Canadian citizens and permanent residents can sponsor their dependent children for permanent residence in Canada. Dependent children are those under 22 years old, or over 22 if they are financially dependent due to a disability. The sponsorship process requires proving the parent-child relationship and meeting income requirements to support the child. Sponsorship can apply whether the child is outside Canada or already living in Canada on a temporary status. Once approved, dependent children can reunite with their family in Canada and enjoy permanent residency benefits.
