The police responded to a 911 call reporting individuals with handguns in a strip club parking lot.
Officers set up a roadblock at the exit and stopped the first vehicle to leave.
The occupants, who matched the general description of the suspects, were asked to exit the vehicle.
One occupant fled, was apprehended, and found to possess a loaded handgun.
The other occupant was subsequently searched, and a loaded handgun was also found on him.
The trial judge admitted the evidence, but the Court of Appeal excluded it, finding violations of ss. 8 and 9 of the Charter.
The Supreme Court of Canada allowed the Crown's appeal and restored the convictions, holding that the initial detention and subsequent searches were justified under the common law police powers and did not violate the Charter.
