Five percent is Canada's minimum down payment, and for many GTA buyers it's the realistic starting point — not a fallback. It works for a specific range of purchase prices, comes with predictable insurance costs, and has implications for your monthly payment that are worth understanding before you start making offers. Here's exactly how it works.

Where 5% down actually applies

The 5% minimum applies to the first $500,000 of a purchase price. Once a property is priced above $500,000, a blended minimum kicks in: 5% on the first $500,000 and 10% on the portion above. This means a pure 5% down payment only works as the minimum contribution on properties priced at $499,999 or below.

In practice, this is a meaningful constraint in the GTA. Most detached homes in Toronto proper are well above $1,000,000, where 20% is required and CMHC insurance isn't available at all. Condos and some semi-detached homes in outlying areas do fall in the $500,000–$700,000 range where the blended minimum applies — meaning buyers who planned for "5% down" may find they need closer to 6–8% once the blended calculation is applied.

For a property priced at exactly $499,999, your minimum down payment is $24,999.95 — roughly $25,000. For a $600,000 property, the minimum is $45,000 (5% of $500,000 = $25,000 plus 10% of $100,000 = $10,000, plus the fractional remainder). The difference is material on a savings timeline.

The CMHC premium at 5% down

A 5% down payment triggers the highest CMHC mortgage default insurance premium: 4.00% of the loan amount. On a $480,000 purchase with $24,000 down, your insured loan is $456,000 — and the 4% premium adds $18,240, making your total mortgage $474,240. That premium is typically rolled into the mortgage rather than paid at closing, but it does mean you're borrowing more than the purchase price minus your down payment.

At a 5% mortgage rate over a 25-year amortization, carrying that additional $18,240 in premium costs roughly $30,000 in total interest over the life of the loan. That is the real cost of the 5% entry point — not negligible, but for many buyers it's the price of entering the market earlier rather than spending years saving to 20%.

What your monthly payment looks like

Using a $500,000 purchase price as a benchmark, with 5% down ($25,000), the insured loan becomes $500,200 (after rolling in the 4% premium on $475,000). At a 5-year fixed rate of approximately 4.5% amortized over 25 years, the monthly mortgage payment is roughly $2,730. Add estimated monthly property tax ($400–$500 for a condo or townhouse at this price) and heat ($100–$150) and you're looking at approximately $3,230–$3,380 in monthly housing costs before any condo maintenance fees.

To qualify at the stress test rate (contract rate plus 2%, so approximately 6.5% in this scenario), you need gross monthly household income sufficient to keep that payment within the 39% GDS ceiling. Working backward: $3,300/month in housing costs requires roughly $8,460/month gross ($101,500/year). For couples, that income can be combined — a common scenario is two incomes totalling $110,000–$120,000/year qualifying for a $500,000 purchase with 5% down and no other major debt.

What the 5% scenario restricts

Beyond the price ceiling on pure 5% down, there are other constraints worth knowing:

  • Amortization cap — insured mortgages (any purchase under 20% down) are capped at 25-year amortization in most cases. Uninsured mortgages can extend to 30 years, which reduces monthly payments but increases total interest paid
  • Rental suite income — some buyers plan to purchase a property with a secondary suite and use rental income to offset mortgage costs. CMHC has rules about using rental income to qualify on an insured purchase; confirm with your lender before factoring rental income into your affordability calculation
  • Property type restrictions — CMHC insured mortgages are for owner-occupied primary residences only; investment properties and rentals require at least 20% down regardless of purchase price

When 5% makes sense vs. waiting for more

There is no universally correct answer, but the decision generally comes down to two comparisons: how quickly you can realistically accumulate additional down payment, versus how much home prices in your target area are likely to appreciate during that period.

If you can reach 10% down within 12–18 months of when you could otherwise buy at 5%, the CMHC premium savings (moving from the 4% to the 3.1% tier) and slightly smaller loan may be worth the wait. The premium difference on a $500,000 loan is roughly $4,275 — meaningful, but not always worth a year or more of renting in the GTA market.

If reaching 20% down would take 4–6 additional years, and you're renting at market rate in the GTA during that time, the comparison almost never favours waiting — the combination of rent costs and potential price appreciation generally outweighs the insurance premium savings. This is why the 5% (or blended minimum) entry point exists and is used frequently by first-time buyers who have stable income and income growth ahead of them.

Frequently asked questions

Is the CMHC premium tax-deductible?

No. The CMHC mortgage default insurance premium is not tax-deductible for owner-occupied residential purchases. It is also subject to Ontario's 8% provincial sales tax (PST), which is payable at closing and cannot be rolled into the mortgage — plan for this as a separate closing cost item.

Can I put 5% down on a home over $1,000,000?

No. Homes priced at $1,000,000 or above require a minimum 20% down payment and are not eligible for CMHC-insured mortgages regardless of the buyer's qualifications.

What if I find a property at exactly $500,000?

A $500,000 purchase price requires a minimum $25,000 down payment (5% of the full purchase price), not the blended calculation. The blended minimum (5% on first $500,000, 10% on the remainder) only kicks in for properties above $500,000. At exactly $500,000, the minimum is simply 5%.

Does a 5% down payment affect my interest rate?

Not directly — lenders don't typically price rate differently based solely on down payment amount. However, insured mortgages (under 20% down) have access to slightly different rate pools from some lenders because the mortgage is government-backed. In some market conditions this means insured mortgage rates can actually be marginally lower than uninsured rates, because the lender bears less default risk. In other conditions they are equivalent. Confirm with your lender or mortgage broker.
