Introduction
Hey Mike, thinking about claiming Canada’s new Multigenerational Home Renovation Tax Credit (MHRTC)? It’s a great move if you’re creating a cozy space for aging parents, a disabled relative, or grown kids who need a place to land. But here’s something you might not have considered: how does this affect your Principal Residence Exemption (PRE)—the one that usually lets you sell your home tax-free?
Below, we’ll break down the MHRTC, the PRE, and how your future use of that newly created living space can influence your tax outcome when you eventually sell.
What Is the Multigenerational Home Renovation Tax Credit (MHRTC)?
The MHRTC is a Canadian tax credit that offers up to $7,500 if you spend $50,000 on eligible renovations. It’s all about encouraging multigenerational housing—think retrofitting your home to accommodate a parent, grandparent, or a family member with a disability. It’s a serious financial win for families looking to stay together under one roof.
Understanding the Principal Residence Exemption (PRE)
The Principal Residence Exemption is a cornerstone of Canadian homeownership. When you sell a home that’s been your principal residence every year you owned it, the capital gains are usually tax-free. That’s huge, especially with property values trending upward.
Will Claiming the MHRTC Automatically Affect Your PRE?
Short answer: No, not automatically. The simple act of claiming the MHRTC to modify your home for family use does not directly threaten your PRE. As long as the newly renovated space remains part of your personal living area and is used by family members, you retain your full principal residence status. Your capital gains—when you sell—stay comfortably sheltered under the PRE.
The Catch: Turning Your Space Into a Rental
Here’s where the PRE can hit a snag: If, after setting up that multigenerational suite, you decide to rent it out to non-family tenants, you shift the property’s use from personal to income-producing. The Canada Revenue Agency (CRA) views that rented portion as a commercial segment of your home, no longer qualifying as part of your principal residence.
What does that mean come sale time? When you sell, you’ll likely need to apportion your property’s capital gain between the principal residence portion and the income-producing portion. The rental side may trigger taxable capital gains, reducing the PRE’s benefits.
Protecting Your PRE and Maximizing the MHRTC
Keep it in the Family: To maintain your full PRE, continue using the secondary suite for family members. Avoid turning it into a separate, for-profit rental unit.
Document Everything: If you ever need to confirm that the space was part of your personal residence, detailed records help. Keep renovation receipts, note who lived there and when, and maintain clear documentation of your family’s living arrangements.
Weigh the Trade-Offs: Before you rent that suite out on Airbnb or to a tenant, consider the tax implications. The immediate rental income might be tempting, but long-term tax costs on capital gains could outweigh the short-term gain.
Consult a Tax Professional: Navigating the MHRTC and PRE can be complex. A Canadian tax expert can help you understand the fine print, project tax scenarios, and ensure you’re maximizing all available benefits without jeopardizing your PRE.

By staying informed, keeping your renovations family-focused, and talking to a tax professional, you can enjoy the best of both worlds: support for your multigenerational family and the long-term tax benefits that come with maintaining your PRE.
Stay savvy, Mike, and happy renovating!
