Canada Dependent Children Sponsorship
Since August 2014 only dependents who are children younger than age 19 are allowed to be included in your visa application for processing other than cases where children who have various mental or physical disabilities and health conditions who automatically have no age limit. In the past children could be included up to age 22 years.
A child who is under the age of 19 and does not have a spouse or partner, is considered a dependent child. A dependent child is also referred to as a child of any age who is solely dependent on you due to physical or mental disability.
Dependent children of your own or your spouse’s children are allowed to be included in your visa application.
