In Southern Ontario there are two types of Italian organized crime Cosa Nostra (Sicilian) and 'Ndrangheta (Calabrian). In the 2018 book, The Good Mothers: The True Story of the Women Who Took on the World's Most Powerful Mafia, Alex Perry reports that the Calabrian 'Ndrangheta has, for the past decade, been replacing the Sicilian Cosa Nostra as the primary drug traffickers in North America.

- Siderno Group – is the name for the "'Ndrangheta" clans (crime families). There have been seven senior 'Ndrangheta bosses in the Greater Toronto Area, some on the Camera di Controllo, the "board of directors" – namely in Vaughan. The Toronto-area Siderno group has included the Coluccio, Tavernese, DeMaria, Figliomeni, Ruso, and Commisso crime families; Carmine Verduci was also linked with the 'Ndrangheta group. Leaders are based both in Calabria and Ontario. The Siderno clans are part of the Commisso 'ndrina a crime family based in Calabria, Italy.
During a 2018 criminal trial, an Italian police expert testified that the 'Ndrangheta operated in the Greater Toronto Area and in Thunder Bay particularly in drug trafficking, extortion, loan sharking, theft of public funds, robbery, fraud, electoral crimes and crimes of violence. After the trial, Tom Andreopoulos, deputy chief federal prosecutor, said that this was the first time in Canada that the 'Ndrangheta was targeted as an organized crime group since 1997, when the Criminal Code was amended to include the offence of criminal organization. He offered this comment about the organization:
"We’re talking about structured organized crime. We’re talking about a political entity, almost; a culture of crime that colonizes across the sea from Italy to Canada. This is one of the most sophisticated criminal organizations in the world."
In Quebec there are two types of Italian organized crime: Cosa Nostra and 'Ndrangheta. While Canadian law enforcement agencies consider the Rizzuto and Cotroni crime families to be separate, the FBI considers them to be sub-units of the Bonanno crime family's Montreal faction.
