$1.5M Insured Mortgage Cap & 30-Year Amortizations: How the Dec 2024 Rules Help You Buy

The rules that took effect December 15, 2024 do two things, both of which expand a buyer’s purchasing power:

• Insured mortgage cap: $1M → $1.5M. In Canada, when a home is priced below the cap you can take a high-ratio mortgage (less than 20% down, with default insurance from CMHC or a private insurer). Raising the cap to $1.5M brings far more GTA homes into ‘low-down-payment’ territory.
• 30-year amortizations expanded. Insured mortgages were previously capped at 25 years. Now all first-time buyers — regardless of down payment — and anyone buying new construction can choose 30 years.

How the Higher Cap Cuts the Down Payment

Canada’s down-payment rule is tiered: 5% on the first $500,000, 10% on the portion above that.

On a $1.5M home: $500K × 5% + $1M × 10% = $25,000 + $100,000 = $125,000 down.

Under the old rules, $1.5M exceeded the $1M insured cap, forcing an uninsured mortgage requiring 20% — that’s $300,000. The new rules more than halved the threshold. (Source: Department of Finance Canada)

How a 30-Year Amortization Lowers Payments

Stretching amortization from 25 to 30 years lowers the monthly payment, which can help a buyer pass the stress test and afford a higher price. The trade-off: more total interest, slower payoff, and slower equity build-up.

It’s a cash-flow vs. total-cost decision: first-time buyers stretched on monthly payments may benefit; buyers with ample cash flow may not need it.

Two groups: (1) all first-time buyers (any down payment, insured or not) and (2) anyone buying a newly built home (no first-time requirement). If you’re neither a first-time buyer nor buying new, insured mortgages remain capped at 25 years.

Less than 20% down requires mortgage default insurance (CMHC / Sagen / Canada Guaranty). The premium is a percentage of the loan and is usually added to your principal. Factor it into your total budget — don’t let a lower down payment hide it.

Q: What's the minimum down payment on a $1.5M home now?

Per the Department of Finance Canada (2024), since December 15, 2024 the insured cap is $1.5M. Using the tiered rule, a $1.5M home needs $500K × 5% + $1M × 10% = $125,000 down, assuming you qualify for a high-ratio mortgage.

Q: Can everyone use a 30-year amortization?

No. The 30-year option applies to two groups: all first-time buyers (any down payment) and anyone buying newly built housing. If you’re neither, insured mortgages remain capped at 25 years.

Q: When did the insured mortgage cap increase?

It took effect December 15, 2024 — the first change to the insured price cap since 2012 — raising it from $1 million to $1.5 million.

Q: What's the downside of a 30-year amortization?

Lower monthly payments and easier stress-test qualification, but more total interest, a slower payoff, and slower equity growth. You’re trading higher long-term cost for easier short-term cash flow.
