Espionage Case Raises Concerns Over Canada's Intelligence Sharing with Allies

In late July, a Canadian woman of Chinese descent was arrested in Belgium on serious espionage charges for China while serving as an intern with NATO. Identified as Biwei Zhang, also known as Claire Zhang or Catina Zhang, she was born in China and later became a naturalized Canadian citizen. Zhang has a background in systems engineering, computer science, and economics. She began her internship at NATO’s Supreme Headquarters Allied Powers Europe (SHAPE) in Mons, Belgium, in July 2025, after previous roles at the Canadian Space Agency and Statistics Canada.

Zhang worked in the IT department at SHAPE, which serves as the central operational command hub for NATO's 32 member nations. Her behavior raised suspicions, including excessive curiosity about her colleagues and unauthorized access to restricted areas. These actions led SHAPE security to flag her for further investigation, which was referred to Belgian intelligence.

Following a search of her home and workplace, Zhang was placed in pretrial detention, which has since been extended. NATO has stated that no sensitive information was compromised. Zhang has not publicly commented on the allegations but has appealed her detention order, with a decision expected soon.

This incident is indicative of broader security concerns regarding Canada’s relationship with China. Canada is part of the Five Eyes intelligence alliance, which includes Australia, New Zealand, the United Kingdom, and the United States, and shares critical intelligence on foreign threats, including espionage. The case raises questions about Canada’s ability to protect sensitive information, especially as it continues to strengthen economic ties with Beijing despite ongoing security concerns.

Reports have surfaced about Zhang's troubling history, including a 2019 incident where she submitted two applications for a position at the Canada Border Services Agency under different names, allowing her to take the eligibility exam twice in one day. This deception was confirmed by a 2023 investigation and upheld by a federal court in 2024, resulting in a requirement for her to complete an ethics course before accepting certain public service roles.

Despite this history, Zhang was granted security clearance for her NATO internship after assessments by the Canadian Security Intelligence Service and checks by the Royal Canadian Mounted Police. This raises alarming questions about the adequacy of Canada’s security screening processes for sensitive positions.

In light of these events, Public Safety Minister Gary Anandasangaree has promised a review of security protocols to address these lapses. However, the effectiveness of such a review remains uncertain.

A draft report from the National Security and Intelligence Committee of Parliamentarians revealed that Canadian leaders often prioritize trade and political objectives over security concerns. This pattern has led to warnings from Canada’s spy agency about foreign interference, particularly from China, being downplayed.

Since taking office, Prime Minister Carney has sought closer ties with China, culminating in a January 2026 visit to Beijing, where he and Chinese leader Xi Jinping announced a new strategic partnership. This partnership includes limited imports of Chinese electric vehicles, despite U.S. warnings about associated security risks. Following this announcement, U.S. Ambassador to Canada Pete Hoekstra stated that these vehicles would not be allowed to cross the U.S. border.

Zhang’s case serves as a stark reminder that until Canada can demonstrate a commitment to rigorous security screening and prioritize national security over short-term commercial interests, its allies, particularly the United States, may need to reconsider the extent of intelligence sharing with Ottawa.
