Quebecor Inc. and its indirect subsidiary, 3662527 Canada Inc., held offsetting tax positions: Quebec faced a $191.8M unrealized gain related to shares it held in Abitibi Consolidated Inc., while 366 had a $200.5M unrealized loss. A series of transactions increased Quebecor’s cost base in its Abitibi shares and moved the loss within its corporate group.
CRA applied GAAR, arguing the series produced multiple losses from the same economic interest and undermined the capital-loss and winding-up rules.
After years of audit, objection, and appeals, the Federal Court of Appeal upheld the Tax Court’s decision and rejected the CRA’s theory, confirming that the result aligned with Parliament’s intention for related-party loss consolidation.
The planners executed the structural steps, but the dispute turned on the taxpayer’s case theory and credibility. The Court evaluated the taxpayer’s account of how the loss actually moved through the group in economic substance and found that the framing aligned with the Act’s underlying design.
The CRA advanced a broad GAAR theory, but the taxpayer’s case theory offered a clear explanation of how the transactions fit within Parliament’s intended treatment of related-party groups. The taxpayer’s success flowed from interpretive credibility – not mechanics.
Reorganizations often present clear financial benefits but also attract CRA scrutiny. Reorganizations often present clear financial benefits but also attract CRA scrutiny. When that scrutiny arrives, a familiar pattern follows: the mechanics set the structure, and the interpretation drives how the CRA and the courts assess the arrangement. CRA frequently grounds its case theory in economic-substance narratives, while courts assess whether the taxpayer’s documented economic rationale aligns with Parliament’s design.
Organizations that advance a credible economic case theory see the dispute revolve around interpretation rather than the mechanics – a dynamic that often meaningfully shifts outcomes.
