The MHRTC is a recently introduced refundable tax credit enabling eligible individuals to recoup specific renovation expenses incurred in establishing a secondary unit within a qualifying residence. This unit is intended for a qualifying individual, such as a senior or an adult eligible for the disability tax credit, to live with their eligible relative. If you meet the criteria, you can claim up to $50,000 for each eligible renovation completed, with a maximum credit of $7,500 per qualifying claim.
