New 2025 Program Allows Homeowners to Refinance Up to 90% for Secondary Suites: What You Need to Know

Glenn Issler • October 18, 2024

On October 8, 2024, the government announced a new program that will take effect on January 15, 2025, allowing homeowners to refinance up to 90% of their home’s value to create secondary suites. This is a significant increase from the current refinancing limit of 80%. The program aims to provide homeowners with more flexibility to unlock their home equity and add additional legal units like basement suites or laneway homes, provided they meet municipal zoning requirements and are not used for short-term rentals.


The program comes with specific guidelines, outlined by CMHC (Canada Mortgage and Housing Corporation), that include:

  • Eligibility: Homeowners must already own their property, live in one of the existing units, and plan to add additional fully self-contained suites.
  • Refinancing Details: Homeowners can refinance up to 90% of the property's value, including the value added by the new units. The maximum property value, once the new units are built, must not exceed $2 million.
  • Loan Parameters: The loan-to-value limit will be 90%, and the maximum amortization period is 30 years. Any additional financing must not exceed project costs.


To give an example, under this new program, if a home is valued at $800,000, homeowners could now refinance up to $720,000 for building a secondary suite—$80,000 more than the previous limit of $640,000.


This program could be particularly beneficial for homeowners who have recently purchased their property and built up a moderate amount of equity, offering them an opportunity to create an income-generating suite or expand their home without needing to sell. As housing affordability continues to be a pressing issue in many parts of Canada, adding secondary suites could also contribute to easing the rental supply shortage.


While this program represents a significant step forward in unlocking home equity for homeowners, we are still awaiting specific guidelines from lenders. These rules will clarify how lenders will approach refinancing applications under this program. Stay tuned for further updates as more information becomes available from financial institutions.


This program is expected to spark significant interest, particularly from younger homeowners or those with growing families, as it offers a pathway to enhance both living space and long-term financial stability. Homeowners looking to leverage this new opportunity should consult with mortgage experts to fully understand the potential benefits and ensure they are making informed decisions.

If you’ve been thinking about buying a second property and you’re looking to put some of the pieces together, you’ve come to the right place! Whether you’re looking to buy a vacation property, start a rental portfolio, or help accommodate a family member, there are many reasons to buy a second property (while keeping your existing property), which might make sense for you! Now, while there are many great reasons to buy a second property, there is also a lot to know as you walk through the process. The key here is to have absolute clarity around your why. Ask yourself, why do you want to buy a second property? This isn’t a decision to be taken lightly or one that should be made too quickly. Buying a second property should be a strategic decision that allows you to accomplish your goals, and it should include an assessment of your overall financial health. So with clear goals in mind, the best place to start the process is to have a conversation with an independent mortgage professional. This will allow you to assess your financial situation, outline the costs, and put together a plan to make it happen. While purchasing a second property is similar to buying a primary residence, there are some key differences. Just because you’ve qualified in the past for your existing mortgage doesn’t mean you’ll qualify to purchase a second property. One key difference is the amount of downpayment you might be required to come up with. A property that is owner-occupied or occupied by a family member on a rent-free basis will require less of a downpayment than if the second property will be used to generate an income. So, depending on the property's intended use, you might have to come up with as much as 25%-35% down. This is where strategic planning comes in. Consider unlocking the equity in your existing home to finance the downpayment to purchase your second home. Here are a few ways you can go about doing that: Securing a new mortgage if you own your property clear title Refinancing your existing mortgage to access additional funds Securing a home equity line of credit (HELOC) Getting a second mortgage behind your existing first mortgage Securing a reverse mortgage The conversation about buying a second property should include assessing your overall financial health, leveraging your existing assets to lower your overall cost of borrowing, and figuring out the best way to accomplish your goals. And as it's impossible to outline every scenario in a simple blog post, if you’d like to discuss your goals and put a plan together to finance a second property, connect anytime. It would be a pleasure to work with you.

The idea of owning a vacation home—your own cozy escape from everyday life—is a dream many Canadians share. Whether it’s a lakeside cabin, a ski chalet, or a beachside bungalow, a second property can add lifestyle value, rental income, and long-term wealth. But before you jump into vacation home ownership, it’s important to think through the details—both financial and practical. Start With Your 5- and 10-Year Plan Before you get swept away by the perfect view or your dream destination, take a step back and ask yourself: Will you use it enough to justify the cost? Are there other financial goals that take priority right now? What’s the opportunity cost of tying up your money in a second home? Owning a vacation home can be incredibly rewarding, but it should fit comfortably within your long-term financial goals—not compete with them. Financing a Vacation Property: What to Consider If you don’t plan to pay cash, then financing your vacation home will be your next major step. Mortgage rules for second properties are more complex than those for your primary residence, so here’s what to think about: 1. Do You Have Enough for a Down Payment? Depending on the type of property and how you plan to use it, down payment requirements typically range from 5% to 20%+ . Factors like whether the property is winterized, the purchase price, and its location all come into play. 2. Can You Afford the Additional Debt? Lenders will calculate your Gross Debt Service (GDS) and Total Debt Service (TDS) ratios to assess whether you can take on a second mortgage. GDS: Should not exceed 39% of your income TDS: Should not exceed 44% If you’re not sure how to calculate these, that’s where I can help! 3. Is the Property Mortgage-Eligible? Remote or non-winterized properties, or those located outside of Canada, may not qualify for traditional mortgage financing. In these cases, we may need to look at creative lending solutions . 4. Owner-Occupied or Investment Property? Whether you’ll live in the home occasionally, rent it out, or use it strictly as an investment affects what type of financing you’ll need and what your tax implications might be. Location, Location… Logistics Choosing the right vacation property is more than just finding a beautiful setting. Consider: Current and future development in the area Available municipal services (sewer, water, road maintenance) Transportation access – how easy is it to get to your vacation home in all seasons? Resale value and long-term potential Seasonal access or weather challenges What Happens When You’re Not There? Unless you plan to live there full-time, you'll need to consider: Will you rent it out for extra income? Will you hire a property manager or rely on family/friends? What’s required to maintain valid home insurance while it’s vacant? Planning ahead will protect your investment and give you peace of mind while you’re away. Not Sure Where to Start? I’ve Got You Covered. Buying a vacation home is exciting—but it can also be complicated.
