The appellant challenged the vires of the Federal Child Support Guidelines, enacted by the Governor in Council under the Divorce Act, arguing that the GIC exceeded its authority because the Guidelines require the payer parent to bear a greater share of child-related costs than the recipient parent.

The Supreme Court held that the reasonableness standard under the Vavilov framework presumptively applies when reviewing the vires of subordinate legislation, and that the 'irrelevant, extraneous or completely unrelated' threshold from Katz Group is no longer good law.

Applying reasonableness review, the Court concluded that the Child Support Guidelines fall within the GIC's extremely broad statutory authority under s. 26.1 of the Divorce Act and are therefore intra vires.

The appeal was dismissed with costs.

In multiple applications for judicial review challenging the 2020 firearms ban regulations, the applicants sought documentary disclosure from the Governor in Council under Rule 317 of the Federal Courts Rules.

The respondent objected on the basis of Cabinet confidentiality but failed to issue a certificate under section 39 of the Canada Evidence Act.

The Court held that without a valid certificate, the statutory absolute protection from review was not triggered.

Instead, the common law applied, requiring the Court to review the documents to balance the public interest in disclosure against confidentiality.

The Court ordered the respondent to file the materials under seal for the Court's review.

The Applicants sought leave under Rule 302 of the Federal Courts Rules to pursue judicial review of multiple decisions in respect of which relief is sought, specifically challenging up to 600 individual technical opinions made by the RCMP adding firearms to the Firearms Reference Table.

The Court dismissed the motions, finding the Applicants failed to specify which technical opinions they wanted to review, thereby running afoul of Rule 301(c)(ii) and preventing the Court from determining the matters under review or exercising its discretion to make a Rule 302 exception.

The applicants sought an interlocutory injunction staying the operation of regulations prohibiting certain firearms pending the outcome of their applications for judicial review.

The Federal Court dismissed the motions, finding the applicants failed to demonstrate with clear and non-speculative evidence that they would suffer irreparable harm without the injunction.

The appellants challenged the legality of the Federal Child Support Guidelines through judicial review in the Federal Court.

The Supreme Court held that provincial superior courts can address the validity of the Guidelines when necessary in proceedings properly before them, and that the Federal Court reasonably exercised its discretion to decline judicial review because that route was not appropriate in the circumstances.

The appeal was dismissed, with concurring reasons cautioning against treating the case as a definitive ruling on exclusive federal jurisdiction to invalidate all federal regulations on administrative grounds.
