RESP Catch-Up: How Much CESG Grant You Can Still Get by Age
If you started an RESP late, or never started one, the government grant you missed is not all gone. Unused grant room carries forward, but only $1,000 of it can be claimed each year, so your child’s age decides how much you can still collect.

This guide shows the catch-up rules, the most you can still get at each age, and the traps that cost families grant money.
The short answer
The Canada Education Savings Grant (CESG) pays 20% on RESP contributions. Every child born since 2007 builds $500 of grant room a year from birth, whether or not an RESP exists, and you can claim up to $1,000 a year by contributing $5,000 until the room is used. If you start in the year your child turns 10 or earlier, you can still collect the full $7,200 lifetime maximum. Start a year later and the ceiling falls to $7,000, then by another $1,000 for each year after that.
The rules come from Employment and Social Development Canada (ESDC), which runs the grant, and the Canada Revenue Agency (CRA). The numbers below cover the Basic CESG, which every eligible child gets. Lower-income families can get extra, explained further down.
How CESG grant room works
The Basic CESG is 20% of the first $2,500 you contribute each year, so it is worth up to $500 a year, according to Canada.ca. The lifetime limit is $7,200 per child.
The part many parents miss is grant room. ESDC’s rules for RESP providers say unused Basic CESG accumulates for each child until December 31 of the year they turn 17, “even if they are not a beneficiary” of an RESP. For children born in 2007 or later, room starts in the year of birth, at $500 a year.
When you have unused room, the grant applies to up to $5,000 of contributions in a year instead of $2,500. That doubles the yearly maximum to $1,000. You can repeat this every year until the room is used up.
Why the $7,200 cap changes the math
A child earns room for 18 calendar years, from birth to age 17. At $500 a year, that adds up to $9,000 of room. But the lifetime cap is $7,200, so no family can use all of it. That gap is what gives late starters some slack.
Someone who contributes $2,500 every year from birth hits the cap partway through the year the child turns 14. They contribute $2,500 for 14 years and $1,000 in the 15th, for $36,000 in total. A late starter needs the same $36,000, just packed into fewer years.
How much grant you can still get, by age
We modelled the most Basic CESG a family can still collect based on the child’s age in the first year they contribute. The model assumes the child was born in 2007 or later, has never received CESG, and that you contribute enough each year to claim the full amount allowed.
| Child’s age in your first contribution year | Most Basic CESG you can still get | Total you need to contribute | Grant out of reach |
|---|---|---|---|
| From birth (age 0) | $7,200 | $36,000 | $0 |
| Age 5 | $7,200 | $36,000 | $0 |
| Age 10 | $7,200 | $36,000 | $0 |
| Age 11 | $7,000 | $35,000 | $200 |
| Age 12 | $6,000 | $30,000 | $1,200 |
| Age 13 | $5,000 | $25,000 | $2,200 |
| Age 14 | $4,000 | $20,000 | $3,200 |
| Age 15 | $3,000 | $15,000 | $4,200 |
| Age 16 or 17, nothing saved before | $0 | $0 | $7,200 |
Gizly calculation using ESDC and CRA rules checked October 24, 2026. Basic CESG only; the Additional CESG for lower and middle incomes is not included. Ages 16 and 17 assume no contributions were made before.
The cut-off at age 10 comes from the $1,000 annual limit. From age 10 there are eight contribution years left (ages 10 to 17). Seven years at $1,000 plus $200 in the last one reaches $7,200. Start at 11 and only seven years remain, so $7,000 is the ceiling. After that, every year you wait removes another $1,000.
The drop at 16 is not gradual. It is a cliff, because of a separate eligibility rule covered below.
A worked example: a child born in 2016
Say your child was born in 2016 and turns 10 this year. You have never opened an RESP. Their grant room as of 2026 is $5,500: $500 for each year from 2016 through 2026.
If you contribute $5,000 before December 31, 2026, you get $1,000 of grant. Repeat that each year and here is how it plays out:
| Year | Child’s age | Contribution | Basic CESG | Total CESG so far |
|---|---|---|---|---|
| 2026 | 10 | $5,000 | $1,000 | $1,000 |
| 2027 | 11 | $5,000 | $1,000 | $2,000 |
| 2028 | 12 | $5,000 | $1,000 | $3,000 |
| 2029 | 13 | $5,000 | $1,000 | $4,000 |
| 2030 | 14 | $5,000 | $1,000 | $5,000 |
| 2031 | 15 | $5,000 | $1,000 | $6,000 |
| 2032 | 16 | $5,000 | $1,000 | $7,000 |
| 2033 | 17 | $1,000 | $200 | $7,200 |
Hypothetical example. Assumes contributions are made by December 31 each year and the child stays eligible. Investment growth is not included.
You reach the full $7,200 with $36,000 of contributions, the same total as a family that started at birth. The difference is cash flow: $5,000 a year instead of $2,500.
If this same family waits until 2027, the child is 11 and the most they can get is $7,000. Wait until 2028 and it is $6,000. Each delay is a permanent loss, because room expires at the end of the year the child turns 17.
