Federal Court Allows Lawsuit Challenging Capital Gains Tax Hike to Move Forward
In a significant ruling, a federal court has permitted a lawsuit contesting the Canada Revenue Agency’s (CRA) premature enforcement of a capital gains tax increase to proceed. This decision underscores a critical constitutional debate over Parliament’s exclusive authority to impose new taxes, potentially shaping future tax policies in Canada.
Background of the Tax Hike
In June 2024, the federal government proposed raising the capital gains inclusion rate from 50% to 67% for individuals, businesses, and trusts with over $250,000 in annual capital gains. Aimed at increasing revenue and ensuring greater contribution from wealthier entities, the change was set to apply from June 25, 2024, regardless of agreement signing dates.
However, by January 2025, the legislation remained unpassed due to Parliament’s prorogation. The CRA began enforcing the higher rate, prompting legal challenges from taxpayers and advocacy groups like the Canadian Taxpayers Federation (CTF), who argued this action violated constitutional democracy.
The Legal Challenge
A lawsuit initiated by an Ontario resident and a B.C. company alleged CRA’s enforcement was unconstitutional, citing Section 53 of the Constitution Act, 1867. This section mandates parliamentary approval for tax increases. The Attorney General sought dismissal, but the court ruled the challenge merited judicial review due to its serious constitutional implications.
“This ruling is a win for Canadian taxpayers as it allows our constitutional challenge to proceed,” stated Devin Drover, CTF’s general counsel. “It defends the principle that tax increases must be debated and approved in Parliament, not imposed by unelected officials.”
Significance and Implications
The case holds profound implications for Canada’s tax policy and democratic processes. It revolves around the constitutional principle of “no taxation without representation,” a cornerstone of Canadian democracy. If successful, the lawsuit would reinforce Parliament’s sole authority over taxation, curbing governmental overreach in future tax measures.
Constitutional Principle
The lawsuit underscores the importance of Section 53 of the Constitution Act, 1867, which requires parliamentary approval for tax increases. A favorable ruling would reaffirm that tax changes must be debated and approved by elected representatives, not imposed by unelected officials.
Taxpayer Uncertainty
The situation has caused confusion among taxpayers, who may face the higher tax rate before Parliament’s approval. If the proposal is later rejected, reclaiming overpaid taxes could become a complex and cumbersome process for affected individuals and businesses.
Future Precedent
The plaintiffs aim to set a legal precedent, preventing future governments from bypassing Parliament to enact tax increases. This would ensure that any future tax policies adhere to constitutional requirements, maintaining democratic integrity.
Government Response
The CRA has refrained from commenting on the ongoing litigation, reflecting its policy of not discussing active legal cases. This stance highlights the sensitivity and potential impact of the case on future governmental operations.
Recent Developments
Following the lawsuits, the government deferred the capital gains tax increase to 2026 and later withdrew it ahead of the federal election in April 2025. Despite this, the core constitutional issue remains unresolved, now under judicial review. The court’s decision to allow the case to proceed ensures that the critical question of administrative power in taxation will be addressed, potentially influencing future policy enforcement.
Conclusion
The ongoing lawsuit challenging Canada’s tax policy underscores the delicate balance between governmental authority and democratic processes. By focusing on the constitutional principle of “no taxation without representation,” the case highlights the importance of parliamentary oversight in taxation matters. The deferment and withdrawal of the capital gains tax increase, while providing temporary relief, do not resolve the core constitutional issue. The court’s decision will set a critical precedent, potentially shaping the future of tax policy enforcement and ensuring adherence to democratic principles.
