Dependent Children Eligibility Canada 2026

Check which of your children qualify as dependents on your Canadian PR application using the lock-in date rule and 22+ exceptions.

Key Takeaways

IRCC uses the under-22 rule for dependent children since October 24, 2017 — the previous under-19 rule no longer applies.
Children aged 22 or older qualify only if they have depended substantially on a parent since before age 22 due to a physical or mental condition.
Being married or in a common-law relationship disqualifies a child from dependency status regardless of age.
The full-time student exception from pre-2017 rules has been removed — students 22+ no longer qualify solely because they are in school.
The lock-in date is typically the date IRCC issued your ITA or the date you submitted your PR application.

Dependent Children Eligibility Checker

IRCC uses a specific definition of "dependent child" for permanent residence applications. Since October 24, 2017, a dependent child is someone who is under 22 years old on the application lock-in date and is not a spouse or common-law partner. An exception allows children aged 22 or older to qualify if they have been financially dependent on a parent since before age 22 due to a physical or mental condition.

This checker evaluates each of your children against IRCC's dependent-child definition using your application lock-in date. It reports per-child verdicts (dependent or not) and explains the age calculation and any applicable exceptions. The lock-in date is typically the date IRCC issued your Invitation to Apply or the date you submitted your PR application — ask your representative if unsure.

How It Works

1. Enter your application lock-in date (YYYY-MM-DD). This is the reference date IRCC uses to assess each child's age.

2. Add each child with their birth date.

3. For each child, indicate whether they are married or in a common-law relationship (disqualifies regardless of age), whether they have been a full-time student since before age 22 (no longer an exception after 2017), and whether they have a physical or mental condition causing financial dependence.

4. The checker computes age on the lock-in date and applies the rules to determine dependency.

The Lock-In Date Rule

IRCC assesses each child's age as of the "lock-in date" — the reference date that preserves dependency status throughout the application process. For Express Entry applicants, this is the date IRCC issued the Invitation to Apply (ITA). For paper-based applications, this is the date IRCC received the complete PR application.

The lock-in date is important because a child who is 21 when you apply may turn 22 during processing. As long as the child was under 22 on the lock-in date, they are treated as a dependent throughout the application, even if processing takes several years.

The 22+ Medical Exception

An adult child (22 or older) may still qualify as a dependent if two conditions are met: (1) they have substantially depended on the financial support of a parent continuously since before they turned 22, AND (2) they are unable to be financially self-supporting due to a physical or mental condition.

This exception is narrow. IRCC requires medical documentation of the condition, evidence of continuous financial dependence (not just current dependence), and proof that the dependence began before age 22. Children who are financially dependent for other reasons (unemployment, education, career gap) do not qualify.

What Was the Pre-2017 Rule

Before October 24, 2017, IRCC used the under-19 rule: a dependent child was someone under 19 on the lock-in date, with an exception for full-time students up to age 25. The 2017 reforms raised the age to 22 and eliminated the student exception — students 22+ no longer qualify solely because they are enrolled in school. The medical-condition exception was retained.

If you applied before October 24, 2017, the old rules may still apply to your existing application. For new applications, the under-22 rule is the only applicable standard.

Key Facts

Dependent children must be under 22 on the application lock-in date and not a spouse or common-law partner.
The under-22 rule has applied since October 24, 2017 — the previous under-19 rule was replaced.
The only exception for children 22+ is a physical or mental condition causing continuous financial dependence since before age 22.
The full-time student exception was removed in 2017 and no longer applies.
The lock-in date is typically the date of the Invitation to Apply (Express Entry) or the application receipt date (paper applications).

FAQ

What is the lock-in date for my application?

For Express Entry applications, the lock-in date is the date IRCC issued your Invitation to Apply (ITA). For paper-based family class and other applications, it is the date IRCC received your complete PR application. Always use the earlier of any applicable dates.

My child was 21 when I applied but is now 23 — are they still dependent?

Yes. As long as the child was under 22 on the lock-in date, they remain a dependent throughout the entire application process, even if they turn 22 or older during IRCC processing. The lock-in date freezes their dependency status.

My adult child has a mental-health condition and is 24 years old — does the exception apply?

Possibly. The exception requires two things: first, the condition caused financial dependence before they turned 22, and second, the dependence has been continuous since then. You need medical documentation and evidence of continuous support. Talk to an authorized immigration consultant or lawyer if you are relying on this exception.

What about my 23-year-old who is in university full-time?

Full-time student status no longer qualifies a child 22 or older as a dependent. The 2017 rules removed this exception. Your 23-year-old can still immigrate to Canada separately (as a student, worker, or through their own PR application), but they cannot be included in your current PR application as a dependent.

Are common-law partners treated the same as married spouses?

Yes — for the purposes of dependent-child rules, common-law partnerships disqualify a child from dependency status the same way marriage does. IRCC defines common-law as having lived together continuously for at least 12 months.
