None of the people involved was hit by gunfire.
The shooting took pace near the corner of St-Laurent Boulevard and Fleury Street.
Police Constable Danny Richer said two men in their 60s were in a fight when one of the men pulled out a gun and fired at the other.
The victim was not hit by the gunshot, but was, nevertheless, taken to hospital to be examined.
Richer said investigators have met with the victim and with witnesses.
Police have not located the suspect, or the firearm.
