The 52-year-old man shot and killed at a plaza in Burlington Friday afternoon has been identified by Halton police as Hamilton mobster Pasquale (Pat) Musitano.

At around 1:10 p.m., Halton Regional Police responded to a shooting at 484 Plains Road East.

A short time later, police confirmed that Musitano died of his injuries. Two others were transported to hospital, one of them with serious to critical injuries, police said.

The third man had undetermined injuries and it is not yet clear whether he was struck by gunfire.

At least one suspect fled the scene in a vehicle and is currently outstanding.

The vehicle is described as a newer model grey four-door sedan, similar to an Infiniti Q50 with a sunroof. Police say the vehicle will have fresh damage to the driver's side.

No detailed suspect description is available so far.

Constable Ryan Anderson told reporters at the scene that it’s too early to say what led to the killing.

“I can’t speculate on any sort of motive. It’s extremely early right now,” he said.

Investigators are asking anyone with information or with surveillance or dashcam footage from the area to contact police.

Plains Road East is currently closed in both directions between King Road and Waterdown Road as police investigate.

“Our investigators are going to be doing an extensive investigation – canvassing the area for cameras, that sort of thing. It requires a large road closure at this point and a large scene for our officers to conduct their investigation,” Anderson said.

“Residents can expect a heavy police presence here for the foreseeable future.”

There is not believed to be any immediate threat to public safety, police said, but people are being asked to avoid the area. 

In April 2019, Musitano was critically injured after he was shot at a parking lot in Mississauga while leaving his lawyer's office.

His 39-year-old brother, Angelo, was shot to death in May 2017 while sitting in a pickup truck parked in the driveway of his home in Waterdown.

One male suspect was arrested, and two others remain outstanding in connection with Angelo's fatal shooting.

The brothers were charged with first-degree murder in the 1997 contract killing of Hamilton mob boss Johnny "Pops" Papalia.

A plea bargain allowed the brothers to plead guilty to the lesser offence of conspiracy to commit murder in the shooting death of Niagara crime boss Carmen Barillaro in 1997.

The brothers were sentenced to 10 years behind bars in 2000 and were released from prison in 2006.
