Multigenerational Home Renovation Tax Credit

Aging at home is becoming the top choice for many Canadian seniors, and the federal government now offers a powerful new tax credit to help families make that possible. The Multigenerational Home Renovation Tax Credit (MHRTC) can return up to $7,500 to families who build 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.
