Since October 24th, 2017, the age of the dependent child has been changed from under 19 years old to under 22 years old.
This change applies to all new applications received on or after October 24, 2017.
In the meantime, Citizenship and Immigration Canada (CIC) has implemented a temporary public policy to allow eligible dependents to be added on their parents' application or to be sponsored.
Here are the criterias to be met in order to add your child under 22 years to your PR application:
Your child was 19, 20, or 21 as of May 3, 2017 or the date your permanent residence application was made, if it was received on or after May 3, 2017 and before October 24, 2017;
You or your child had a permanent residence application that was either pending on May 3, 2017 or was received on or after May 3, 2017 and before October 24, 2017 (the child must have been previously identified as “additional family” on your application);
Child is not a spouse/common-law partner; and,
Child is not otherwise inadmissible.
If the criteria applies to your application, you may:
Add your child to your current application if your Confirmation of Permanent Residence (COPR) has not been issued yet.
Sponsor your child as a member of the family class once you have obtained permanent residence.
Please note that your dependent children may always be part of your application if they are have depended on your financial support since before they were the age of 22 and are unable to support themselves financially because of a mental or physical condition.
