Canada’s second-largest airline, WestJet, experienced a cyberattack that affected access to some internal systems and its company app. This incident restricted access for several users, prompting the airline to activate specialized internal teams. WestJet is collaborating with law enforcement and Transport Canada to investigate the matter and mitigate the impacts of the attack.
Despite the disruption to internal systems and the app, WestJet confirmed that the cyberattack did not compromise operational safety, and flight operations remain secure and unaffected. The company’s primary focus is on safeguarding sensitive personal data belonging to both guests and employees.
WestJet has advised both parties to be extra cautious when sharing personal information.
The airline published an update on June 13, 2025, acknowledging the cybersecurity incident and apologizing for any disruptions to services. As of June 14, WestJet continued to respond to the incident, working to assess the full impact and resolve the issues swiftly.
The company has not yet shared specific technical details about the nature of the attack.
This incident is part of a broader trend of increasing cyber threats targeting Canada’s critical infrastructure. Recent examples include a cyberattack on Nova Scotia Power and Emera in April 2025, and previous incidents impacting Air Canada in September 2023 and Suncor Energy in June 2023. These events highlight the ongoing need for robust cybersecurity measures across vital sectors.
