RESP: The Most Underused Government Benefit in Canada
The RESP combined with the Canada Education Savings Grant is one of the best guaranteed returns available to Canadian families — yet fewer than 40% of eligible children have an RESP. The government contributes 20% on your first $2,500 annually. That's a 20% instant return before your investments earn a single dollar.
How the CESG works
The Canada Education Savings Grant (CESG) matches 20% of RESP contributions on the first $2,500 per year per child, to a lifetime maximum of $7,200. Low-income families receive additional CESG of 10–20%. To capture the full $7,200, contribute $2,500/year for 15 years (ages 0–14). Contribution room is $50,000 per child lifetime.
The optimal contribution strategy
The mathematically optimal strategy is to contribute exactly $2,500/year to maximize CESG. If you have unused room, you can catch up — but CESG is only paid on $2,500/year regardless of how much you deposit. Lump-sum catch-up contributions grow without grants above the $2,500 threshold.
| Annual Contribution | CESG Received | CESG Efficiency | Recommendation |
|---|---|---|---|
| $1,000 | $200/yr ($3,000 lifetime) | 20% | Good — contribute more if possible |
| $2,500 | $500/yr ($7,200 lifetime) | 20% | Optimal — maximizes all grants |
| $5,000 | $500/yr ($7,200 lifetime) | 10% | OK — extra $2,500 grows without grant |
| $7,000 | $500/yr ($7,200 lifetime) | 7% | Fine if nearing end of grant years |
What if my child doesn't go to university?
RESP funds can be used for any eligible post-secondary program — trade schools, colleges, apprenticeships. If your child doesn't pursue any post-secondary education, grants (CESG) must be returned to the government. Your contributions come back tax-free. Investment gains can be withdrawn (AIP) with a 20% penalty tax on top of your marginal rate, or transferred to your RRSP if you have room.
