Leveque split 1992–93 and 1993–94 between the Kings and the IHL's Phoenix Roadrunners. He spent much of 1994–95 with the Canada national men's ice hockey team, but also spent some time with the Roadrunners and the St. John's Maple Leafs of the American Hockey League. He spent the entire 1995–96 season with the Manitoba Moose, the 1996–97 season with the San Antonio Dragons, and 1997–98 with the Phoenix Mustangs of the West Coast Hockey League before finally retiring from professional hockey.
Leveque was a member of the Los Angeles Kings during the 1993 Stanley Cup Playoffs. Led by Wayne Gretzky, the Kings made the final against the Montreal Canadiens. Leveque was forced to sit out the final with an injury.
Leveque was found drowned to death in a pool of water in St. Catharines, Ontario on October 2, 2005. Police estimated date of death as September 27. Police have remained baffled by the death, but it was known by family that Leveque suffered from an OxyContin addiction that developed through usage for back pain that had plagued him since junior hockey and that he suffered from bouts with depression.
