IRCC has changed the definition of the age of dependants. Now it's "under 22".

Immigration, Refugees and Citizenship Canada has changed the definition of the age of dependants from “under 19” to “under 22”. This new rule will help more applicants and their families stay together. This change applies to all new applications received by IRCC on October 24, 2017 or after.

The Government has introduced a Public Policy that would allow for the addition or sponsorship of some children whose parents had existing applications in process on May 3, 2017, or who have applied since that time.

We suggest all permanent residence applicants, who wish to add or sponsor a child under the public policy, to check IRCC Web Tool to see if their child qualifies. If you have any questions about these new changes please contact us.
