Aimé Simard was born in 1968 in Quebec City, Canada. A physically strong man and self-identified tough guy, he once aspired to become a police officer. He studied accounting, management, and police administration at university. However, his future in law enforcement was derailed due to a lengthy criminal history—80 convictions for petty crimes such as shoplifting, fraud, and threats.

After serving time in prison for uttering death threats, Simard relocated to Montreal. Despite portraying himself as a straight man publicly, he was secretly in a relationship with Dany Kane, a fellow contract killer and Rockers Motorcycle Club member. Their relationship, which began in November 1996, was kept hidden due to Kane's status as a married man with children. Simard had met Kane on a gay dating site, and they quickly became involved—both romantically and criminally.

Kane, who was also a police informant for the RCMP, sponsored Simard into the Rockers, a puppet club for the Hells Angels. Simard was reckless and aggressive, the opposite of Kane's cautious and calculating personality. Despite their differences, they worked closely together on murder contracts handed down by the Hells Angels, particularly Nomad leader David "Wolf" Carroll. Kane used Simard not only for crime but also as his personal driver, often relying on him to attend secret RCMP meetings while his wife remained unaware of their relationship.

Simard's first known killing occurred on February 27, 1997, when he and Kane were ordered to murder Robert MacFarlane, a rowdy Halifax businessman who had become a liability to the Hells Angels. The pair followed MacFarlane from his workplace to an industrial park, where Simard shot him in the neck and killed him while Kane fired two intentionally missed shots to maintain deniability with his RCMP handlers. Security footage recorded the murder, but poor video quality made identification difficult.

Shortly after, Simard shot a drug dealer and his girlfriend in Quebec City in an apparent dispute over money owed to the Rockers. Both victims survived. To eliminate the only eyewitness, Simard murdered Jean-Marc Caissy on March 28, 1997, shooting him five times in the face to disfigure him—part of a violent signature Simard later admitted to preferring. He alerted his superior via pager immediately after the killing. That same month, he hid the murder weapon in a locker at a local gym, where it was eventually found by a janitor and traced through ballistics to Caissy’s murder.

Simard was arrested on April 11, 1997, when he returned to the gym to retrieve the gun. Upon arrest, he agreed to cooperate with the police. He confessed to multiple murders, including the killing of MacFarlane and Caissy, and identified high-ranking Hells Angels and Rockers leaders who gave the orders. He also exposed Kane's double life as both a contract killer and a police informant, causing significant disruption between police agencies.

Simard became a crown witness, and in exchange for his testimony, he received a reduced sentence of life imprisonment with the possibility of parole after 12 years. However, his courtroom performance was criticized—judges described him as cold, remorseless, and manipulative. He failed to secure convictions in some major trials, including the acquittal of Rockers president Gregory Woolley.

Despite cooperating with authorities, Simard was not given a new identity as promised. He feared retribution from the Hells Angels and requested a prison transfer to Saskatchewan, believing it would be safer than British Columbia. While imprisoned at the Prince Albert Institution, he warned prison officials that he felt hunted.

On July 18, 2003, Simard was found dead in his cell—stabbed 187 times with a sharpened metal rod. Blood led investigators to the cell of Alvin Starblanket. Testimony later revealed that Starblanket had accepted a $25,000 contract to kill Simard, with fellow inmate Christopher Cluney also involved. Simard’s brutal death occurred just as he was preparing to testify in another case against organized crime.

Starblanket pleaded guilty to second-degree murder and was sentenced to life imprisonment without parole for 13 years. Cluney, tried separately, also received a second-degree murder conviction.
