The Real Minimum Down Payment for a First-Time Buyer in Canada: Thresholds, Tiers, and Trade-offs
Canada's minimum down payment is tiered by purchase price: 5% on the first $500,000, 10% on the portion between $500,000 and $1,499,999, and 20% on any purchase at or above $1,500,000 — the last threshold raised from $1,000,000 in December 2024. Below the $1.5M ceiling, any down payment under 20% triggers mandatory CMHC (or Sagen/Canada Guaranty) default insurance, with premiums ranging from 2.80% to 4.00% of the insured loan amount depending on LTV. The insured route typically delivers a lower contract rate than an uninsured mortgage, which partially offsets the premium cost — but the math depends on your purchase price, hold period, and rate spread.
Who this is for
Salaried first-time buyers in Canada who have accumulated some savings and need to understand exactly how much down payment is required, how CMHC insurance premiums are calculated, and whether a larger down payment changes their rate or qualification.
- Down payment ($750k purchase, 10% down)
- $75,000 (LTV 90%)
- CMHC premium tier — 90.01–95% LTV (applies when putting the 5–9% minimum down)
- 4.00% of insured loan
- CMHC premium tier — 85.01–90% LTV (applies to this worked example at 90% LTV)
- 3.10% of insured loan ($20,925 on $675k)
- Insured vs. uninsured rate spread (approx. 2026)
- ~25–35 bps lower on insured 5-yr fixed
- Insured mortgage ceiling (post-Dec 2024)
- $1,499,999 purchase price
Framework
The three-tier down payment structure
Tier 1 — Purchases up to $500,000: Minimum 5% down. A $400,000 purchase requires $20,000. This is the entry point for insured high-ratio financing.
Tier 2 — Purchases $500,001 to $1,499,999: Blended minimum. 5% on the first $500,000 ($25,000) plus 10% on the remainder. A $900,000 purchase requires $25,000 + $40,000 = $65,000 (7.22%). A $1,400,000 purchase requires $25,000 + $90,000 = $115,000 (8.21%).
Tier 3 — Purchases at $1,500,000 or above: Minimum 20% down, no default insurance available. The December 2024 reform raised this ceiling from $1,000,000, opening insured financing to a large segment of the Toronto and Vancouver resale market that was previously locked into the conventional 20% threshold. Lenders will not insure properties at or above $1.5M regardless of borrower profile.
CMHC premium tiers and how they are applied
Default insurance premiums are calculated on the total insured loan amount (purchase price minus down payment) and are added to the mortgage balance at funding — they are not paid at closing in cash, though provincial premium tax (PST in Ontario, Quebec, Manitoba, Saskatchewan) is due at closing and cannot be rolled in.
| LTV Range | Premium Rate |
|---|---|
| 90.01% – 95.00% | 4.00% |
| 85.01% – 90.00% | 3.10% |
| 80.01% – 85.00% | 2.80% |
| 65.01% – 80.00% | 2.40% |
Three insurers operate in Canada: CMHC, Sagen (formerly Genworth), and Canada Guaranty. Premium rates are identical across all three; lender access and niche program availability differ. Most prime lenders accept all three.
Insured vs. uninsured: the rate and cost trade-off
The conventional wisdom that 20% down is always better ignores the rate differential. Insured mortgages carry lower lender risk, which translates to lower contract rates — typically 25–35 bps below uninsured equivalents in the 2025–2026 rate environment. On a $700,000 mortgage at a 30 bps spread over 5 years, the rate saving is approximately $10,500 in interest. The CMHC premium on the same mortgage at 90% LTV is $28,000 (4.00% × $700,000). The break-even is roughly 13–15 years at current spreads — meaning buyers who plan to sell or refinance within that window may be net-ahead paying the premium and taking the lower rate. Run the numbers for your specific purchase price and expected hold period before assuming 20% is optimal.
Eligible down payment sources under B-20 and CMHC rules
OSFI Guideline B-20 and CMHC require lenders to verify the source of all down payment funds. Acceptable sources include:
1. Personal savings (90-day seasoning): Funds must be in your account for at least 90 days. Lenders will request 90-day bank statements.
2. Gifted funds from immediate family: A signed gift letter confirming no repayment obligation is required. The gift must come from a direct family member (parent, sibling, grandparent). Gifted funds from non-family sources are not acceptable for insured mortgages.
3. RRSP Home Buyers' Plan (HBP): First-time buyers can withdraw up to $60,000 per person ($120,000 per couple) from RRSPs tax-free under the HBP, as of the 2024 federal budget increase. Funds must have been in the RRSP for at least 90 days.
4. FHSA (First Home Savings Account): Contributions are tax-deductible; qualifying withdrawals are tax-free. Annual contribution room is $8,000, lifetime limit $40,000 per person.
5. Proceeds from sale of another property: Documented via sale agreement and statement of adjustments.
Borrowed down payments are not permitted for insured mortgages. Unsecured lines of credit, credit card advances, or personal loans used as down payment will disqualify the insured application.
