In recent years, Canada has witnessed a series of significant data breaches that have compromised the personal information of millions. These incidents highlight the urgent need for robust data protection measures and a thorough understanding of the evolving cybersecurity landscape. Below, we delve into five notable data breaches and offer guidance on safeguarding your personal information.

1. Ticketmaster Data Breach
In July 2024, Ticketmaster, a subsidiary of Live Nation Entertainment, experienced a substantial data breach affecting millions globally, including a significant number of Canadians. The breach exposed personal details such as names, email addresses, and payment information. The Privacy Commissioner of Canada, Philippe Dufresne, promptly initiated an investigation to determine the breach’s cause and to implement measures to prevent future occurrences.
2. Canada Revenue Agency (CRA) Cyberattacks
Since 2020, the Canada Revenue Agency has been the target of multiple cyberattacks, leading to over 30,000 privacy breaches. These breaches compromised sensitive taxpayer information, including Social Insurance Numbers and financial data. In May 2024, the CRA reported these incidents to the Office of the Privacy Commissioner, prompting an investigation into whether the agency met its obligations under the federal Privacy Act.
3. AT&T Data Breach Linked to Canadian Hacker
In November 2024, Canadian authorities arrested Alexander “Connor” Moucka, suspected of leading a group responsible for significant data breaches targeting companies like AT&T. Operating under aliases such as “Waifu” and “Judische,” Moucka allegedly stole extensive customer data, including phone records and geolocation information. Investigations revealed that compromised login credentials, often obtained through malware, facilitated these breaches.
4. Canada Border Services Agency (CBSA) Data Breach
The CBSA reported a data breach affecting approximately 18,000 employees, attributed to an internal error. An employee inadvertently sent sensitive information, including names and contact details, to an unauthorized recipient. This incident underscores the importance of stringent internal data handling protocols and employee training to prevent such occurrences.
5. TikTok’s Operations Halted in Canada Over Security Concerns
In a decisive move, Canada ordered ByteDance, the Chinese owner of TikTok, to cease its operations within the country due to national security concerns. Analyses indicated that TikTok collected extensive personal information, including data about Wi-Fi networks and SIM cards, raising significant privacy issues. This action reflects Canada’s proactive stance in addressing potential threats to citizens’ data privacy.
Protecting Your Personal Information
In light of these breaches, it’s crucial to take proactive steps to safeguard your personal data:
- Regularly Monitor Accounts: Frequently check your financial and online accounts for any unauthorized activities.
- Use Strong, Unique Passwords: Employ complex passwords and consider using a reputable password manager to keep track of them.
- Enable Two-Factor Authentication (2FA): Adding an extra layer of security can prevent unauthorized access even if your password is compromised.
- Stay Informed: Keep abreast of the latest news regarding data breaches and cybersecurity threats to remain vigilant.
- Be Cautious with Personal Information: Share personal data only when necessary and ensure you’re interacting with trusted entities.
