The House of Commons public safety committee heard on Wednesday that Global Affairs Canada did not routinely examine social‑media profiles when granting “secret” level clearance to individuals such as Biwei Zhang, the Canadian intern arrested by Belgian police in July on suspicion of espionage. The department relied on vetting by the Canadian Security Intelligence Service and criminal record checks conducted by the RCMP, but officials confirmed that internet searches were not required for clearance at that tier.
Vetting Procedures Under Scrutiny
Tara Denham, assistant deputy minister at Global Affairs, told MPs that the absence of online checks was standard practice for “secret” clearance, unlike the more stringent process for “top secret” appointments. She noted that, following Zhang’s arrest, the department has begun proactively reviewing applicants’ internet presence as part of its security programme.
Official Testimony on Online Checks
Brigadier‑General Liam Cox, director general of defence security at the Department of National Defence, warned that a surface‑level scan of social media would unlikely catch a sophisticated spy. “If somebody has any statecraft, they can obfuscate their behaviour, and we wouldn’t find it with a surface‑level internet check,” he said. He stressed that reliance on any single tool is insufficient and that layered defences remain essential.
Broader Insider Threat Concerns
Denham highlighted that espionage and the targeting of government staff are persistent challenges faced by Canada and its NATO allies. She added that cyber threats, impersonation of officials overseas and online harassment also feature among the risks that demand continual vigilance. Public Safety Minister Gary Anandasangaree indicated that Zhang’s prior federal postings – including stints at the Canadian Space Agency, Statistics Canada and Employment and Social Development Canada – will be examined once Belgium’s investigation concludes.
Why it Matters
The case underscores a tangible gap in Canada’s personnel security framework: the reliance on traditional checks without systematic online scrutiny may allow individuals with concealed intentions to access sensitive environments. As allied nations confront increasingly sophisticated insider threats, the incident pushes Canadian agencies to modernise vetting procedures, ensuring that digital footprints are examined alongside classic background investigations to protect national security and maintain trust with NATO partners.
