How to Maximize the CESG: Yearly Amount, Catch-Up and the $7,200 Lifetime Limit

The Canada Education Savings Grant (CESG) is the main reason families use an RESP. This page covers how to collect all of it: the yearly contribution that earns the basic grant, how missed years can be recovered, the income-tested Additional CESG, and the provincial grants that sit on top. For the account itself, the complete RESP guide covers the basics, and the RESP hub lists every related guide.

How the CESG is calculated

The grant is tracked per child, not per plan: if a parent and a grandparent both contribute for the same child, their contributions are added together to work out that year’s grant.

Contributing from birth

Contributing $2,500 every year from the year of birth collects the full $500 each year. At that pace the $7,200 lifetime limit takes 14.4 years of grants: 14 full years plus part of the 15th, which is the year the child turns 14. From then on, contributions still grow tax-sheltered but earn no more CESG.

A monthly contribution of about $208 reaches the yearly amount by December 31. Contributions count toward the year in which the plan receives them, so a deposit that lands in January counts toward the new year.

Catching up on missed years

Grant room builds up whether or not the child has an RESP. When a plan is opened late, or contributions stop for a few years, the unused room can be claimed later, but only at a limited pace: a plan can receive at most $1,000 of basic CESG in a year, which takes a $5,000 contribution. That is one current year plus one missed year at a time.

The table shows the most basic CESG a plan can still collect, depending on the year contributions start, if the full catch-up amount goes in every year until the year the child turns 17.

Two conditions sit behind these figures. A child started earlier than age 10 has enough years left to reach the lifetime limit with room to spare. And the grants for the years the child turns 16 and 17 depend on a contribution history built by the end of the year they turned 15; the catch-up amounts above meet it, but smaller late contributions may not. That test and the other cutoffs are covered on the CESG deadline page.

Worked example: a child who turns 10 this year, no RESP yet

• Grant room built so far: $500 for each year from birth through this year (11 years), or $5,500.
• Contributing $5,000 this year brings in $1,000; the unused room keeps growing by $500 a year.
• Doing the same each year through the year the child turns 17 is 8 grant years, enough to reach the $7,200 limit in the final year.

Lump sums

A lump sum doesn’t speed up the grant. A plan that receives $15,000 in one year still gets at most $1,000 of CESG that year; the rest of the deposit earns no grant, then or later. Spreading the same money over three years at $5,000 a year collects the grant three times. The trade-off is that the lump sum starts growing sooner, so families with enough room sometimes do both.

The Additional CESG for lower and middle incomes

Families with adjusted family net income under the thresholds get an extra grant on the first $500 contributed each year:

Income thresholds are indexed annually and match the first two federal tax bracket thresholds. Source: canada.ca/en/services/benefits/education/education-savings/estimating-amounts.html (Table 2), verified September 2, 2026. Lifetime CESG maximum is $7,200 regardless of income level.

The Additional CESG counts toward the same $7,200 lifetime limit. Unlike the basic grant, it can’t be caught up: a year with less than $500 contributed loses some or all of that year’s top-up for good. For qualifying families, $500 a year is therefore the contribution that matters most.

Families in the lower income range may also qualify for the Canada Learning Bond, which needs no contribution at all; the RESP guide’s Canada Learning Bond section explains how to request it.

Provincial RESP grants

Two provinces add their own money to RESPs:

Quebec’s yearly QESI rate and its low-income top-up are set by Revenu Québec; confirm the current amounts on its site. Saskatchewan’s SAGES grant and Alberta’s ACES grant are no longer paid.

Provincial grants follow their own rules when the beneficiary changes or a plan closes, so check with the provider before moving money between plans.

Mistakes that cost grant money

• Leaving the family’s income-tested top-up unused. The Additional CESG disappears each year it isn’t claimed.
• Relying on one big catch-up late. The pace limit means a plan started in the teens can’t recover the full amount.
• Missing the age-15 contribution history. Without it, the plan gets no CESG in the years the child turns 16 and 17.
• Not requesting the Canada Learning Bond or the BCTESG. Both need a request through the provider.
• Two relatives contributing without coordinating. Grant is paid on the child’s combined contributions, so a second plan doesn’t double the grant, and the combined total also counts toward the lifetime limit covered in our RESP overcontribution guide.
