During the 2010 G20 summit in Toronto, the appellant and his friends were walking down a public street intending to demonstrate in support of animal rights.
They were stopped by police officers who demanded to search their bags as a condition of proceeding further.
The appellant refused and was grabbed and pushed by an officer.
The Court of Appeal held that the police conduct was not authorized by the common law ancillary powers doctrine, as it was not reasonably necessary to preserve the peace.
The court found that the police violated the appellant's common law right to travel unimpeded and his freedom of expression under s. 2(b) of the Charter.
The court also held that the officer committed the tort of battery, as he lacked lawful authority and the contact was unnecessary.