Amortization rules tied to down payment size
The December 2024 reforms also extended the maximum insured amortization to 30 years for first-time buyers purchasing new construction, and subsequently broadened to all first-time buyers purchasing any property as of August 2024. This is a material change: a 30-year amortization on a $700,000 insured mortgage at 4.79% reduces the monthly payment by approximately $340 versus a 25-year amortization, improving GDS/TDS ratios and expanding the qualifying purchase price for a given income. Uninsured mortgages (20%+ down) remain capped at 25 years at federally regulated lenders under B-20, though some provincial credit unions and alternative lenders offer 30-year uninsured terms.
Stress test application at each down payment tier
All federally regulated lenders apply the B-20 stress test regardless of down payment size. The qualifying rate is the greater of the contract rate plus 200 bps or 5.25% (the floor as of 2026). At current insured 5-year fixed rates of approximately 4.79%, the stress test rate is 6.79%. At uninsured rates of approximately 5.09%, the stress test rate is 7.09% — a 30 bps difference that meaningfully affects maximum qualifying purchase price. A household with $120,000 gross income qualifies for approximately $30,000–$40,000 more in purchase price under the insured stress test rate than the uninsured rate, all else equal. This is a second, often overlooked reason why a smaller down payment can expand rather than constrain buying power.
Key considerations
- The December 2024 increase in the insured mortgage ceiling to $1,499,999 is the most significant structural change to first-time buyer access in a decade — buyers in the $1,000,000–$1,499,999 range who previously needed 20% down now qualify for insured financing with as little as 8–9% down, depending on purchase price.
- Provincial land transfer taxes and, in Ontario, the Toronto municipal land transfer tax are due at closing and are not financeable. A $750,000 purchase in Toronto triggers approximately $24,950 in combined provincial and municipal LTT — a cash requirement that competes directly with down payment savings and is frequently underestimated.
- The FHSA and RRSP HBP can be stacked: a couple can access up to $80,000 per person ($40,000 FHSA + $60,000 HBP, less any prior HBP withdrawals) for a combined potential of $160,000 in tax-advantaged down payment funds, subject to RRSP contribution room and FHSA account age.
- Condo purchases require lenders to review the status certificate and reserve fund study. A building with a deficient reserve fund or pending special assessment can affect appraised value and, in some cases, cause lenders to decline insured financing on the property regardless of borrower quality.
- Down payment funds must be fully in your account and documented before the lender issues a commitment. Last-minute transfers from a parent's account without a gift letter, or transfers from a HELOC, will trigger underwriting questions and can delay or void approval.
Common mistakes
- Calculating the minimum down payment as a flat 5% of purchase price regardless of price tier — on a $900,000 purchase this underestimates the required down payment by $15,000 and can collapse a deal at condition removal.
- Forgetting that the CMHC premium is added to the mortgage balance, not paid at closing — borrowers who budget for the premium as a closing cost are surprised when their mortgage balance is higher than the purchase price minus down payment.
- Using a personal line of credit to top up the down payment on an insured application — this is a B-20 violation and will result in an immediate decline if discovered during underwriting, which it typically is via credit bureau inquiry.
- Withdrawing RRSP funds under the HBP without confirming the 90-day seasoning rule — funds contributed to an RRSP within 90 days of withdrawal do not qualify under the HBP and will be treated as taxable income.
- Assuming the stress test rate is the same for insured and uninsured mortgages — the 25–35 bps rate differential between insured and uninsured contracts flows directly into the stress test qualifying rate, affecting maximum purchase price by $30,000–$50,000 at typical income levels.
- Ignoring closing costs when sizing the down payment — legal fees, title insurance, home inspection, and land transfer tax typically add 1.5–2.5% of purchase price in cash requirements on top of the down payment, and none of these are financeable.
Action steps
- 01Calculate your exact minimum down payment using the tiered formula: 5% × min(purchase price, $500,000) + 10% × max(0, purchase price − $500,000), capped at purchases below $1,500,000. Confirm the number before setting a purchase price target.
- 02Open or maximize an FHSA immediately if you have not already — the $8,000 annual contribution room does not carry forward indefinitely, and the account must be open for at least one calendar year before qualifying withdrawals can be made.
- 03Request 90-day bank statements from every account contributing to your down payment and ensure all large deposits are explainable. Unexplained deposits of more than 25% of the account balance will require a paper trail.
- 04Run a side-by-side comparison of the insured (minimum down) versus 20% down scenario using your specific purchase price, expected hold period, and current rate spread — the insured route is frequently cheaper on a net-present-value basis for holds under 10–12 years.
- 05Confirm your closing cost reserve separately from your down payment. Budget a minimum of 1.5% of purchase price for closing costs in addition to the down payment, and 2.5% if purchasing in Toronto or Montreal where municipal LTT applies.
- 06Engage a broker with access to all three default insurers (CMHC, Sagen, Canada Guaranty) — niche programs such as CMHC's Eco Plus rebate or Sagen's New to Canada program may apply to your situation and are not available through single-lender channels.
