On Tuesday, May 4, 2026, Diana Toro Díaz, a financial operator for the Sinaloa Cartel sanctioned by the United States under the Kingpin Act, was arrested at Montreal-Trudeau Airport after attempting to enter Canada with a false passport more than a week prior.
According to the Canadian news outlet TVA Nouvelles, Toro Díaz is being held at the Immigration Detention Center awaiting a decision from the Immigration and Refugee Board regarding her future, although she could be extradited to the United States to face charges.
The Sinaloa Cartel’s financial operator, who holds both Colombian and Mexican citizenship, had entered Canada several times in recent years using false documents, the outlet reported.
Toro Díaz, 44, was sanctioned by the U.S. Treasury Department in 2010 for her involvement in the financial network of her husband, Alejandro Flores Cacho, a pilot who controls a multinational drug trafficking network.
Flores Cacho managed the airlines used by Joaquín Guzmán Loera, alias “El Chapo,” and Ismael Zambada, alias “El Mayo,” for drug trafficking prior to their arrests in 2016 and 2024, respectively.
The United States also sanctioned the companies Mantenimiento, Aeronáutica, Transporte y Servicios Aéreos SA de CV; Capacitación Aeronáutica Profesional SC, a flight school in Cuernavaca used to train pilots involved in drug trafficking; and Aero Express Intercontinental SA de CV, an air cargo company based in Mexico City.
According to OFAC documents, Toro Díaz and Javier Flores Cacho, the pilot’s brother, operated front companies such as a restaurant, a cattle ranch, an agricultural company, a manufacturing and distribution company, a sports management club, and an office supply store.
The network operated in Baja California, Mexico City, Cuernavaca, the State of Mexico, and Colombia.
