Note: You cannot include dependants in this application. Only your spouse or common-law partner can come with you under this visa.
Visa officers consider several things before they decide if you can come to Canada. You must be a real visitor to Canada who will leave by choice at the end of your visit. A visa officer will look at these things when you apply:
your ties to your home country,
the purpose of your visit,
your family and finances,
the overall economic and political stability of your home country, and
an invitation from a Canadian host.
You must also:
prove that your child or grandchild in Canada meets a minimum income threshold,
provide a written statement from that child or grandchild that he or she will give you financial support,
have valid Canadian medical insurance coverage for at least one year and
have an immigration medical exam.

How does the parent and grandparent super visa differ from a visitor visa?
Currently, most visitors to Canada may visit for up to six months when they first enter Canada. Visitors who wish to stay longer must apply for an extension, and pay a new fee.
With the parent and grandparent super visa, eligible parents and grandparents can visit family in Canada for up to two years without the need to renew their status.
The Super Visa is a multi-entry visa that provides multiple entries for a period up to 10 years. The key difference is that the Super Visa allows an individual to stay for up to two years on initial entry into Canada, while a 10-year multiple entry visa would only have a status period for each entry of six months only.
There are also specific requirements that you must meet to be able to get a super visa. See the CIC website for who can apply for a grandparent super visa or Who is eligible for a parent and grandparent super visa?
