Multigenerational Home Renovation Tax Credit: Accessible Bathrooms in Kitchener-Waterloo
What Kitchener-Waterloo Homeowners Need to Know
If you're bringing a parent, grandparent, or adult family member with a disability into your home, the federal government wants to help with the cost. The Multigenerational Home Renovation Tax Credit (MHRTC) is a 15% refundable federal tax credit on up to $50,000 of eligible renovation expenses, meaning you could get as much as $7,500 back when you create a qualifying secondary suite within your existing home.
The MHRTC came into effect for the 2023 tax year. It applies specifically to renovations that create a self-contained secondary unit to house a qualifying individual, which the CRA defines as a senior aged 65 or older, or an adult who is eligible for the Disability Tax Credit. To qualify, the unit must have its own private entrance, sleeping area, kitchen, and bathroom, all distinct from the primary dwelling.
In Kitchener-Waterloo, multigenerational households are increasingly common, driven partly by housing costs and partly by the practical benefits of keeping family close. Adding an accessible bathroom to a secondary suite is one of the most practical ways to trigger MHRTC eligibility, and it's also one of the most meaningful investments you can make for a family member's independence and safety.
This guide is written for homeowners, not tax professionals. Our goal is to help you understand what the credit is, which bathroom renovation costs may qualify, and how to plan a compliant project before you speak with your accountant. Nothing in this article constitutes tax advice. Always confirm your specific situation with a qualified Canadian tax professional or the CRA directly before filing.
The Real Challenges Kitchener-Waterloo Homeowners Face When Adding a Secondary Suite
The concept is straightforward: build a self-contained unit, house a qualifying family member, claim the credit. The reality involves a few more steps, and understanding them before you start will save you time, money, and potential headaches.
The CRA's definition of "self-contained" is strict. The secondary unit must have its own private entrance, sleeping area, kitchen, and bathroom. It can't share a bathroom with the main dwelling and still qualify. That bathroom requirement is non-negotiable, and it's also why the bathroom renovation is such an important expense category for MHRTC purposes.
Ontario's Building Code and local zoning both apply. Under Ontario's Building Code Act, adding a secondary suite requires a building permit. Beyond that, the Region of Waterloo's zoning by-laws govern where secondary suites are permitted, and not every residential zone allows them without a variance application. Completing renovations before confirming zoning compliance is a mistake that can make a project ineligible for the MHRTC if the suite can't legally be occupied. A secondary suite must meet these requirements to qualify for the credit.
The MHRTC and the Home Accessibility Tax Credit (HATC) are different programs. The HATC is a separate non-refundable 15% federal credit on up to $20,000 of eligible accessibility expenses. You may claim both credits in the same tax year for different portions of eligible costs, but you can't apply the same dollar to both credits. Knowing the distinction helps you plan your project scope and documentation strategy alongside your accountant.
Upfront financing is a real barrier for many families. A $30,000 to $50,000 secondary suite renovation isn't a small commitment. The MHRTC is refundable, meaning you receive the credit even if you owe no federal tax, but you still need to fund the project upfront before the credit comes back at tax time. Financing options like Financeit (available through Marble Tradition) can bridge that gap.
Accessibility-specific products add design complexity. Meeting aging-in-place standards in a new secondary suite bathroom, things like grab bar blocking, curbless shower entries, and wider doorways, adds a layer of specification that standard renovation quotes don't always address. Working with a team that understands accessibility solutions from the start keeps the project on track and on budget.
Which Bathroom Renovation Expenses May Qualify Under the MHRTC
The CRA defines eligible expenditures as amounts paid for labour and professional services, building materials, fixtures, equipment rentals, and permit fees directly related to creating the secondary unit. All costs must be reasonable and supported by receipts.
Because the bathroom is a mandatory component of a self-contained secondary unit, a full accessible bathroom installation is among the most clearly eligible expense categories under the program. Here's how common bathroom renovation components fit in:
Shower bases and surrounds. Cultured marble and granite shower bases with curbless or low-threshold designs directly support barrier-free bathroom requirements and count as qualifying fixture expenses when installed as part of a new secondary suite bathroom. Bathtub and shower surrounds made from non-porous, grout-free cultured marble reduce long-term maintenance, meet sanitation standards appropriate for aging-in-place use, and their installation cost forms part of eligible labour and materials. You can also browse custom shower bases sized to fit the exact dimensions of the new bathroom space.
Vanity tops and cabinetry. Vanity tops and bathroom cabinetry installed in the secondary suite bathroom are fixture and material costs that count toward the $50,000 eligible expenditure ceiling.
Shower glass. Shower glass enclosures installed as part of the new bathroom are a qualifying material cost and contribute to a safe, functional shower environment for a senior or person with a disability.
Accessibility-specific upgrades. Grab bar blocking reinforcement, fold-down shower seats, handheld showerheads, and wider doorframes meeting the 32-inch clear-width standard are eligible MHRTC expenditures. These same items may also qualify separately under the HATC, which is why careful expense categorisation matters. Take a look at our gallery of completed projects to see how accessible bathroom features come together in a finished space.
What doesn't qualify. Expenses for renovating the primary dwelling's existing bathroom don't qualify for the MHRTC unless they're structurally necessary to create the secondary unit. The credit applies only to the unit being created, not upgrades to the rest of the house.
