The Canadian Investment Regulatory Organization (CIRO) disclosed that hackers stole personal data from 750,000 individuals during a sophisticated phishing attack in August 2025. The compromised information includes social insurance numbers, dates of birth, government ID numbers, income details, and investment account information.

CIRO says the breach didn't affect critical operations and there's no evidence the stolen data has been misused or appeared on the dark web. The organization is providing two years of free credit monitoring to affected individuals and has started mailing notification letters to impacted clients.
