Grandparent RESP Canada 2026 — How Grandparents Can Open & Contribute

Can Grandparents Open an RESP?

Yes — absolutely. Any Canadian resident can open an RESP for a child. Grandparents, aunts, uncles, family friends — the subscriber (account holder) does not need to be the child's parent or legal guardian. This makes grandparent RESPs one of the most impactful financial gifts a grandparent can give.

A grandparent who opens an RESP for a grandchild at birth and contributes $2,500/year will accumulate up to $7,200 in CESG over 18 years — the same grants available to parents — plus decades of tax-sheltered compound growth.

Key point: Grandparents opening a separate RESP must coordinate with parents to ensure combined contributions from all sources don't exceed the $50,000 lifetime limit per child. This is the most important rule for grandparent RESPs.

How to Open a Grandparent RESP

Get the grandchild's SIN — ask the parents for the child's Social Insurance Number
Choose an RESP provider — any bank, credit union, or online brokerage (Wealthsimple, Questrade)
Open an individual RESP — as the subscriber, you'll need your own SIN and the child's SIN and date of birth
Apply for CESG — done automatically. The grandparent as subscriber receives the CESG in the account
Coordinate with parents — track combined contributions across all RESPs for the child to stay under $50,000

Critical coordination required: If parents already have an RESP, grandparents must know the current balance and planned future contributions before contributing. The $50,000 lifetime cap is per child, not per account. Exceeding it triggers a 1%/month penalty on the excess.

CESG on Grandparent RESP Contributions

The CESG is paid on the first $2,500 contributed per year per beneficiary — from all sources combined. If a parent already contributes $2,500 to their own RESP for the child, additional grandparent contributions that year earn no additional CESG (the $2,500 limit has already been met).

Parent Contribution	Grandparent Contribution	CESG Earned (combined)
$2,500/yr	$0	$500 (parents' RESP)
$0	$2,500/yr	$500 (grandparents' RESP)
$1,000/yr	$1,500/yr	$500 (split between accounts)
$2,500/yr	$2,500/yr	$500 max (no extra CESG on grandparent contribution)

The most common strategy: parents contribute $2,500/year to capture the full CESG, and grandparents contribute additional amounts (lump sums or regular amounts) to top up the account — with no additional CESG but still benefiting from tax-sheltered growth.

Tax Implications for Grandparent RESPs

When the grandchild withdraws the RESP for education (EAP), the income is taxed in the student's hands — not the grandparent's. This is the same treatment as a parent-owned RESP and is highly tax-efficient since students typically have little other income.

Important: The subscriber (grandparent) controls the RESP. When the child withdraws for education, the EAP goes to the student (taxed in student's hands). If the RESP isn't used for education, the accumulated income reverts to the subscriber (grandparent) — subject to the AIP rules (marginal rate + 20% penalty, unless rolled to grandparent's RRSP).

Social Assistance Claw-Back Consideration

If the grandchild is receiving social assistance or student loans, RESP withdrawals (EAPs) may affect their benefit amounts. This varies by province and program. Consider timing withdrawals carefully and discuss with a financial advisor if the grandchild receives means-tested benefits.

Transfer of Control to Parents

A grandparent who opens an RESP can transfer subscriber rights to the parents. This is often done when grandparents are elderly or want the parents to take over management. Transferring subscriber rights requires paperwork with the RESP provider and does not affect the grants or tax treatment of the account.

Alternatively, grandparents can name a successor subscriber — typically a parent — who automatically takes over the account if the grandparent passes away.

Should Grandparents Open a Separate RESP or Contribute to Parents' RESP?

Option	Pros	Cons
Grandparents open own RESP	Grandparents maintain control; can name successor subscriber	Requires coordination to avoid $50K over-contribution; more accounts to track
Grandparents contribute to parents' RESP	Simpler; one account to track; parents manage investments	Grandparents lose direct control of funds

For most families, having grandparents contribute directly to the parents' existing RESP is simpler. The parents track one account, CESG is optimized by the parents, and there's no risk of inadvertent over-contributions across multiple accounts.

Grandparents who want direct control (e.g., to ensure funds are only used for education, or to maintain flexibility if family circumstances change) should open their own individual RESP.

Estate Planning with Grandparent RESPs

Grandparent RESPs have useful estate planning features:

Successor subscriber: Designate a parent as successor so the RESP transfers seamlessly without going through the estate
Named in will: The RESP itself doesn't transfer via will — designating a successor subscriber is the correct mechanism
If no successor: The estate of the grandparent becomes the subscriber; the executor must deal with the RESP as part of estate administration

Grandparents with RESPs should always designate a successor subscriber (typically a parent) to ensure smooth transfer of the account.

FAQs

Can a grandparent open an RESP without the parents' knowledge? +

Technically yes, but it's not advisable. Without coordination, combined contributions could exceed the $50,000 lifetime limit, triggering a 1%/month over-contribution penalty. Always inform the parents before opening a grandparent RESP.

Does the grandparent get the CESG? +

The CESG is deposited into the RESP account — which the grandparent controls as subscriber. The grants belong to the child's education fund, not to the grandparent personally.

What happens to the grandparent's RESP if they pass away? +

If a successor subscriber has been designated, the account transfers to them automatically. Without a successor, the estate handles the account. Designating a successor subscriber (usually a parent) is strongly recommended when grandparents open an RESP.

Can grandparents contribute to both their own RESP and the parents' RESP? +

Yes, but all contributions to all RESPs for that child combined cannot exceed $50,000 lifetime. Track the running total across all accounts carefully.
