Executive Summary: Key Legal and Evidentiary Issues

• A corporation’s appeal of a municipal tax assessment was rejected for being filed outside the statutory deadline under the Municipal Taxation Act.

• The Tribunal administratif du Québec improperly relied on a discretionary provision in the Justice Administrative Act to accept a late appeal.

• The court emphasized that specific tax law deadlines override general administrative discretion provisions.

• The notice of appeal was filed by an accountant unaffiliated with the company as an officer or member of the Barreau du Québec, violating the Bar Act.

• Such unauthorized representation rendered the appeal procedurally invalid from the outset.

• The court annulled TAQ’s decision and confirmed that strict compliance with tax appeal rules is mandatory.

Facts of the case

In 9121-6788 Québec inc. v. Ville de Montréal, the plaintiff, a corporation, sought to contest a property tax assessment issued by the City of Montréal for a non-residential property. The challenge was governed by the Loi sur la fiscalité municipale (Municipal Taxation Act), which requires filing a notice of appeal to the Tribunal administratif du Québec (TAQ) within 60 days of the decision being contested. The corporation missed this deadline and attempted to justify the delay based on difficulties communicating with the City and confusion over procedures.

Despite the missed statutory deadline, TAQ agreed to hear the case by invoking article 106 of the Loi sur la justice administrative, which permits procedural flexibility where reasonable grounds are shown. TAQ accepted the corporation's explanation for the late filing and proceeded with the matter. However, it was later revealed that the notice of appeal had not been filed by a lawyer or an officer of the corporation, but by an external accountant. This raised serious questions about unauthorized legal practice.

Court’s analysis and findings

The Court of Québec reviewed whether TAQ had the jurisdiction to extend a mandatory deadline under the Municipal Taxation Act by invoking general discretion found in the Justice Administrative Act. The court emphasized the legal principle that specific statutes prevail over general ones. The Municipal Taxation Act provides a clear and fixed 60-day deadline for appeals, and it contains no clause permitting exceptions or extensions. Therefore, article 106 of the Justice Administrative Act could not override this stricter, more specific rule.

In addition, the court addressed the procedural validity of the appeal. The notice of appeal had been filed by the corporation’s accountant, who was neither a member of the Barreau du Québec nor an authorized officer of the company. The court held that this contravened the Loi sur le Barreau (Bar Act), which strictly limits the legal representation of others to licensed lawyers or qualified in-house representatives. Because the individual who filed the notice lacked the legal authority to act on the corporation’s behalf, the appeal was invalid from the outset.

The court found that TAQ erred both in accepting the late filing and in failing to address the unauthorized legal representation. These were not curable defects but went to the heart of TAQ’s jurisdiction to hear the matter at all.

Outcome and procedural posture

The Court of Québec allowed the appeal filed by the City of Montréal and annulled the TAQ’s decision in its entirety. The corporation’s appeal of its tax assessment was declared inadmissible due to both the late filing and the unauthorized practice of law by its representative. The judgment reinforces the strict procedural framework applicable to municipal tax disputes in Quebec and confirms that such timelines and representation rules are not flexible or subject to equitable discretion.
