Mortgage Insurance Rule Changes Enable Homeowners to Add Secondary Suites

Bill Fraser • January 3, 2025

As housing affordability challenges persist across Canada, innovative solutions are reshaping the way homeowners can contribute to housing supply. Starting January 15, 2025, new mortgage insurance rule changes will allow Canadian homeowners to access insured refinancing options to create secondary suites, such as basement apartments or laneway homes.


This move, announced in Budget 2024 and detailed by the Department of Finance Canada, is part of a broader strategy to increase housing density and improve affordability while offering homeowners the chance to generate additional income.


Why These Changes Matter

Historically, converting extra space into rental units has been both costly and mired in municipal red tape. Recent zoning reforms across Canada’s major cities, driven by Housing Accelerator Fund agreements, are reducing these barriers. The creation of secondary suites not only expands housing supply but also provides financial benefits to homeowners, such as offering seniors additional income to support aging in place.


Key Parameters for the New Rules

The new mortgage insurance program is designed to enable homeowners to build legal, self-contained secondary suites that comply with municipal requirements.


Here are the essential details:

Eligibility Requirements

Homeowners must already own the property.

The homeowner or a close relative must occupy one of the existing units.

Additional units must not be used as short-term rentals.


Project Specifications

New units must be fully self-contained with separate entrances (e.g., basement suites, laneway homes).

Up to four total dwelling units are allowed, including existing units.


Financial Parameters

The “as improved” property value must be less than $2 million.

Homeowners can refinance up to 90% of the property’s value, including the enhanced value from secondary suites.

The maximum amortization period is 30 years.

Additional financing must not exceed the project’s costs.


When Do These Rules Take Effect?

Starting January 15, 2025, lenders can submit applications for mortgage insurance under these updated parameters. This applies to all eligible properties across Canada, provided the new units align with municipal zoning requirements.


What This Means for Homeowners

For homeowners with underutilized space, such as basements or detached garages, this new program offers an opportunity to increase property value and create a source of long-term income. By building legal secondary suites, homeowners can contribute to Canada’s rental housing market while gaining financial security.


A Step Toward Housing Solutions

As housing supply remains a pressing issue, these mortgage insurance changes reflect a commitment to practical, homeowner-driven solutions. Whether you’re a senior looking to age in place or a family seeking to maximize your property’s potential, these changes represent an exciting opportunity to invest in your home and your community.

Stay informed and explore your options with your lender to determine if this program is right for you. The path to unlocking your property’s potential begins in 2025.

Wondering If Now’s the Right Time to Buy a Home? Start With These Questions Instead. Whether you're looking to buy your first home, move into something bigger, downsize, or find that perfect place to retire, it’s normal to feel unsure—especially with all the noise in the news about the economy and the housing market. The truth is, even in the most stable times, predicting the “perfect” time to buy a home is incredibly hard. The market will always have its ups and downs, and the headlines will never give you the full story. So instead of trying to time the market, here’s a different approach: Focus on your personal readiness—because that’s what truly matters. Here are some key questions to reflect on that can help bring clarity: Would owning a home right now put me in a stronger financial position in the long run? Can I comfortably afford a mortgage while maintaining the lifestyle I want? Is my job or income stable enough to support a new home? Do I have enough saved for a down payment, closing costs, and a little buffer? How long do I plan to stay in the property? If I had to sell earlier than planned, would I be financially okay? Will buying a home now support my long-term goals? Am I ready because I want to buy, or because I feel pressure to act quickly? Am I hesitating because of market fears, or do I have legitimate concerns? These are personal questions, not market ones—and that’s the point. The economy might change tomorrow, but your answers today can guide you toward a decision that actually fits your life. Here’s How I Can Help Buying a home doesn’t have to be stressful when you have a plan and someone to guide you through it. If you want to explore your options, talk through your goals, or just get a better sense of what’s possible, I’m here to help. The best place to start? A mortgage pre-approval . It’s free, it doesn’t lock you into anything, and it gives you a clear picture of what you can afford—so you can move forward with confidence, whether that means buying now or waiting. You don’t have to figure this out alone. If you’re curious, let’s talk. Together, we can map out a homebuying plan that works for you.

Bank of Canada maintains policy rate at 2¼%. FOR IMMEDIATE RELEASE Media Relations Ottawa, Ontario January 28, 2026 The Bank of Canada today held its target for the overnight rate at 2.25%, with the Bank Rate at 2.5% and the deposit rate at 2.20%. The outlook for the global and Canadian economies is little changed relative to the projection in the October Monetary Policy Report (MPR). However, the outlook is vulnerable to unpredictable US trade policies and geopolitical risks. Economic growth in the United States continues to outpace expectations and is projected to remain solid, driven by AI-related investment and consumer spending. Tariffs are pushing up US inflation, although their effect is expected to fade gradually later this year. In the euro area, growth has been supported by activity in service sectors and will get additional support from fiscal policy. China’s GDP growth is expected to slow gradually, as weakening domestic demand offsets strength in exports. Overall, the Bank expects global growth to average about 3% over the projection horizon. Global financial conditions have remained accommodative overall. Recent weakness in the US dollar has pushed the Canadian dollar above 72 cents, roughly where it had been since the October MPR. Oil prices have been fluctuating in response to geopolitical events and, going forward, are assumed to be slightly below the levels in the October report. US trade restrictions and uncertainty continue to disrupt growth in Canada. After a strong third quarter, GDP growth in the fourth quarter likely stalled. Exports continue to be buffeted by US tariffs, while domestic demand appears to be picking up. Employment has risen in recent months. Still, the unemployment rate remains elevated at 6.8% and relatively few businesses say they plan to hire more workers. Economic growth is projected to be modest in the near term as population growth slows and Canada adjusts to US protectionism. In the projection, consumer spending holds up and business investment strengthens gradually, with fiscal policy providing some support. The Bank projects growth of 1.1% in 2026 and 1.5% in 2027, broadly in line with the October projection. A key source of uncertainty is the upcoming review of the Canada-US-Mexico Agreement. CPI inflation picked up in December to 2.4%, boosted by base-year effects linked to last winter’s GST/HST holiday. Excluding the effect of changes in taxes, inflation has been slowing since September. The Bank’s preferred measures of core inflation have eased from 3% in October to around 2½% in December. Inflation was 2.1% in 2025 and the Bank expects inflation to stay close to the 2% target over the projection period, with trade-related cost pressures offset by excess supply. Monetary policy is focused on keeping inflation close to the 2% target while helping the economy through this period of structural adjustment. Governing Council judges the current policy rate remains appropriate, conditional on the economy evolving broadly in line with the outlook we published today. However, uncertainty is heightened and we are monitoring risks closely. If the outlook changes, we are prepared to respond. The Bank is committed to ensuring that Canadians continue to have confidence in price stability through this period of global upheaval. Information note The next scheduled date for announcing the overnight rate target is March 18, 2026. The Bank’s next MPR will be released on April 29, 2026. Read the January 28th, 2026 Monetary Report
