Dubois Gang
Gilles Leblanc
  Gilles Leblanc was one of  the Dubois Gang's  less known  members, even though he was extremely active in Montreal during  the 1970s. As a loyal soldier for the  gang's leader, Claude Dubois, Leblanc was primarily involved in strong-arming, extortion, and armed robbery.

     When Richard Désormiers began causing trouble in a club run by the Dubois Gang, Claude Dubois sent  Leblanc  and Claude Lesage  to  teach him a  lesson. The two were supposed  to give Désormiers a beating but, once on  the scene, changed  their minds. They knew that assaulting  the brother-in-law of  Frank Cotroni was  like  playing with fire. Leblanc and Lesage were later reprimanded by Dubois for not following his orders.
   Leblanc, along  with  Dubois soldiers Yvon Belzil, Réal  Lévesque, and Claude  Dubeau, provided security when Claude Dubois  met with  Frank Cotroni  numerous times  to discuss the  Désormiers problem.

     When  no resolution  could be  reached, Dubois  decided  to take  care of  business. He gave  the mission of whacking the troublesome Désormiers to Leblanc and Claude Lesage. The two enforcers were  supposed  to murder  him  and make  his body  disappear. When Leblanc and  Lesage couldn't fulfill the task a frustrated Dubois gave the contract to trusted aides Yvon Belzil and Claude Dubeau. Désormiers was murdered in the
Mon Pays bar on July 22, 1973. 

     In the  autumn of 1975, Jacques Lemieux  and Gérald Mayer opened the 
Honest John Theatrical Agency near the Agence Calcé, a booking agency for exotic dansers that was under the protection of Claude  Dubois. Dubois, who collected $250 a week from the  Agence Calcé, did  not like  the  extra competition. One evening, when  Lemieux  and  Mayer and their secretary Denise Adam were dining at  the Giusitini steak house in Saint-Léonard, Leblance and several  Dubois Gang members charged into the  restaurant and  attacked the group. Lemieux  and  Mayer were  severely beaten  and, before exiting, Leblanc fired two shots at Denise Adam, a former employee of Agence Calcé.

     Leblanc, along with Dubois soldier Michel Bernard, was shot to death in the 
l'Index nightclub on March 12, 1976. The  gang was  furious  and sought  blood. Normand  Perras, who they  suspected was one of killers, was later murdered in a tavern on Ontario street.
