for an eligible person (generally a relative either age 65 or over, or eligible for the disability tax credit) to live with a qualifying relation. The tax credit is available on up to $50,000 of eligible expenditures incurred after 2022 at a rate of 15%.

In a March 6, 2023 Technical Interpretation, CRA confirmed that the eligible person must ordinarily inhabit, or be intended to ordinarily inhabit, the new dwelling unit constructed, but does not have to reside with the qualifying relation before the renovations are undertaken.

In a second March 6, 2023 Technical Interpretation, CRA was asked whether the construction of a separate, detached housing unit on the same parcel of land as a principal housing unit, such as a carriage house or laneway house, would be eligible. CRA noted that a qualifying renovation must enable the qualifying individual to reside in the dwelling by establishing

a secondary unit within the dwelling. CRA indicated that
a second detached housing unit located on the same parcel of land as the primary dwelling unit would be considered to be located within the dwelling (that is, the dwelling would be considered to include the subjacent land) and would qualify for the credit.
