Rule Change to Enable Canadian Homeowners to Build Secondary Suites with Mortgage Refinancing

Zach Silverman | January 3, 2025

Housing affordability remains a major challenge across Canada, but a new opportunity is emerging for homeowners. Starting January 15, 2025, updated mortgage insurance rules will allow Canadians to access insured refinancing to build secondary suites—such as basement apartments or laneway homes.


This initiative, introduced in Budget 2024 and detailed by the Department of Finance Canada, aims to increase housing supply, generate rental income for homeowners, and enhance property value.


Why This Matters for Homeowners


Traditionally, converting unused space into rental units has been expensive and complicated by municipal zoning laws. However, recent zoning reforms in Canada’s largest cities are making it easier to create legal secondary suites.


For homeowners, this means:


✔️ Additional income to help with mortgage payments

✔️ Increased property value with legal rental units

✔️ Support for aging in place by creating affordable housing for family members



Key Details of the New Mortgage Rules


Who’s Eligible?

  • Homeowners who already own the property
  • The homeowner or a close relative must live in one of the existing units
  • Additional units cannot be used as short-term rentals

What Types of Units Qualify?

  • Fully self-contained suites with separate entrances
  • Basement apartments, laneway homes, or garden suites
  • Up to four total dwelling units (including existing ones)


Financial Guidelines

  • Property value must be under $2 million (after improvements)
  • Refinancing up to 90% of the home’s value, including added value from new units
  • Maximum 30-year amortization
  • Loan amount cannot exceed the project’s total costs



When Do These Changes Take Effect?


Starting January 15, 2025, lenders can submit applications for mortgage insurance under these new guidelines. Eligible properties across Canada must meet local zoning regulations for secondary suites.

What You Need to Know About Mortgages and Parental Leave

By Zach Silverman • July 22, 2026
If the title of this article caught your attention, chances are your family is growing. Congratulations. If you’re thinking now is the right time to move into a home that better fits your growing family—but you’re unsure how parental leave affects your ability to qualify for a mortgage—you’re in the right place. Here’s the good news. Qualifying for a mortgage while on parental leave is possible when it’s done correctly. When you work with an independent mortgage professional, lenders can often qualify you based on your return-to-work income , as long as you can provide documentation confirming you have guaranteed employment waiting for you. A word of caution If you walk into a bank branch and disclose that you’re currently on parental leave, there’s a chance the bank will only allow you to qualify using your parental leave income. That can significantly reduce your borrowing power. Parental leave income is typically limited to 55% of your previous earnings, up to a weekly maximum. Qualifying on that amount alone can restrict your options and impact the type of home you can purchase. Why lender choice matters One of the biggest advantages of working with an independent mortgage professional is choice . You’re not limited to one lender’s rules or products. Some lenders will allow you to qualify using 100% of your confirmed return-to-work income , which can make a meaningful difference in your approval amount and overall options. What you’ll need to qualify Most lenders will require an employment letter that includes: Employer name (preferably on company letterhead) Your job title Original start date (to confirm probation has been completed) Confirmed return-to-work date Guaranteed salary upon return Lenders want reassurance that your income will resume once parental leave ends. You may also be asked to provide income history from the past couple of years, which is standard for most mortgage applications. One important note Whether or not you actually return to work after parental leave is entirely your decision. From a mortgage perspective, qualification is based on having a confirmed position available to you at the time of approval. If you have questions about qualifying for a mortgage while on parental leave—or anything mortgage-related—please connect anytime. I’d be happy to walk you through your options and help you plan with confidence.

Need Funds Between Buying and Selling? Here’s How Deposit Loans & Bridge Financing Help

By Zach Silverman • July 8, 2026
You’ve outgrown your current home. It no longer fits your life, so moving makes sense. And you’re not interested in juggling two properties. Selling first and buying something new feels like the right move. Ideally, you want possession of the new home before leaving the old one. That overlap makes moving easier, reduces stress, and gives you time to paint, renovate, or settle in before the boxes arrive. But there’s a common challenge. What if the down payment for your next home is tied up in the equity of the one you’re selling? That’s where bridge financing comes in. How bridge financing works Bridge financing temporarily unlocks equity from your current home once it has a firm sale . It bridges the gap between selling your existing property and purchasing your next one, allowing you to use that equity toward your down payment. What about competitive markets? In a hot market, a strong offer often means a larger deposit . If you don’t have that cash sitting in your account, but you do have equity, a deposit loan can help you compete with confidence. The non-negotiable requirement To qualify for bridge financing or a deposit loan, your current home must have a firm, unconditional sale . No firm sale = no bridge or deposit loan. Lenders need certainty to calculate available equity and manage risk. Bottom line A firm sale is the key that unlocks bridge financing and deposit loans. If you’re planning a move and want to understand how these options could work for you, let’s talk. I’m always happy to walk you through your options and help you plan your next step with confidence.
