Immigration Refugee and Citizenship Canada (IRCC) will re-open the parents and grandparents permanent residence sponsorship in January 2018.
Who is eligible to sponsor a parent or grandparent
You can sponsor your parents and grandparents if you’re 18 years of age or older, living in Canada and are a:
Canadian citizen or
person registered in Canada as an Indian under the Canadian Indian Act or
permanent resident of Canada
If you live in Quebec, you must also meet Quebec’s immigration sponsorship requirements after we approve you as a sponsor.
The Application Process
You must fill out a short Interest to sponsor form online. This form will become available from 12noon EST on January 2nd, 2018 - February 1st 2018.
After February 1, IRCC will randomly select potential sponsors and invite them to apply.
If you are invited to apply, you must submit a complete application before the deadline specified on your invitation.
If you are not invited in 2018, you may try again in 2019.
If you want your parent or grandparent to visit you in Canada, you can apply for a super visa.
