Can siblings share one RESP in Canada?

Yes — a family RESP allows you to name multiple beneficiaries who are all connected to the subscriber by blood or adoption (including siblings). All contributions and CESG grants go into one pooled account. When any beneficiary enrolls in a qualifying program, they can access Educational Assistance Payments from the shared pool.

What is a family RESP?

A family RESP (also called a family plan) is a single RESP account with multiple beneficiaries. All beneficiaries must be blood relatives or adopted children of the subscriber. There is a shared contribution limit ($50,000 per beneficiary across all plans) and the CESG is tracked per child but pooled in one account. All children on the plan can access the funds when they enrol in a qualifying program.

What is the difference between an individual RESP and a family RESP?

An individual RESP has one beneficiary and can have any subscriber (a grandparent can open one for a grandchild who is not related to their other beneficiaries). A family RESP has multiple beneficiaries who must all be blood relatives or adopted children of the subscriber. Family RESPs are more flexible when one child uses more or less than their share of the funds.

Can I add a new sibling to an existing family RESP?

Yes. You can add a new beneficiary to a family RESP at any time. The new beneficiary must be: (a) a blood relative or adopted child of the subscriber, and (b) under 21 years old at the time they are added (for any beneficiary added after June 4, 2004, this age restriction applies). Adding a newborn sibling at birth is common.

What happens if one child in a family RESP doesn't go to school?

The funds in the plan can simply be used by the other beneficiaries on the plan who do attend school. With a family RESP, there is no formal beneficiary change required — the other child(ren) on the plan already have access to the pooled funds. CESG grants allocated specifically to the non-attending child must be tracked; if they cannot be used by another beneficiary, they may need to be repaid.

Individual vs. Family RESP: Core Difference

Feature	Individual RESP	Family RESP
Number of beneficiaries	One	Multiple
Beneficiary relationship requirement	None — can be any child	All must be blood relatives or adopted children of subscriber
Contribution limit	$50,000 per beneficiary	$50,000 per beneficiary, tracked across all plans
CESG tracking	Per beneficiary	Per beneficiary, pooled in one account
Flexibility when one child skips school	Requires beneficiary change or closure	Other beneficiaries on plan access excess funds automatically
Ideal for	Single-child families, grandparent plans	Two or more children in the same family

How Grants Work in a Family RESP

CESG grants are tracked per beneficiary (per child’s SIN), even though the money sits in one pooled account. CRA tracks the cumulative CESG paid per child’s SIN across all their plans.

In a family RESP:

Contributions made specifically in a year are attributed to each beneficiary’s CESG tracking
When you contribute, your provider asks which beneficiary to attribute the contribution to for grant purposes
The total money in the account is pooled — there is no separate “Child A’s sub-account” and “Child B’s sub-account” from an investment perspective
When one child draws an EAP, the grant portion drawn is tracked against their cumulative CESG received

Contribution Attribution: Flexibility for Parents

In a family RESP, parents can attribute contributions strategically:

Example: You have a 10-year-old and a 2-year-old. You contribute $5,000 this year.

You can attribute $2,500 to the 10-year-old (who has fewer grant-eligible years remaining) and $2,500 to the 2-year-old
Or attribute all $5,000 to the 10-year-old as a catch-up year
Or split however maximizes grant capture

This contribution attribution flexibility is a key advantage of family RESPs over multiple individual plans.

The $50,000 Limit in a Family RESP

The $50,000 lifetime contribution limit applies per beneficiary — not per plan. If you have two siblings on one plan, the total contribution limit is $100,000 (i.e., $50,000 per child).

CRA tracks this per child SIN. Overcontributing beyond $50,000 attributed to any single beneficiary triggers the same RESP overcontribution penalties as individual plans.

Adding a New Baby to an Existing Family RESP

One of the most practical uses of a family RESP: when you have a second child, simply add them as a beneficiary to the existing plan.

Process:

Contact your RESP provider
Request to add a beneficiary
Provide the new child’s SIN and birth certificate
Begin attributing contributions to the new child to capture their CESG

Requirements for the new beneficiary:

Must be a blood relative or adopted child of the subscriber
Must be under 21 years old when added (for plans post-June 4, 2004)

This is the key flexibility advantage of a family RESP over individual plans.

In an individual RESP, if Child A has $60,000 but doesn’t go to school, the excess beyond their needs can’t just flow to Child B’s individual RESP without a formal beneficiary change and potential grant repayment.

In a family RESP, if Child A only uses $20,000 of the pooled $60,000, the remaining $40,000 is accessible to Child B without any formal change — they are already beneficiaries. The only tracking concern is CESG grant attribution, but the investment funds are fully shared.

CESG Grant Repayment Risk in Family RESPs

If a beneficiary’s CESG-attributed grant portion cannot be used by any beneficiary on the plan:

The CESG must be repaid to the government
Investment earnings on the CESG portion become an AIP (Accumulated Income Payment) subject to income tax + 20% penalty if taken in cash, or eligible for RRSP transfer

To minimize this risk, confirm that at least one beneficiary on a family RESP will likely pursue qualifying education before closing the plan.

Who Can Open a Family RESP?

Subscriber	Can use family RESP?
Parent (legal guardian)	Yes — for their biological/adopted children
Grandparent	Only if all beneficiaries are their grandchildren (blood/adopted) — some institutions may restrict this
Non-relative (aunt, family friend)	No — must be blood relatives or adopted children of subscriber

Grandparents who want to name grandchildren who are not siblings (e.g., two grandchildren who are cousins, not siblings) must open separate individual RESPs for each grandchild.
