New Mortgage Rules and CMHC Updates: A Guide for First-Time Buyers

Lisa Manwaring • September 17, 2024

In Budget 2024, the Canadian government introduced significant changes to help first-time homebuyers by extending mortgage amortization periods up to 30 years for those purchasing newly built homes. Effective August 1, 2024, this change will help ease monthly mortgage payments, making homeownership more accessible.


Key Eligibility Criteria for First-Time Buyers:

  • First-Time Buyer Status: At least one borrower must qualify as a first-time homebuyer, meaning they have either never owned a home, haven't lived in a home they owned in the past four years, or recently went through a marriage breakdown.
  • Newly Built Homes: The property must be a newly constructed home that has never been occupied.


These extended mortgages will only apply to high-ratio mortgages (loans covering more than 80% of the home’s purchase price) and are limited to owner-occupied properties. All other mortgage insurance eligibility criteria remain unchanged.


CMHC’s New Amortization Rules for Market MLI and MLI Select Programs

The Canada Mortgage and Housing Corporation (CMHC) has also introduced changes. As of June 19, 2024, the maximum amortization period for new construction market projects will increase from 40 years to 50 years. Additionally, the maximum period for re-amortization (for default management) will extend to 55 years for loans under the MLI Select Program.


These changes aim to encourage the construction of more rental housing units while managing housing affordability. CMHC’s modifications also include updates to energy efficiency criteria, lowering the maximum points from 100 to 50 based on energy efficiency, which means developers may need to shift focus toward affordable units to receive maximum benefits.


Changes to "Use of Funds" and Refinancing

CMHC has lifted restrictions on how refinanced funds can be used, reverting to pre-2020 rules. This allows non-approved lenders to offer bridge loans, creating more flexibility in financing options.


Environmental Site Contamination Policies

In response to industry practices, CMHC is reviewing its environmental site contamination policies. For now, projects with known site contamination will be accepted under conditional approval, pending a contamination-free site confirmation.


Why These Changes Matter

For first-time homebuyers, the ability to spread mortgage payments over 30 years is a welcome relief in today’s housing market, particularly for newly built homes. These changes are designed to improve housing affordability and supply, especially for younger Canadians looking to purchase their first home.


Meanwhile, CMHC’s new rules around extended amortizations and energy efficiency adjustments will have a significant impact on developers, especially those focused on building rental properties or using energy-efficient technologies in their projects.

If you're considering buying a home or developing a property, these changes could impact your strategy. To fully understand how these updates may apply to your situation, it's important to consult with a mortgage expert who can offer personalized advice.

Why a Mortgage Pre-Approval Protects Both Your Head and Your Heart

By Lisa Manwaring • June 3, 2026
Why a Mortgage Pre-Approval Protects Both Your Head and Your Heart There’s no denying it—buying a home is an emotional journey. In a competitive market, it can feel like you need to stretch beyond your comfort zone or bid above asking just to have a chance. That pressure can make it hard to separate what you want from what you can realistically afford. One of the biggest pitfalls buyers face is falling in love with a home that’s outside their price range. Once that happens, every other property seems like a compromise—even the ones that might have been a perfect fit otherwise. The best way to avoid this heartache? Get pre-approved before you start shopping. What a Pre-Approval Does for You A mortgage pre-approval gives you more than just a number—it provides clarity, confidence, and protection: Know your buying power : Shop within your true price range and avoid disappointment. Spot potential roadblocks : Uncover issues like credit bureau errors before you make an offer. Get organized : Learn exactly what documentation you’ll need so there are no surprises. Lock in a rate : Many lenders hold your rate for 30–120 days, giving you peace of mind if rates rise. Save yourself heartache : Protect yourself from falling for a home you can’t afford. Head vs. Heart Buying a home is about balance. Your head tells you what’s financially sound, your heart tells you what feels right—and both matter. A pre-approval helps bring those two sides together, so you can make confident choices without emotional stress clouding your judgment. The Bottom Line Looking at properties for fun is one thing—but if you’re serious about buying, a pre-approval is the smartest first step you can take. It sets realistic expectations, saves time, and protects your emotions along the way. If you’d like to explore your options and get pre-approved, I’d be happy to walk through the process with you. Let’s make sure you’re ready to shop with confidence.
