Maxime Paquette, the last fugitive in the Desjardins data breach case, was arrested in Cancun, Mexico. The breach, which occurred between 2017 and 2019, compromised personal information of nearly 10 million clients. Paquette faces multiple charges, including fraud over $5,000 and identity theft. His arrest follows a two-year manhunt involving international cooperation from agencies like Interpol and the Mexican Navy. The breach had significant implications, with reports indicating Desjardins' failure to protect customer data despite being aware of security vulnerabilities. Paquette's accomplice, Juan Pablo Serrano, was arrested in Spain in November 2025. The investigation continues as Laval police seek another suspect related to the stolen data.

Key Points: • Maxime Paquette, the last suspect in the Desjardins breach, was arrested in Mexico. • The 2019 breach affected nearly 10 million clients, with personal data sold on the Dark Web. • Desjardins was criticized for inadequate data protection measures leading to the breach.
