An investigation is underway into a “data security incident” affecting some Telus customers, according to the company. Those affected received an email this week informing them that “unauthorized individuals” were able to access information such as their name, billing address and phone number, as well as the last four digits of their payment card on file. “These individuals may have used your account information to contact you in an attempt to persuade you to move your services away from TELUS towards competitors, and/or made unauthorized changes to your TELUS services,” the email reads. Telus said the breach took place sometime “between February 2025 and June 2026,” but that the compromised credentials used have since been “terminated.” In a statement, the company’s director of public affairs told CTV News that only a small number of accounts were accessed. “We have notified affected customers, provided complimentary identity protection, and contacted law enforcement as well as the Privacy Commissioner of Canada,” said Richard Gilhooley. “We are also inviting notified customers to contact us if they are concerned about its veracity.” Affected customers have until Nov. 30 to claim the free identity protection, provided through Norton for two years, according to the email notifications sent out this week. CTV News is owned by Bell Media, which is a subsidiary of BCE Inc.
