The West End Gang is one of Canada's most influential criminal groups. Active since the early 1900s, their rise to notoriety began in the 1960s, when they were known simply as the "Irish gang" and their criminal activites were focused in the west side of Montreal. Most of the gang's earnings derived from truck hijacking, home invasions, kidnapping, and armed robbery.

The Irish-dominated mob, but not exclusively comprised of members of Irish extraction, expanded its rackets in the 1970's to include drugs. They began to import large quantities of hashish and cocaine and developed important contacts in the United States, South America, and Europe. Members also worked out of Florida.

The gang formulated ties to the Montreal Mafia cosa nostra and Hells Angels. Three organizations make up the "Consortium" (similar to New York City's "Commission").

Most of the drugs are smuggled into the United States, the world's largest drug market, and the rest is sold throughout Quebec and other provinces.
