The accused was charged with weapons offences related to possession of an illegal handgun.
He brought an application to exclude the gun from evidence, alleging that police conduct violated his Charter rights.
The officer stopped the accused based on suspicion that he might be one of two Fountain brothers, one of whom might be wanted.
After clarifying the accused's identity and confirming no warrants existed, the officer continued to detain the accused to complete a field investigative report (FIR card).
When a third party suddenly interjected, the accused's demeanor changed and he adopted a blading stance.
The officer, concerned for safety, conducted a pat-down search and discovered the gun.
The court found an unlawful detention during the FIR process but held that the pat-down search was lawful as it was conducted in response to exigent circumstances triggered by the accused's sudden threatening posture.
The gun was admitted into evidence under section 24(2) of the Charter.
