One man is dead after he was shot outside a wedding reception where a fight had broken out, in St-Leonard early Sunday morning. 

The 29-year-old man was found sprawled on the street with a gunshot wound when police arrived at around 1:15 a.m. in the borough of Saint-Leonard. 

Police say they received 911 calls from several witnesses about the fight at reception hall near the corner of Provencher Boulevard and Denis Papin Street. 

Gunshots were heard, but the suspect fled. When emergency crews responded it was too late for the man, who was wounded in his upper body.

A witness told reporters the fight had started at a wedding reception inside Le Madison hall, before spilling onto the street.

But Montreal spokesperson Const. Manuel Couture said investigators were looking into the connection between the fight and the shooting because they received conflicting reports.

"That's what they're looking at right now. Is it related or is it a coincidence that the man was shot at the same time that the fight happened?" Couture said.

The SPVM's major crimes unit is investigating and has erected a perimeter, closing Provencher between Roquebrune and Enrico-Fermi streets.

The canine unit was also dispatched to the scene.

It is Montreal's 13th homicide of 2017.
