HAMILTON -- Ray Emery, the former NHL goaltender whose career spanned more than a decade and included stops in Ottawa, Chicago and Philadelphia, drowned in Hamilton Harbour on Sunday, police said.

Insp. Marty Schulenberg said Emery's death does not appear to be suspicious, calling it a "case of misadventure."

Schulenberg said Emery jumped off of a boat into the water near the Leander Boat Club to go swimming, and his friends called emergency services at about 6 a.m. Sunday when he didn't resurface.

Emery, 35, played for several teams throughout his 11-year career, winning the William M. Jennings trophy -- and the Stanley Cup -- with the Blackhawks in 2013.

The rare goalie who didn't hesitate to drop his gloves, Emery was involved in multiple altercations on the ice, including one in 2007 in which he scuffled with Buffalo Sabres goalie Martin Biron.

Biron was among those mourning Emery online Sunday.

"So sad. Thoughts and prayers to his family and friends," he wrote on Twitter.

Schulenberg said Emery's body was found at about 2:50 p.m. Sunday, about 20 metres from where he went into the water. He said a post mortem will be completed on Monday.

"Mr. Emery was taking a swim this morning and the circumstances around that are a part of the investigation," said Schulenberg.

"Those details remain to be uncovered by our investigators."

Schulenberg said first responders were not able to locate Emery right away, and so they called in the dive unit. He said the search took longer than anticipated because they had to ensure the safety of the dive team.

"It's a lengthy process and safety is paramount to our divers," he said. "We need to take the time do it safely and that's what the delay was."

Several members of the NHL community, including former teammates, coaches and executives who played and worked with Emery expressed their condolences for the Hamilton native.

Current Flyers captain Claude Giroux posted on Twitter: "Ray was a great teammate and an even better friend. Rest in peace Razor. I'll miss you man."

Emery played junior hockey for the Sault Ste. Marie Greyhounds, where Toronto Maple Leafs GM Kyle Dubas began his career. Dubas posted about Emery's death on Twitter Sunday afternoon.

"Ray's smile and intelligence made him a magnetic personality," Dubas wrote. "You always rooted for him to reach his vast potential, even as he went through the many ups and downs of his playing career."

Former Leafs forward James van Riemsdyk, who played with Emery in Philadelphia, said on Twitter: "So sad to hear the tragic news about Ray Emery -- was a great teammate and person."

Ottawa Senators owner Eugene Melnyk also released a statement expressing condolences.

"Ray was instrumental in our run to the 2007 Stanley Cup Final, and at his best he brought a competitive edge and combative mentality to the game. On behalf of our entire organization, I wish to extend my deepest sympathies to Ray's family, friends and loved ones," said Melnyk.

Emery battled avascular necrosis, the same serious hip ailment that ended two-sport star Bo Jackson's career, and came back to play. He and fellow Blackhawks netminder Corey Crawford combined to win the Jennings Trophy for allowing the league's fewest goals during the lockout-shortened 2013 season.

Throughout his career, Emery dealt with off-ice problems, including an incident of road rage, assault of a trainer in Russia and behaviour that led to him being sent home from Ottawa's training camp.
