Canadian service member faces court-martial for sharing sensitive information with Ukraine

A Canadian military counter-intelligence agent accused of passing sensitive operational information to Ukraine is due to face a court-martial in December 2026. The case matters because it involves alleged breaches of national security and military trust by a member of Canada’s intelligence command, even as Canada remains a major supporter of Ukraine.

Master Warrant Officer Matthew Robar is charged with violating foreign interference laws and military responsibilities in late 2025; the court-martial is scheduled for 9 December. The information he allegedly shared has not been specified, though CBC reported he communicated with Ukrainian contacts and met a Ukrainian representative in Lithuania in 2024. He also faces charges of lying to superiors and improperly storing a firearm. Canada recently announced an initial €500 million contribution to the EU’s Ukraine Support Loan.
