Dupont Canada Inc. v. Canada, 2001 DTC 5269, 2001 FCA 114 -- summary under Subsection 1101(1)

A sale by the taxpayer of most of the assets of its explosives manufacturing operation in Nipissing was found not to be a sale of a separate business in light of the fact that such division and other manufacturing operations were operated through the provision (principally in Mississauga) of centralized services, including all borrowing and financing, cash management, foreign exchange management, the granting of credit, invoicing of customers, collection of accounts, purchasing, processing of supplier invoices and preparation of expense reports. It also was important that the Du Pont brand name and trade marks were used consistently for all of the taxpayer's products, but they ceased to be an attribute of the explosives manufactured at the explosives plant after the sale. Because the depreciable assets that were sold were included in the same class as depreciable assets retained by the taxpayer, the recaptured capital cost allowance realized by the taxpayer was reduced accordingly.
