Will-Kare Paving & Contracting Ltd. v. Canada, 2000 DTC 6467, 2000 SCC 36, [2000] 1 SCR 915 (SCC) -- summary under Class 29

The taxpayer, which paved driveways, parking lots and small roadways, also operated an asphalt-producing plant. 75% of the output was utilized in that paving business, and the balance was sold to third parties. In finding that manufacturing or processing equipment utilized in the plant did not qualify as Class 39 property on the basis that it was not used "primarily in the manufacturing or processing of goods for sale or lease", Major J. noted (at p. 6473) that "the concepts of sale or lease have settled legal definitions", that "Parliament has chosen to use language that imports relatively fine private law distinctions" and that "the technical nature of the Act does not lend itself to broadening the principle of plain meaning to embrace popular meaning". Accordingly, because property and the asphalt transferred to the taxpayer's paving customers as accessions to real property, the equipment did not qualify under Class 39.
