Police and paramedics were called late Sunday night after a woman and a man were injured by a gunman.
When police arrived on Cardinal St. in the borough of St. Laurent they found an 18-year-old woman and 21-year-old man lying on the sidewalk.
The two victims were transported to hospital with non-life-threatening injuries to the lower body said Const. Jean-Pierre Brabant.
"They were conscious during their transport," said Brabant, adding they were not very coherent, "so it's hard to know what happened."
A 911 caller reported hearing multiple gunshots, possibly as many as six.
"Was it a drive-by shooting, was it someone that came by foot to approach them and shot them after? That's what investigators are going to try to figure out," said Brabant.
Brabant said a cause for the shooting has not been established.
Police later said the 21-year-old man who was shot was known to officers. The female victim is 18 years old.
No arrests have been made.
The investigation is ongoing.
