164. Notwithstanding section 160, no amount shall be deducted by a taxpayer in computing his income for a particular taxation year in respect of an expense incurred by him in the year as, or in lieu of, full or partial payment of interest on debt relating to the acquisition of land or as, or in lieu of, full or partial payment of property taxes paid or payable by him in respect of land to a province or to a Canadian municipality, except to the extent of the amount determined in the second paragraph, unless, having regard to all the circumstances, including the cost to the taxpayer of the land in relation to his gross revenue therefrom for the particular year or any preceding taxation year, the land can reasonably be considered to have been, in the year,(a) used in the course of a business carried on in the particular year by the taxpayer, other than a business in the ordinary course of which land is held primarily for the purposes of resale or development, or
(b) held primarily by the taxpayer for the purposes of gaining or producing income therefrom for the particular year.
The amount referred to in the first paragraph is equal to the aggregate of(a) the amount by which the taxpayer’s gross revenue from the land for the particular year exceeds the aggregate of all other amounts deducted in computing his income from the land for the year;
(b) where the taxpayer is a corporation whose principal business is the leasing, rental or sale, or the development for lease, rental or sale, or any combination thereof, of immovable property owned by it, to or for a person with whom it is dealing at arm’s length, the corporation’s base level deduction for the particular year.
