How to Apply for the Canada Secondary Suite Loan Program in Ottawa

The Canada Secondary Suite Loan Program is a federal initiative offering eligible homeowners up to $80,000 in financing at 2% interest to create a new secondary suite within their existing home or on their property. For Ottawa homeowners considering a basement apartment, garden suite, coach home, or laneway home, this program can significantly reduce the upfront cost of the project.

This guide covers who qualifies, what types of suites are eligible, how to apply, and how the loan interacts with Ottawa's permit process and zoning rules.

What Is the Canada Secondary Suite Loan Program?

The Canada Secondary Suite Loan Program (CSSLP) is administered through Canada Mortgage and Housing Corporation (CMHC) and was introduced as part of Canada's broader housing affordability strategy. The program provides low-interest loans to homeowners who add new secondary suites to increase housing supply in their communities.

Key program details:

• Maximum loan amount: $80,000 per eligible homeowner
• Interest rate: 2% fixed
• Repayment term: Up to 15 years
• Purpose: To finance the construction of a new secondary suite that will be used as a long-term rental unit
• Administering body: CMHC, through participating lenders

What Types of Suites Are Eligible?

The program covers new secondary suites added to existing residential properties. Eligible suite types include:

• Basement apartment / in-home secondary suite: A self-contained unit within the existing home with its own entrance, kitchen, bathroom, and living space. See our guide on how to add a kitchen to your basement.
• Garden suite / laneway home: A detached dwelling unit in the rear yard of the property
• Coach home: A dwelling unit above a detached garage. See cost to build a coach home in Ottawa.
• ADU (Accessory Dwelling Unit): Any self-contained unit added to an existing residential property. See cost to build an ADU in Ottawa.

The suite must be a new addition — the program does not fund renovations to existing legal secondary suites. It must be built as a rental unit, not for personal family use.

Who Qualifies for the Program?

To be eligible for the Canada Secondary Suite Loan Program, applicants must:

• Be a Canadian citizen, permanent resident, or non-permanent resident authorized to work in Canada
• Own and occupy the primary residence as their principal home
• Meet the income and creditworthiness requirements of the participating lender
• Commit to renting the secondary suite as a long-term rental (not short-term/Airbnb)
• Ensure the secondary suite is legal under local zoning and building code requirements

In Ottawa, the suite must comply with the City's zoning by-laws and the Ontario Building Code. Under Ottawa's 2026 zoning by-law, secondary suites are permitted as-of-right in most residential zones — see Ottawa's new zoning by-laws for details. The suite must also obtain all required permits — see our guides on basement renovation permits and how to get a building permit in Ottawa.

What Costs Are Covered?

The loan can be used to cover eligible construction costs for the secondary suite, including:

• Construction and renovation labour
• Materials and finishes
• Permits and inspection fees (including Ottawa building permit fees)
• Architectural and design fees
• Plumbing, electrical, and HVAC installation
• Kitchen installation (see basement kitchen permit guide)
• Utility connection costs (see connecting utilities to your backyard suite)

The loan cannot be used for the primary dwelling's costs, land acquisition, or non-construction expenses.

How to Apply: Step by Step

1. Confirm your eligibility. Review the program requirements on the CMHC website and confirm your property qualifies under Ottawa's zoning by-laws.
2. Get quotes from licensed contractors. You'll need detailed construction cost estimates to support your application. At Ottawa General Contractors, we provide detailed quotes suitable for CMHC program applications.
3. Contact a participating lender. The loan is administered through CMHC-approved financial institutions. Contact your bank or mortgage lender to ask about participation in the program.
4. Submit your application. Applications are submitted through the participating lender, who forwards to CMHC for approval. Provide construction quotes, property information, and income documentation.
5. Receive conditional approval and begin construction. Upon approval, funds are typically disbursed in stages tied to construction milestones.
6. Obtain all required permits and complete inspections. The suite must pass all required building inspections to satisfy program requirements.
7. Begin renting and repaying. Repayment begins after construction is complete.

How the Loan Affects Your Finances

A $80,000 loan at 2% interest over 15 years results in monthly payments of approximately $515. If the secondary suite rents for $1,500–$2,000/month (typical Ottawa rental rates for a one-bedroom basement suite or garden suite), the rental income more than covers the loan repayment while providing ongoing positive cash flow.

The net financial benefit: rental income offsets both the loan repayment and a portion of your primary mortgage, while the secondary suite permanently increases your property's value.

Ottawa-Specific Considerations

In Ottawa, secondary suite construction must comply with the Ontario Building Code and the City's zoning by-laws. Key Ottawa-specific requirements for CSSLP eligibility:

• The suite must obtain a building permit from the City of Ottawa — see Ottawa permit fees for 2026
• The suite must pass all required building inspections (structural, mechanical, final)
• The suite must comply with the 2026 Zoning By-law — check your zone at how to check your zoning classification
• If the suite is a detached structure (garden suite, coach home), utility connections must be properly permitted — see connecting utilities to your backyard suite
