The appellant, Opsis Airport Services Inc., is a federal company that operates the emergency call dispatch centre at Pierre Elliot Trudeau International Airport. The respondent the Director of Criminal and Penal Prosecutions charged Opsis with operating an enterprise that carried on private security activities without holding an agency licence of the appropriate class, contrary to ss. 4 and 114 of the Private Security Act, CQLR, c. S-3.5 (“PSA”). Opsis admitted that, without holding an agency licence, it was carrying on activities related to electronic security systems, which are normally subject to the PSA. However, it challenged the PSA’s constitutional applicability.

The Court of Québec held that the PSA applied to Opsis and therefore accepted the guilty pleas, convicted Opsis of the offences as charged and imposed fines on it. The court found that the PSA did not intrude on the core of a federal head of power because the PSA had no impact or only a very small impact on Opsis’s operations. The Superior Court allowed Opsis’s appeal, declared the PSA inapplicable to Opsis’s activities related to the operation of the emergency call centre pursuant to the doctrine of interjurisdictional immunity, quashed the convictions and acquitted Opsis of the offences charged. The judge held that the PSA intruded on the core of the federal aeronautics power, which included airport security, and that the intrusion constituted an impairment of the core of the federal power. A majority of the Court of Appeal allowed the appeal, set aside the Superior Court’s judgment and affirmed the convictions entered by the Court of Québec. Although Opsis’s activities fell within the core of Parliament’s aeronautics power, the application of the PSA did not cause any actual impairment. A purely speculative or hypothetical impairment did not suffice. Ruel J.A., dissenting, would have dismissed the appeal and affirmed the Superior Court’s judgment. He was of the view that if the PSA were applicable to Opsis’s operations, the provisions would impair the core of federal jurisdiction over aeronautics safety and security.
