CMHC's Secondary Suite Loan Program: a new era for single-family homes
4 Foreever Renovation team,

As housing costs continue to rise across the GTA, a government initiative is changing how we think about single-family homes. At 4 Foreever Renovation, we're excited to share the details of the expanded CMHC Secondary Suite Loan Program, a solution that addresses both housing affordability and the changing needs of Canadian families.
Reimagining single-family homes
Many homeowners, particularly retirees, have more space than they need while still paying to heat, cool, insure and tax the unused space. Secondary suites solve that problem, bringing gentle density to our neighbourhoods while making homeownership more affordable.
What are secondary suites?
Secondary suites can take several forms:
- Basement rental apartments
- In-law suites for multi-generational living
- Laneway homes for downsizing or rental income
- Converted garage spaces
Program details and benefits
The expanded program, announced for early 2025, offers two financing options that can be used together:
1. Secondary Suite Loan Program
- Loan limit increased to $80,000
- 15-year loan terms
- Low 2% interest rate
- Administered by CMHC
2. Mortgage insurance reforms
- Access up to 90% of the post-renovation home value
- Maximum property value of $2 million
- 30-year amortization periods available
- Available starting January 15, 2025
Multi-generational living
Secondary suites give families flexible ways to live together. For example:
- Retired parents can downsize into a new laneway home while their children raise a family in the main house
- Adult children can create an in-law suite for aging parents
- Homeowners can earn rental income to help with mortgage payments
- Families can stay together while keeping their privacy and independence

Planning a secondary suite?
We can look at your basement or lot, tell you what a legal unit would need, and help you prepare the designs and permits so you're ready to apply for financing.
Community benefits
A secondary suite does more than help one household:
- Increases housing supply in established neighbourhoods
- Adds gentle density without changing a neighbourhood's character
- Creates more affordable options for renters
- Supports multi-generational living
