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

Carmelo Mamertino • 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.

Worried About Your Mortgage Renewal? You’re Not Alone If your mortgage renewal is coming up soon, you're likely feeling a bit of financial pressure—and you’re not the only one. A recent survey shows that over half of Canadian homeowners believe their upcoming mortgage renewal could impact their current living situation. With interest rates still higher than what many borrowers locked in before 2022, 45% of those renewing in the next 12 months expect their monthly payments to increase. Even though the Bank of Canada has held its key overnight rate steady at 2.75%, borrowing costs remain elevated compared to the low-rate years we saw earlier in the decade. And that’s changing how Canadians think about their finances. Changing Plans and Tightening Budgets Among those worried about their renewal, 73% say they’re already cutting back on discretionary spending—things like eating out, entertainment, or travel—to brace for higher mortgage payments. For many, it goes deeper than just trimming the budget. Nearly one in four surveyed homeowners said they’re rethinking their entire financial strategy. Some are pressing pause on home renovations (43%), while others are considering downsizing or relocating to a more affordable area (29%). A smaller group (15%) is even open to major lifestyle changes, like moving in with roommates or relocating to a new neighbourhood altogether. Fixed-Rate Mortgages on the Rise In this climate, most homeowners looking to renew are leaning toward fixed-rate mortgages, with 75% preferring the stability of predictable payments. For those facing uncertainty, locking in a rate for the next few years can offer peace of mind—even if it means paying a little more in the short term. First-Time Buyers Are Feeling It Too It’s not just current homeowners feeling the pinch. A separate survey found that more than half of Canadians planning to buy a home are cutting back on non-essential spending to save for their down payment or other buying costs. About 31% are even considering tapping into savings or investment accounts like TFSAs, RRSPs, or first-time home savings accounts to make their purchase possible. What This Means for You Whether you’re preparing to renew or purchase for the first time, this environment calls for smart, strategic planning. You’re not alone in feeling uncertain—but with the right guidance, you can navigate these changes confidently. Have questions about your upcoming renewal or wondering what type of mortgage is right for today’s market? Let’s connect. We're here to help you make informed, confident decisions about your home financing.

In recent years, housing affordability has become a significant concern for many Canadians, particularly for first-time homebuyers facing soaring prices and strict mortgage qualification criteria. To address these challenges, the Canadian government has introduced several housing affordability measures. In this blog post, we'll examine these measures and their potential implications for homebuyers. Increased Home Buyer's Plan (HBP) Withdrawal Limit Effective April 16, the Home Buyer's Plan (HBP) withdrawal limit will be raised from $35,000 to $60,000. The HBP allows first-time homebuyers to withdraw funds from their Registered Retirement Savings Plan (RRSP) to use towards a down payment on a home. By increasing the withdrawal limit, the government aims to provide young Canadians with more flexibility in saving for their down payments, recognizing the growing challenges of entering the housing market. Extended Repayment Period for HBP Withdrawals In addition to increasing the withdrawal limit, the government has extended the repayment period for HBP withdrawals. Individuals who made withdrawals between January 1, 2022, and December 31, 2025, will now have five years instead of two to begin repayment. This extension provides borrowers with more time to manage their finances and repay the withdrawn amounts, alleviating some of the immediate financial pressures associated with using RRSP funds for a down payment. 30-Year Mortgage Amortizations for Newly Built Homes Starting August 1, 2024, first-time homebuyers purchasing newly built homes will be eligible for 30-year mortgage amortizations. This change extends the maximum mortgage repayment period from 25 years to 30 years, resulting in lower monthly mortgage payments. By offering longer amortization periods, the government aims to increase affordability and assist homebuyers in managing their housing expenses more effectively. Changes to the Canadian Mortgage Charter The government has also introduced changes to the Canadian Mortgage Charter to provide relief to homeowners facing financial challenges. These changes include early mortgage renewal notifications and permanent amortization relief for eligible homeowners. By implementing these measures, the government seeks to support homeowners in maintaining affordable mortgage payments and mitigating the risk of default during times of financial hardship. The recent housing affordability measures announced by the Canadian government are aimed at addressing the challenges faced by homebuyers in today's market. These measures include increasing withdrawal limits, extending repayment periods, and offering longer mortgage amortizations. The goal is to make homeownership more accessible and affordable for Canadians across the country. As these measures come into effect, it's crucial for homebuyers to stay informed about the changes and their implications. Consulting with a mortgage professional can help individuals explore their options and make informed decisions about their housing finances.
