This appeal considered whether a municipal notice of reserve that blocked construction at a federally approved antenna site was constitutionally valid.

The majority held the notice’s pith and substance was the siting of radiocommunication infrastructure, an exclusive federal matter, making it ultra vires.

The Court also held the measure significantly impaired the federal core protected by interjurisdictional immunity.

The appeal was allowed and the notice was unconstitutional and inapplicable to the appellant.

The Court allowed the appeal, holding that authorization under s. 225.4 of Quebec’s Securities Act requires a realistic chance of success and that the respondent failed to show credible evidence of a material change triggering timely disclosure obligations.

On a motion in related leave applications, the moving parties sought an order requiring multiple opposing parties to post $3,250,000 as security for amounts payable if appeals were unsuccessful.

The Court held that security under s. 60(1)(b) of the Supreme Court Act has traditionally been symbolic and that the substantial security requested is ordinarily addressed in stay proceedings under ss. 65 or 65.1 or equivalent provincial provisions.

The Court found that existing stay conditions imposed by the court below continued to govern and that the motion effectively attempted to review that decision.

The Court also emphasized access-to-court considerations in the leave framework.

The motion was dismissed without costs.
