Understanding Canada's New Mortgage Rules: Insights from a Broker

As Canada continues to grapple with housing affordability challenges, new federal mortgage rules are being introduced to provide some relief to potential homebuyers. These changes are designed to offer more flexibility and support for Canadians buying in an increasingly expensive real estate market. For many, these new rules may provide the opportunity to step onto the property ladder for the first time, while others could benefit from the ability to tap into the equity in their homes.

In this blog, we’ll break down the key aspects of these new rules, and explore how they can impact prospective buyers. 

Key Changes to Canada’s Mortgage Rules

1. Extension of Amortization Period to 30 Years

One of the most significant changes in Canada’s mortgage regulations is the extension of the amortization period on insured mortgages (less than 20% down). Previously, the maximum allowable amortization period was 25 years, but as of December 15, 2024, that limit has been increased to 30 years for all first-time buyers, on resale or new homes, and for any buyer of a newly built home. The same reforms raised the price cap for insured mortgages from $1 million to $1.5 million, so buyers of homes under $1.5 million can now qualify with less than 20% down.

Why This Matters for First-Time Homebuyers

This rule change is especially beneficial for first-time homebuyers. By extending the amortization period, buyers can spread their mortgage payments over a longer time frame, resulting in lower monthly payments. For those struggling to afford a home in an already inflated market, this could make a substantial difference in terms of affordability.

For example, a homebuyer purchasing a property at $500,000 might have to pay significantly higher monthly mortgage payments if they are locked into a 25-year amortization. With the extended 30-year amortization, those same buyers could see their monthly payments reduced by hundreds of dollars, easing the pressure on their finances and potentially freeing up more room in their budget for other expenses.

Increased Buying Power

In addition to making monthly payments more manageable, the extended amortization could also increase the buying power for first-time buyers. For many, this could mean the difference between being able to purchase a home or continuing to rent. With lower monthly payments, buyers may now be able to afford a more expensive home that would have previously been out of reach.

However, brokers also caution that while this change can help get more buyers into the market, it could also result in them paying more interest over the life of the loan due to the extended repayment period.

2. Secondary Suites Refinancing – Access to Additional Financing

Another major change took effect on January 15, 2025, and involves refinancing for secondary suites. Homeowners can now get an insured refinance to build a secondary suite (an additional dwelling unit, or ADU): up to 90% of the property’s value including the value the suite adds, with up to a 30-year amortization, on properties whose “as improved” value is under $2 million.

The Benefit of Secondary Suites

The ability to tap into home equity for the purpose of adding a secondary suite is a potentially transformative change for homeowners. For those with a large enough property, adding an ADU can generate extra rental income, which could help with mortgage payments or provide financial stability. This is particularly attractive in cities with high demand for rental properties and where rental income can significantly offset housing costs.

Mortgage brokers point out that this measure could also be an avenue for homeowners looking to maximize the value of their property. Whether it’s creating a rental unit for additional income or building a space for a family member, the flexibility to access equity for this purpose is a welcome option for many.

Eligibility and Restrictions

It’s important to note that this refinancing option applies only to homeowners who already own their property. The property can have at most four units including the existing one, and you or a close relative must live in one of them. Outside this program, a regular refinance is still capped at 80% of your home’s value. To qualify, homeowners must meet the specific requirements set out by the federal government, as outlined in a news release issued in October.

While this measure has the potential to help homeowners, brokers advise that individuals carefully consider their financial situation before moving forward. They recommend speaking to a mortgage professional to understand the long-term implications of borrowing against home equity, particularly for those who may already be stretched thin with existing financial obligations.

3. More Opportunities, but More Costs

While these changes open doors to more Canadians who may have previously been shut out of the housing market, they also come with caveats. Specifically, spreading out mortgage payments over a longer period may result in buyers paying significantly more in interest over the life of the loan. This could be a disadvantage for those who have the means to pay off their mortgage sooner but choose the extended amortization for the sake of affordability.

The leading mortgage brokers in the country warn that while these new rules make it easier to qualify for a mortgage, prospective buyers must fully understand the long-term financial commitment. The overall cost of borrowing over 30 years could add up quickly, and the benefits of lower monthly payments should be weighed against the extra interest paid over time.

The Reality of Housing Affordability

Despite the federal government’s efforts to make homeownership more accessible, the latest data still paints a sobering picture for many Canadians. In large cities like Toronto, Vancouver, and Montreal, the income required to purchase a home continues to climb. Even with the new measures in place, buying a typical home in these cities still requires a household income well above the national median.

The introduction of extended amortization periods and refinancing options may help ease the burden for some, but these changes are unlikely to solve the affordability crisis for everyone. Rising home prices, coupled with high demand, continue to place a significant barrier in front of many would-be homebuyers. While these measures will undoubtedly help some buyers, the overall affordability gap remains a challenge.
