A police spokesman says the department's guns and gangs unit is combing a suburban area where numerous shots were fired Monday afternoon and a male under 20 was wounded.
Staff Sgt. Patrick McCaffery says the victim was conscious when he was taken to hospital.
The shooting happened about 15 hours after a man was wounded by gunfire at a downtown intersection early Monday morning.
On Boxing Day, a man in his early 20s was shot in the foot at a suburban shopping mall.
Ottawa police have said the mall shooting was a targeted attack involving people associated with the same Crips street gang.
