Police in Quebec are hunting for a convicted murderer who escaped from a prison in Laval, north of Montreal, early Tuesday.
Robert Gaudette was discovered missing during a head count at the Federal Training Centre, which is listed as both a minimum and medium security facility.
The Correctional Service of Canada immediately contacted the RCMP, Quebec provincial police and the local force in Laval.
Gaudette, who is 55, has been behind bars since receiving a life sentence in 2002 for the second-degree murder of his wife.
He is five-foot-11, 189 pounds with a pale complexion, green eyes and brown hair, and has a surgical scar on the abdomen.
The Correctional Service says it will conduct an investigation into the circumstances surrounding the escape.
Earlier this year three men escaped from the Orsainville Detention Centre in Quebec City with the help of a helicopter.
That was the second time in just over a year that a helicopter was involved in a jailbreak.
