Mario Bachand was a member of the Front de Liberation du Quebec, imprisoned for his role in planting bombs in Montreal.
After his release, Bachand remained politically active in Montreal, founding several activist, leftist movements.
He was close friends with Jacques Lanctôt, who in 1970 would lead the Liberation Cell in the kidnapping of British diplomat James Cross, the event that initiated the October Crisis.
In April 1969 Bachand fled to Havana, where he met up with other FLQ who had sought refuge in Cuba, including Pierre Charette, Alain Allard and Raymond Villeneuve.
He was found shot to death in the apartment of Pierre Barral and his wife, Françoise, in the Paris suburb of St. Ouen on March 29, 1971, following a cous cous lunch with them and Norman Roy and Denyse Leduc of the DEFLQ (Delegation extérierure du FLQ).
