Mortgage Insurance Rule Changes Enable Homeowners to Add Secondary Suites

Jenn Slater • January 2, 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.

Alternative lending refers to any lending practices that fall outside the normal banking channels. Alternative lenders think outside the box and offer solutions to Canadians who wouldn’t otherwise qualify for traditional mortgage financing. In an ideal world, we’d all qualify for the best mortgage terms available. However, this isn’t the case. Securing the most favourable terms depends on your financial situation. Here are a few circumstances where alternative lending might make sense for you. Damaged Credit Bad credit doesn’t disqualify you from mortgage financing. Many alternative lenders look at the strength of your employment, income, and your downpayment or equity to offer you mortgage financing. Credit is important, but it’s not everything, especially if there is a reasonable explanation for the damaged credit. When dealing with alternative lending, the interest rates will be a little higher than traditional mortgage financing. But if the choice is between buying a property or not, or getting a mortgage or not, having options is a good thing. Alternative lenders provide you with mortgage options. That’s what they do best. So, if you have damaged credit, consider using an alternative lender to provide you with a short-term mortgage option. This will give you time to establish better credit and secure a mortgage with more favourable terms. Use an alternative lender to bridge that gap! Self-Employment If you run your own business, you most likely have considerable write-offs that make sense for tax planning reasons but don’t do so much for your verifiable income. Traditional lenders want to see verifiable income; alternative lenders can be considerably more understanding and offer competitive products. As interest rates on alternative lending aren’t that far from traditional lending, alternative lending has become the home for most serious self-employed Canadians. While you might pay a little more in interest, oftentimes, that money is saved through corporate structuring and efficient tax planning. Non-traditional income Welcome to the new frontier of earning an income. If you make money through non-traditional employment like Airbnb, tips, commissions, Uber, or Uber eats, alternative lending is more likely to be flexible to your needs. Most traditional lenders want to see a minimum of two years of established income before considering income on a mortgage application. Not always so with alternative lenders, depending on the strength of your overall application. Expanded Debt-Service Ratios With the government stress test significantly lessening Canadians' ability to borrow, the alternative lender channel allows expanded debt-service ratios. This can help finance the more expensive and suitable property for responsible individuals. Traditional lending restricts your GDS and TDS ratios to 35/42 or 39/44, depending on your credit score. However, alternative lenders, depending on the loan-to-value ratio, can be considerably more flexible. The more money you have as a downpayment, the more you’re able to borrow and expand those debt-service guidelines. It’s not the wild west, but it’s certainly more flexible. Connect anytime Alternative lending can be a great solution if your financial situation isn’t all that straightforward. The goal of alternative lending is to provide you with options. You can only access alternative lending through the mortgage broker channel. Please connect anytime if you’d like to discuss mortgage financing and what alternative lending products might suit your needs; it would be a pleasure to work with you.

As patios wind down and pumpkin spice ramps up, fall is the perfect reset for your home—and your homeowner game plan. These quick wins boost comfort, curb appeal, and efficiency now, and set you up for a low-stress winter (and a strong spring market). 1) Safety & “silent leak” checks (Weekend-ready) Clean gutters & downspouts. Add leaf guards where trees overhang. Roof scan. Look for lifted shingles, cracked flashings, or moss. Seal the shell. Re-caulk window/door trim; replace weatherstripping. Test alarms. New batteries for smoke/CO detectors; add one near bedrooms. Why it matters: Prevent water intrusion and heat loss before storms roll in. 2) Heat smarter, not harder Furnace/boiler tune-up and filter change. Smart thermostat with schedules and geofencing. Draft hunt. Foam gaskets behind outlets, door sweeps on exterior doors. ROI tip: Efficiency upgrades lower monthly bills and can improve lender ratios if you’re eyeing a refinance later. 3) Fall-proof your yard (so spring you says “thanks”) Aerate + overseed + fall fertilize for thicker turf next year. Trim trees/shrubs away from siding and power lines. Mulch perennials and plant spring bulbs now. Shut off/bleed exterior taps and store hoses to avoid burst pipes. 4) Extend outdoor season (cozy edition) Portable fire pit or propane heater + layered blankets. Path/step lighting for darker evenings (solar or low-voltage). Weather-resistant storage for cushions/tools to preserve value. Neighborhood curb appeal: Warm lighting and tidy beds make a big first impression if you list in shoulder season. 5) Water management = winter peace of mind Re-grade low spots and add downspout extensions (2–3+ metres). Check sump pump (and backup). Look for efflorescence or damp corners in the basement. 6) Mini-renos that punch above their weight Entry/mudroom upgrade: hooks, bench, boot trays, closed storage. Laundry room tune-up: counter over machines, sorting bins, task lighting. Kitchen refresh: new hardware, tap, and under-cabinet lighting in one afternoon. Budget guide: Many of these land under a micro-reno budget—perfect for a modest line of credit. 7) Indoor air quality tune-up Deep clean vents and dryers (including the rigid duct). Add door mats (exterior + interior) to catch grit/salt. Houseplants or HEPA purifier for closed-window months. Fast Timeline (pin this to the fridge) Late August–September Gutters/downspouts, roof/caulking, HVAC service, lawn care, plant bulbs, exterior tap shut-off plan, path lighting. October Weatherstripping/sweeps, fire pit setup, organize mudroom/garage, test alarms, sump check, downspout extensions, dryer vent cleaning. Financing smarter: make your mortgage work for your home Annual mortgage check-in. As rates, income, and goals evolve, a quick review can free up cash flow or open options for a small fall project budget. HELOC vs. top-up refinance. For bite-size projects, a HELOC can be flexible. For bigger renos you plan to pay down, a top-up refi might make more sense. Bundle & prioritize. Knock out the high-impact, low-cost items first (air sealing, safety, water management) before the cosmetic upgrades. Not sure which route fits your fall plans? We’ll run the numbers and map the best financing path for your specific budget and goals.
