Canada Post Corporation brought an application for an injunction to restrain the appellant from violating its exclusive privilege to collect and deliver international mail under section 14(1) of the Canada Post Corporation Act.
The appellant argued that the Act provided a complete code with specific penalties, precluding civil proceedings, and raised equitable defences of laches, delay, and estoppel.
The Court of Appeal held that Canada Post has the right to seek an injunction to enforce its statutory privilege, as the penalty provisions alone are insufficient to protect its mandate.
The Court further held that equitable defences cannot be raised against a Crown agent to prevent the operation of a public policy statute.
The appeal was dismissed.