The traps that cost families grant money
Putting in a lump sum
The grant is calculated year by year. A big contribution in one year still only earns 20% on $5,000 at most. ESDC’s own example shows a family that contributed $6,000 in one year, got the $1,000 maximum, then contributed nothing the next year and got no grant that year. The extra $1,000 earned nothing. What carries forward is room, not contributions.
Starting at 16 or 17
The CESG is paid until the end of the year a child turns 17, but for ages 16 and 17 a condition applies. According to ESDC, the RESP must have met one of these by the end of the year the child turned 15:
- at least $2,000 contributed and not withdrawn, or
- at least $100 contributed and not withdrawn in any four years.
If you are catching up for a 15-year-old, contribute at least $2,000 before December 31 of that year. A $5,000 contribution meets the test and claims $1,000 at the same time.
Missing the December 31 deadline
The grant is counted by calendar year. A contribution made on January 2 counts for the new year, not the one that just ended. For a child aged 11 or older, a skipped year is a lost $1,000, because there are no longer enough years left to use all the room.
Forgetting the Additional CESG does not carry forward
For 2026, families with adjusted family net income under $58,523 get an extra 20% on the first $500 contributed each year, and families from $58,523 to $117,045 get an extra 10%, according to Canada.ca. This extra grant cannot be carried forward, so missed years are gone. It also counts toward the same $7,200 lifetime cap.
The $50,000 contribution limit
The CRA sets a lifetime contribution limit of $50,000 per child across all RESPs, with no annual limit. Going over it triggers a tax of 1% per month on the excess. A catch-up plan of $36,000 fits well under the limit, but check if grandparents also contribute.
Before you commit to $5,000 a year
Catching up is free money, but it locks cash into an account with conditions. Weigh these first.
- The grant can go backIf your child does not pursue post-secondary education, the CESG goes to a sibling with room or back to the government.
- Room runs out at 17You do not need to catch up all at once. You only need to use the room before the end of the year your child turns 17.
- A partial catch-up still countsIf $5,000 is too much, $3,500 earns $700. Any amount over $2,500 uses some carried-forward room.
Low income? Check the Canada Learning Bond too
The Canada Learning Bond (CLB) is separate from the CESG and needs no contribution from you. It pays $500 for the first eligible year and $100 for each later eligible year up to age 15, to a lifetime maximum of $2,000, according to Canada.ca. Eligibility is based on the primary caregiver’s adjusted family income, up to $58,523 for a family with one to three children from July 2026 to June 2027. The primary caregiver can request it until the day before the child turns 18.
For other income-tested payments, see our guide to government benefits in Canada.
How to catch up, step by step
- Get your child a Social Insurance Number. You must give the beneficiary’s SIN to the RESP provider.
- Work out the room. For a child born in 2007 or later, multiply $500 by the number of calendar years from birth through this year, then subtract any CESG already paid.
- Open an RESP and ask about grants. Tell the provider you want the CESG and, if you may qualify, the Additional CESG and Canada Learning Bond.
- Contribute up to $5,000 before December 31. That claims the $1,000 yearly maximum while you have room.
- Repeat each year, then step down. When the carried-forward room is gone, $2,500 a year claims the $500 that is added each year.
- Hit $2,000 by the end of age 15. This keeps the grant flowing at 16 and 17.
Where you hold the money inside the RESP is a separate decision. For a comparison of rates on cash and guaranteed options, see our GIC rates table, and for how the RESP fits next to a TFSA and RRSP, see our saving and investing hub.
Frequently asked questions
How much CESG can I catch up on in one year?
You can get up to $1,000 of Basic CESG in a calendar year if your child has unused grant room from earlier years. That takes a $5,000 contribution, since the grant is 20% of what you put in. Without unused room, the yearly maximum is $500 on a $2,500 contribution.
Is it too late to get the full $7,200 RESP grant?
Not if your child turns 10 or younger this year. Starting in the year a child turns 10, you can still collect the full $7,200 by contributing $5,000 a year for seven years and $1,000 in the year they turn 17. From age 11 on, the most you can collect drops by $1,000 for each later starting year.
Does grant room build up if I never opened an RESP?
Yes. ESDC says unused Basic CESG room accumulates for each child even if they are not a beneficiary of an RESP. For children born in 2007 or later, $500 of room is added every year starting in the year of birth, until the end of the year they turn 17.
Can I get the CESG if my child is 16 or 17?
Only if the RESP met one condition before the end of the year the child turned 15: at least $2,000 contributed and not withdrawn, or at least $100 contributed and not withdrawn in any four earlier years. If you start an RESP at 16 with nothing in place, no CESG is paid.
What happens to the grant if my child does not go to college or university?
The CESG can be shared with a sibling who has grant room available. Otherwise it must be returned to the Government of Canada.
If I put in $20,000 at once, do I get more grant later?
No. The grant is based on what you contribute in each calendar year, capped at 20% of $5,000 when you have unused room. Money above that in one year never attracts grant in a later year. What carries forward is grant room, not contributions.

- Method: A Python model applied the rules year by year (room added each calendar year, grant equal to the lowest of 20% of contributions, $1,000, room and remaining lifetime cap, and the age 16 and 17 test). It reproduces ESDC’s published 2015 to 2020 grant room example exactly. Results for ages 9 to 15 were re-checked with a closed formula: the lesser of $7,200 and $1,000 times the years left through age 17.
