If you’ve been waiting for the right conditions to buy a home in Calgary, there’s a good chance the rules changed in your favour — and nobody told you.

In December 2024, the federal government made two significant updates to Canada’s mortgage rules. Together, these changes expanded access to homeownership for first-time buyers and new build purchasers across the country, including right here in Calgary. If you’re working with a mortgage broker or doing your own research, understanding how these rules work could change what you qualify for and how much you need at the table.

Here’s what you need to know about the 30-year mortgage amortization and the new insured mortgage cap — including the honest trade-offs.

What Changed in December 2024?

Two specific changes took effect on December 15, 2024:

1. The 30-year mortgage amortization became available to more buyers.

Before this change, if you were putting down less than 20% on a home purchase — known as a high-ratio or insured mortgage — you were limited to a maximum 25-year amortization. That had been the rule since 2012.

The 30-year mortgage amortization is now accessible in two situations:

  • You’re a first-time homebuyer. This applies whether you’re buying a resale home or a brand-new build. You don’t have to be purchasing new construction to access the longer amortization.
  • You’re purchasing a newly built home. This applies to *any* buyer — not just first-time buyers. If you’re buying a new build with less than 20% down, you qualify for 30 years, regardless of how many homes you’ve owned before.

2. The insured mortgage price cap increased from $1 million to $1.5 million.

Mortgage default insurance — offered through CMHC, Sagen, or Canada Guaranty — allows buyers to purchase a home with less than 20% down. Until December 2024, this was only available on homes priced below $1 million. Above that threshold, a full 20% down payment was required.

That cap has now been raised to $1.5 million, meaning buyers can access insured financing on homes up to that price point, with a minimum down payment of 5% on the first $500,000 and 10% on the portion between $500,000 and $1.5 million.

What Does This Mean for Calgary Homebuyers?

Calgary’s housing market has shifted considerably. Apartment condos are sitting at around $300,000, row homes benchmark near $424,000, and detached homes average around $741,000 across the city — with significant variation by neighbourhood and community.

For most buyers in Calgary, especially those shopping in the condo, row home, and entry-level detached segments, the 30-year mortgage amortization rule is directly relevant.

The payment difference is meaningful.

On a $600,000 home with a 5% down payment, the difference between a 25-year and 30-year amortization works out to roughly $200 to $250 less per month. For a buyer managing other financial obligations — student debt, childcare, a vehicle payment — that reduction in monthly housing costs can be the difference between qualifying and not.

The insured cap change opens doors for move-up buyers.

Calgary’s detached market in established neighbourhoods can push well past $1 million. The old cap at $1 million meant buyers needed a full 20% down on anything above that price. Now, a buyer purchasing a $1.3 million detached home can qualify with as little as $105,000 down rather than $260,000. That’s a significant change in the cash required to close.

The Honest Trade-Off

The 30-year mortgage amortization comes with a cost that’s important to understand before you choose it. Spreading your mortgage over 30 years instead of 25 reduces your monthly payment — but it also means you’re paying interest for five additional years.

On a $500,000 insured mortgage at roughly 4% interest, the difference in total interest paid over the full amortization is approximately $60,000 to $70,000. That’s real money, and a good mortgage broker will walk you through the full picture so you can make a decision that fits your situation — not just your short-term cash flow.

For some buyers, the lower monthly payment is the only realistic path into homeownership right now, and that’s a completely legitimate choice. For others, the added interest cost is a reason to stick with 25 years if they can manage it comfortably. The right answer depends on your income, your other debts, your savings, and your long-term goals.

Who Qualifies?

To access the 30-year mortgage amortization under Canada’s current rules, you need to meet at least one of the following criteria:

  • You are a first-time homebuyer purchasing any type of property (resale or new build) with less than 20% down
  • You are purchasing a newly constructed home — any property type — with less than 20% down

To access the expanded insured mortgage cap of $1.5 million, the home you’re purchasing must be priced below $1.5 million, and your down payment must follow the tiered structure: 5% on the first $500,000 and 10% on the portion above $500,000 up to $1.5 million.

These rules apply to insured mortgages through federally regulated lenders. A mortgage broker can help you confirm your eligibility based on your specific situation.

Is This the Right Move for You?

If you’ve been sitting on the sidelines because of monthly payment concerns or down payment size, it’s worth having a fresh conversation. The rules that applied a year or two ago may not be the rules you’re working under today.

A good starting point is understanding exactly what you qualify for under current guidelines — and then deciding, with full information, whether the 30-year mortgage amortization makes sense for your household.
