Multigenerational Home Renovation Tax Credit

More Canadian seniors are choosing to age at home, and the federal government is making it easier with a generous new tax credit. The Multigenerational Home Renovation Tax Credit (MHRTC) offers up to $7,500 back to families who create a secondary suite for a senior or an adult with a disability.

This guide explains what the credit is, who qualifies, what renovations count, how to apply, and how to maximize your refund.

What Is the Multigenerational Home Renovation Tax Credit?

The MHRTC is a refundable federal tax credit that helps families create a self‑contained secondary unit so a senior (65+) or a person eligible for the Disability Tax Credit can live with a qualifying relative.

Because it is refundable, you receive the money even if you owe no taxes.
