Cybersecurity Threats Facing Canadian Aviation Companies – 2026 Report
Section | Key Findings | Source |
|---|---|---|
Industry‑wide context | Canada’s aviation sector is increasingly viewed as a high‑value target due to its critical infrastructure status and the digital transformation of operations (e.g., advanced avionics, cloud‑based training). | [1] |
Recent major incidents | • WestJet Airlines suffered a cyber incident that disrupted its app and website operations, prompting a company‑wide investigation into the extent of the breach. | [1] |
Academic & industry collaboration | • A collaboration between McGill University, Queen’s University, the Royal Military College of Canada, and CAE (an aviation training and simulation technology firm) was announced to targetedly research and mitigate cyber risks in aerospace systems. This partnership aims to develop both defensive strategies and threat‑intelligence capabilities tailored for the aviation domain. | [1] |
National threat landscape | • The Canadian Centre for Cyber Security publishes an annual “National Cyber Threat Assessment” that highlights a rising number of attacks on critical infrastructure, with aviation systems noted as especially sensitive due to their connectivity and regulatory oversight. | [1] |
Common vulnerability vectors | 1. Third‑party supply chain – training simulations and airline software often rely on external vendors. | [1] |
Regulatory & framework guidance | • Canadian aviation authorities (e.g., Transport Canada) and international bodies (ICAO) recommend adopting a comprehensive cyber‑security framework such as NIST CSF or the ICAO Cyber‑Security Security Guidance. Airlines are advised to undertake continuous risk assessment, staff training, and incident response planning. | [1] |
Strategic recommendations | 1. Implement zero‑trust network segmentation across both operational technology (OT) and information technology (IT) layers. | [1] |
Cybersecurity Threats to Canadian Aviation Companies: Report
1. Regulatory Context and Oversight
Transport Canada serves as the primary authority responsible for aviation security in Canada. The department manages the civil Aviation Security Program using a set of policies and regulations designed to protect air travel and trade. The program's goals focus on teaching stakeholders security requirements, promoting a strong security culture, and encouraging proactive security behaviors [3].
2. Recent Cyber Incidents
Several significant cyber incidents have impacted the aviation sector, highlighting the evolving threat landscape:
Toronto Pearson Airport (2022): In 2022, the Greater Toronto Airports Authority (GTAA) experienced a ransomware attack that disrupted internal IT systems, including portions of the website and administrative networks. While critical aviation safety and air traffic control systems remained uncompromised, the incident caused temporary service interruptions. This event demonstrated the importance of cyber resilience, where non-operational IT disruptions can create cascading logistical challenges [2].
Envoy Air Data Breach (2025): On October 21, 2025, Envoy Air, a regional carrier of American Airlines, disclosed a data breach involving sophisticated cyber-risk factors. This incident referenced specific vulnerabilities including CVE‑2025‑54539 and CVE‑2025‑61882, illustrating the potential for targeted attacks on airline networks [1].
LockBit Group Targeting: There have been attempts on major infrastructure entities, such as a ransomware attempt against Boeing by the LockBit Group in 2023 [2].
3. Critical Infrastructure Vulnerabilities
Cyber threats often extend beyond traditional IT networks to industrial control systems (ICS) and commercial products. Current advisories highlight vulnerabilities in a range of industrial and security products affecting various entities.
Affected Products: Vulnerabilities have been identified in systems such as Aviation Light Engine Pro, Hitachi Energy FOX61x, Mitsubishi Electric MELSEC iQ‑R, and TP‑Link Systems VIGI Series IP Cameras [1].
Vulnerabilities: Specific CVEs have been associated with ongoing campaigns targeting critical infrastructure, such as the Cisco IOS XE devices exploited via CVE‑2023‑20198 by the Australian Signals Directorate [1].
Actionable Intelligence: Administrators are urged to review advisories from sources like the Cybersecurity and Infrastructure Security Agency (CISA) to implement mitigations and apply available updates for products like GE Vernova Enervista UR Setup and Siemens Simcenter Femap [1].
4. Impact and Resilience
The impact of cyber incidents varies depending on the nature of the disruption. In the case of the Toronto Pearson attack, flight operations continued uninterrupted, but administrative services faced disruption. The attack prompted significant investment in cybersecurity modernization, reinforcing segmentation, monitoring, and incident response capabilities [2].
5. Recommendations for Mitigation
To safeguard critical infrastructure against evolving ransomware and cyber-attack threats, stakeholders should take the following actions [1] [2]:
Segmentation: Strengthen network segmentation to isolate critical operational technology (OT) from administrative networks.
Monitoring: Enhance continuous monitoring capabilities to detect ransomware and anomalous activity early.
Updates: Regularly review advisories and install patches for affected products and firmware versions.
Incident Response: Ensure robust incident response plans are in place to minimize passenger and operational impact during containment efforts [2].
Conclusion
The aviation sector in Canada faces evolving threats ranging from ransomware targeting high-visibility infrastructure to specific vulnerabilities in industrial control systems. While organizations like Toronto Pearson have demonstrated resilience, continuous investment in modernization and adherence to Transport Canada’s security guidelines are essential to maintain air travel safety and operational integrity [3] [2].
Bottom line:
Canadian aviation companies are facing a multi‑faceted cyber threat environment characterized by high‑profile incidents such as WestJet’s recent breach, escalating ransomware and credential‑based attacks, and systemic vulnerabilities stemming from legacy controls and complex supply‑chain relationships. Effective mitigation requires coordinated industry‑wide research (e.g., the McGill partnership), adherence to internationally recognised frameworks (NIST, ICAO), and proactive resilience investments across IT/OT boundaries.