DIY labour is not eligible. This is a point many homeowners don't realise until too late. The CRA requires work to be performed by a qualified arm's-length contractor. Your own labour, no matter how skilled, doesn't count as an eligible expenditure under the MHRTC. Professional installation isn't optional here; it's built into the program rules. Browse accessible bathroom renovation options to understand the scope of what a professional installation covers.
How to Plan an MHRTC-Eligible Accessible Bathroom in Kitchener-Waterloo: Step by Step
A well-planned project is much easier to document at tax time. Here's a practical sequence to follow.
Step 1: Confirm zoning before spending anything. Contact the City of Kitchener or City of Waterloo planning department to verify your property is in a zone that permits a secondary suite. This step costs nothing and protects everything. Under Ontario's Building Code, a secondary suite that can't legally be occupied isn't a qualifying unit for MHRTC purposes.
Step 2: Apply for a building permit. This is mandatory for any secondary suite addition. The permit fee itself is an eligible MHRTC expenditure and counts toward your $50,000 ceiling, so keep the confirmation documentation.
Step 3: Get a detailed, itemised written quote. The CRA expects clear documentation of each expense category when you file on Schedule 12 of your T1 return. Your contractor's quote and invoices should separate labour from materials. This isn't just good practice; it's what makes the documentation usable. Use our estimate tool to get a sense of costs before you start comparing contractor quotes.
Step 4: Complete the renovation and track every receipt. Keep contractor invoices, material purchase receipts, and permit fee confirmations organised by date, all tied specifically to the secondary unit. The CRA may request this documentation, and having it ready by category makes the filing process much smoother.
Step 5: Claim on Schedule 12 in the correct tax year. The MHRTC is claimed on Schedule 12 of your T1 personal income tax return for the tax year in which the renovation is completed and the secondary unit first becomes available for use. If your renovation spans a calendar year boundary, discuss the timing with your accountant.
A few more things to know:
Only one qualifying renovation per dwelling is permitted under the MHRTC. If you claim it now for a basement suite, you can't claim it again for the same property in a future year.
Ontario doesn't currently offer a direct provincial equivalent to the MHRTC, but homeowners may also qualify for the Ontario Seniors' Home Safety Tax Credit where applicable. Ask your accountant about stacking federal and provincial credits.
If you're not sure whether your project scope gets you close to the $50,000 eligible expenditure ceiling, getting a professional estimate first lets you think about whether staging work across tax years could be advantageous, another question worth exploring with your accountant.

Frequently Asked Questions: Multigenerational Home Renovation Tax Credit and Accessible Bathrooms
Q: What is the maximum amount I can receive from the Multigenerational Home Renovation Tax Credit?
The MHRTC is a 15% refundable federal tax credit on up to $50,000 of eligible renovation expenses, for a maximum credit of $7,500. Because it's refundable, you receive the credit even if you owe no federal income tax that year.
Q: Does the person moving into the secondary suite have to be the homeowner?
No. The qualifying individual (a senior aged 65 or older, or an adult eligible for the Disability Tax Credit) can be a family member such as a parent, grandparent, or adult child with a disability. They don't need to own the property, but they must ordinarily reside in the secondary unit once it's completed.
Q: Can I claim the MHRTC and the Home Accessibility Tax Credit in the same year?
Yes, you can claim both credits in the same tax year, provided the expenses aren't the same dollars. For example, the structural costs of building the secondary suite bathroom could be claimed under the MHRTC, while the cost of installing a grab bar or walk-in shower modification could be separately claimed under the HATC. Always confirm with your accountant to avoid double-counting.
Q: Does a secondary suite bathroom renovation in Kitchener-Waterloo require a building permit, and does the permit cost count toward the credit?
Yes on both counts. Under Ontario's Building Code, adding a secondary suite requires a building permit from the City of Kitchener or City of Waterloo. The permit fee is an eligible expenditure under the MHRTC and counts toward your $50,000 ceiling. Confirm your specific zoning with the local planning department before starting work.
Q: Do the bathroom products and installation from Marble Tradition count as eligible MHRTC expenses?
Professionally installed fixtures, materials, and labour for a bathroom that forms part of a qualifying secondary suite are eligible MHRTC expenditures under CRA guidelines. Marble Tradition's fully insured team provides itemised invoices covering labour and materials separately, which is the documentation format you need for Schedule 12. Confirm your specific situation with a tax professional before filing.
Q: Can I claim the MHRTC more than once if I renovate my home again in a future year?
No. Only one qualifying renovation per property is permitted under the MHRTC over the lifetime of the program. If you've already claimed the credit for your home, you can't claim it again for the same property in a subsequent year.
Q: Is there an Ontario provincial equivalent to the federal Multigenerational Home Renovation Tax Credit?
As of 2026, Ontario doesn't offer a direct provincial equivalent to the federal MHRTC. However, Ontario homeowners may separately qualify for programs such as the Ontario Seniors' Home Safety Tax Credit. Ask your accountant which provincial credits apply to your situation alongside the federal credit.
Q: What bathroom features should I prioritise to make a secondary suite accessible for a senior?
For a senior moving into a secondary suite, prioritise a curbless or low-threshold shower base for easy entry, grab-bar-ready walls with blocking reinforcement, a handheld adjustable showerhead, non-slip flooring, a wider doorway of at least 32 inches clear width, and a comfort-height vanity. These features support aging-in-place use and may also qualify for the Home Accessibility Tax Credit in addition to the MHRTC. Our accessible bathroom renovation specialists can walk you through the right configuration for your space.
