Reaching a minimum down payment faster comes down to two levers: the price-tiered CMHC minimum itself, and the two registered accounts built to fund it. The First Home Savings Account gives C$8,000 of contribution room a year (C$40,000 lifetime, per Finance Canada's design release) with a tax deduction going in and a tax-free withdrawal coming out. The RRSP Home Buyers' Plan lets you withdraw up to C$60,000 from an existing RRSP, interest-free, repayable over 15 years. Used together for the same home, CRA confirms both withdrawals can apply to one purchase, and the minimum down payment itself scales with price, not a flat percentage.
The minimum isn't 5% — it's tiered by price
CMHC's general requirements page sets the minimum down payment as 5% on the first C$500,000 of the purchase price, then 10% on the portion between C$500,000 and the insured price ceiling. Only homes priced under C$1,500,000 qualify for insured financing at all; above that, insured financing is unavailable and the lender sets its own conventional down-payment minimum.
| Purchase price | Minimum down payment | Calculation |
|---|---|---|
| C$400,000 | C$20,000 (5%) | 5% × C$400,000 |
| C$600,000 | C$35,000 | 5% × C$500,000 + 10% × C$100,000 |
| C$900,000 | C$65,000 | 5% × C$500,000 + 10% × C$400,000 |
| C$1,200,000 | C$95,000 | 5% × C$500,000 + 10% × C$700,000 |
Tiered rule per CMHC, retrieved 2026-09-21. Above C$1,500,000, insured financing is unavailable and a lender-set conventional minimum applies instead.
The tier break matters for savings planning: crossing C$500,000 in purchase price doesn't raise your whole down payment to 10% — it only raises the rate on the amount above C$500,000. A buyer targeting a C$550,000 home needs C$30,000, not C$55,000.
FHSA: C$8,000 a year, C$40,000 lifetime, with a one-year carryforward cap
The FHSA's participation room is C$8,000 in the first year an individual opens the account, per CRA's FHSA overview. Finance Canada's design release sets the lifetime contribution ceiling at C$40,000 and explains the carryforward: unused annual room carries into the next year, but is capped at a maximum of C$8,000 of prior unused room added to the current year's C$8,000. A saver who contributes C$5,000 in year one has C$3,000 of unused room; in year two, participation room is C$8,000 + C$3,000 = C$11,000 — not C$8,000 plus every unused dollar going back.
The account's usable window is also capped. CRA's FHSA definitions page states the participation period ends on December 31 of the year the EARLIEST of three events occurs: the 15th anniversary of opening the individual's first FHSA, the individual turning 71, or the year following their first qualifying withdrawal from any FHSA. Once any one of those trips, further contributions to the account stop.
RRSP Home Buyers' Plan: C$60,000 per person, no tax deduction lost, but repayable
Unlike the FHSA, the HBP doesn't create new contribution room — it lets you withdraw from RRSP savings you (or a spouse's RRSP contributions on your behalf) already made. CRA's Home Buyers' Plan page states the current withdrawal limit is C$60,000 per eligible individual, tax-free at the time of withdrawal, repayable over a 15-year period. For a first HBP withdrawal made between January 1, 2022 and December 31, 2028, the start of that 15-year repayment period is deferred to the fifth year following the withdrawal year — CRA's own example: a withdrawal in 2026 has its first repayment year in 2031, not 2028.
Two eligible co-buyers can each withdraw up to C$60,000 from their own RRSPs, for a combined C$120,000 toward the same home purchase — double the FHSA's per-person lifetime cap, available immediately if the RRSP room already exists, at the cost of a mandatory repayment schedule the FHSA doesn't carry.
FHSA and HBP can be used on the same home purchase
CRA is explicit that these two accounts are not either/or: CRA's Home Buyers' Plan page states a buyer can withdraw under the RRSP HBP AND make a qualifying FHSA withdrawal for the same qualifying home, as long as each withdrawal separately meets its own conditions at the time it's made. Stacked for a couple, that's up to C$80,000 from FHSAs (C$40,000 lifetime each) plus up to C$120,000 from the HBP (C$60,000 each) — up to C$200,000 in registered-account funds toward one purchase, all without capital-gains tax on the growth inside either account. Run your own numbers, including how a smaller down payment changes your CMHC premium, with the CMHC insurance calculator and the FHSA calculator.
What a smaller down payment costs in CMHC premium
Saving toward 20% isn't only about avoiding a monthly obligation — it avoids the CMHC premium outright. Per CMHC's own premium table, the premium is charged as a percentage of the total loan amount, scaled to how thin the down payment is: 4.00% at 5% down, 3.10% at 10% down, and 2.80% at 15% down. On a C$600,000 home financed at 5% down (a C$570,000 loan), a 4.00% premium adds C$22,800 to the mortgage balance — money that then accrues interest for the life of the loan. Reaching just the 10% tier instead (C$540,000 loan at 3.10%) drops the premium to C$16,740, a C$6,060 difference before any interest on the difference is counted.
What counts as a "qualifying" FHSA withdrawal
A tax-free FHSA withdrawal isn't automatic just because the money is in the account. CRA's FHSA definitions page lists the conditions for a qualifying withdrawal: filing Form RC725, meeting the FHSA definition of a first-time home buyer, having a written agreement to buy or build the home in place before the withdrawal (with completion due before October 1 of the following year), not having acquired the home more than 30 days before the withdrawal, staying a Canadian resident from the withdrawal until the acquisition, and intending to occupy the home as a principal residence within one year of buying or building it. Miss one of these and the withdrawal is taxable — plan the withdrawal request around the purchase agreement, not the other way around.
Your income sets a ceiling that a bigger down payment can't fix
Saving a larger down payment lowers the mortgage you need, but it doesn't raise the maximum a lender will approve. CMHC's own underwriting rule caps Gross Debt Service (GDS) at 39% and Total Debt Service (TDS) at 44% of gross household income. GDS covers mortgage principal and interest, property tax, heat, and (for condos) 50% of monthly fees; TDS adds every other debt payment — car loans, credit cards, lines of credit. Whichever ratio is tighter for a given household sets the real ceiling, independent of how much cash is sitting in an FHSA or RRSP.
The mortgage that ceiling actually supports is then tested against the minimum qualifying rate (the stress test): the greater of the mortgage's contract rate plus 2%, or 5.25%, per OSFI. A lower contract rate doesn't necessarily buy a bigger mortgage once that floor kicks in — it only helps once the contract-rate-plus-2% figure exceeds 5.25%.
| Gross annual income | GDS ceiling (39%) | TDS ceiling (44%) |
|---|---|---|
| C$80,000 | C$2,600.00/mo | C$2,933.33/mo |
| C$110,000 | C$3,575.00/mo | C$4,033.33/mo |
| C$140,000 | C$4,550.00/mo | C$5,133.33/mo |
Ceilings are gross income × ratio ÷ 12; CMHC ratios retrieved 2026-09-21.
Methodology
Down payment tiers are read from CMHC's general requirements page; the CMHC premium worked example is arithmetic on the loan amount using the published rate tiers from CMHC's mortgage loan insurance cost page. FHSA figures come from CRA's FHSA overview, Finance Canada's FHSA design release, and CRA's FHSA definitions page. HBP figures and the combined-use rule come from CRA's Home Buyers' Plan page. No figure is estimated or drawn from a non-government source.
