The case involved Stubart Investment selling its assets to its sister subsidiary Grover in order to use Grover's tax loss carryforwards to offset the profits from the business. The Minister of National Revenue reassessed Stubart, arguing the transaction was a sham to avoid taxes. The Supreme Court of Canada rejected the sham argument and ruled that Stubart was entitled to structure transactions to minimize its taxes. The Court established a new test that a transaction will only be denied for tax purposes if it constitutes an artificial transaction, is abusive, or violates the spirit and purpose of the Income Tax Act. The decision affirmed a taxpayer's right to reduce its tax liability through appropriate legal means.
