This ruling in *Canada v. CAE Inc.* provides crucial clarification regarding the Tax Court's jurisdiction to issue interim confidentiality orders during discovery.

The Federal Court of Appeal (FCA) recently affirmed a significant ruling by the Tax Court of Canada (TCC) concerning the protection of sensitive information during the discovery phase of tax litigation. In the case of *Canada v. CAE Inc., 2026 FCA 138*, the respondent, CAE Inc., sought an interim confidentiality order to safeguard specific documents that were part of the discovery process. This request arose from the need to protect highly sensitive commercial data.

The documents at the heart of the request included eight bid books and the financial statements pertaining to CAE's subsidiaries and joint ventures. CAE Inc. argued that these materials contained information critical to its operations within a highly competitive and technical industry. Furthermore, some documents incorporated third-party information and were subject to confidentiality clauses, even within the company itself, underscoring their proprietary nature. To support its motion for a protective order, CAE Inc.'s head of financial reporting submitted a detailed affidavit outlining the nature and content of these confidential documents and the specific types of information they contained.

On January 16, 2025, the Tax Court of Canada granted CAE Inc.'s motion, issuing the requested interim confidentiality order. This order applied to two distinct matters, with the understanding that a permanent confidentiality order would be considered by the trial judge at a later stage. The appellant, Canada, subsequently filed two appeals challenging the TCC's decision. These appeals were later consolidated, and one was ultimately discontinued by the parties.

The Federal Court of Appeal proceeded to hear the remaining appeal and ultimately dismissed it, awarding costs against the appellant. This dismissal solidified the TCC's authority to issue such protective measures. The FCA's decision confirmed that the Tax Court had acted within its jurisdiction and that the interim protective order was a proper exercise of its powers in managing complex tax litigation discovery protection.

The Federal Court of Appeal found no legal error in the Tax Court's decision, affirming its jurisdiction to issue the interim confidentiality order. The FCA noted that while the TCC has rarely issued such orders prior to a hearing on the merits, its authority stemmed from Rules 4(1) and 4(2) of the Tax Court of Canada Rules (General Procedure), SOR/90-688a, as well as its inherent power to control its own proceedings. The appellate court determined that the order was neither excessively broad nor based on irrelevant considerations, fitting squarely within the TCC's mandate for proper and expeditious case management.

A key aspect of the FCA's ruling was its affirmation that the Tax Court could issue the interim protective order based solely on the detailed affidavit and the list of documents provided by the respondent, without needing to review the confidential documents themselves. The appellate court concluded that the evidence presented by CAE Inc. was sufficiently detailed to allow the TCC to assess the importance of the information and the necessity for heightened confidentiality measures. The FCA also highlighted that the order effectively balanced CAE Inc.'s significant confidentiality concerns, which extended to third-party information, with the appellant's right to full access to the confidential documents for discovery purposes. Furthermore, the court found no procedural or substantive prejudice to either party, nor any breach of the open court principle, ensuring a fair process. The respondent's reliance on affidavit evidence alone was also deemed not to be a breach of Rule 67 of the Tax Court of Canada Rules.

This ruling in *Canada v. CAE Inc.* provides crucial clarification regarding the Tax Court's jurisdiction to issue interim confidentiality orders during discovery. It establishes a clear precedent for safeguarding sensitive client and third-party information in complex tax litigation, even before a full review of the documents by the court. The decision underscores the importance of submitting detailed affidavit evidence to justify such protective measures, demonstrating the nature and sensitivity of the information at risk. This mechanism offers valuable tax litigation discovery protection, allowing parties to proceed with discovery while ensuring that proprietary and confidential data remains secure, thereby facilitating a more efficient and equitable resolution of disputes.

This ruling clarifies the Tax Court's jurisdiction to issue interim confidentiality orders during discovery, providing a precedent for protecting sensitive client and third-party information in complex tax litigation based on detailed affidavit evidence, even without prior document review. Lawyers should be aware of this mechanism for safeguarding confidential data during the discovery process.
