Under Canada Revenue Agency (CRA) rules, the Principal Residence Exemption generally applies to a property where the dwelling and adjacent land total no more than 0.5 hectares (approximately 1.24 acres). If the total land area exceeds this threshold, the excess portion is not automatically treated as part of the principal residence for tax purposes.
In certain situations, a larger property may still qualify in full if the owner can demonstrate that the additional land was necessary for the use and enjoyment of the residence — for example, where municipal zoning required a minimum lot size greater than 0.5 hectares at the time of purchase, or where access to a public road required additional adjoining land.
If these conditions cannot be demonstrated, only the portion of land up to 0.5 hectares (1.24 acres) is typically considered eligible for the Principal Residence Exemption, and any capital gain attributable to the excess land may be taxable. This is particularly relevant for rural, acreage, and estate properties where lot sizes commonly exceed the standard exemption threshold.
