OTTAWA / RIGA Gunner Sebastian Halmagean, 27, of Hamilton, Ontario, died near Riga, Latvia, on Thursday, January 29. He was on his first overseas deployment. The Department of National Defence confirmed his death in a press release issued Friday evening.
Halmagean was posted to the 4th Artillery Regiment (General Support), Royal Canadian Artillery, based at 5th Canadian Division Support Base Gagetown in Oromocto, New Brunswick. He was deployed as part of the Air Defence Battery within the Multinational Artillery Battalion Group at NATO Multinational Brigade Latvia — Canada’s contribution to NATO’s enhanced forward presence on the alliance’s eastern flank.
He had served in the Canadian Armed Forces for nearly three years.
What Is Known
The cause of death has not been disclosed. DND stated that the circumstances are under investigation and that “no further information will be provided.”
Canadian Joint Operations Command Public Affairs told CTV News that Halmagean was on duty at the time of his death. That detail does not appear in DND’s official press release.
The investigation is being conducted by the Canadian Forces Military Police with support from the Latvian State Police, according to DND’s press release. However, multiple Canadian Press reports — including those carried by the Globe and Mail and several other outlets — describe it as being led by the Latvian Military Police with support from the Canadian Forces Military Police. The two accounts reverse who is leading and who is supporting. Neither DND nor Canadian Joint Operations Command has publicly clarified which account is accurate.
Who He Was
Halmagean was originally from Hamilton, Ontario. A social media post from a man identifying himself as Halmagean’s father included photos of the soldier and noted that he had helped fight wildfires in Newfoundland and Labrador in 2024. The post described him as “immensely proud to serve in the Canadian Armed Forces and his country” and asked for privacy.
Chief of the Defence Staff General Jennie Carignan said in DND’s release: “Gunner Halmagean was at the beginning of a promising career, and we will remember his dedication and commitment to service.”
Lieutenant-General Steve Boivin, Commander of Canadian Joint Operations Command, said: “Gunner Halmagean deployed on Operation Reassurance with a sense of duty to serve his country.”
Prime Minister Mark Carney issued a statement on social media expressing condolences to the family.
Context: The Third Death in 15 Months
Halmagean is the third Canadian Armed Forces member to die during Operation Reassurance in Latvia since October 2024.
Captain Aaron Wideman died off-duty in Riga on October 13, 2024. The cause of death has not been publicly disclosed. The investigation was reported as concluded in January 2026; no findings have been made public.
Warrant Officer George Hohl was reported missing on September 2, 2025, and found deceased on September 5. DND did not disclose the cause of death. In January 2026, Hohl’s widow, Michelle, publicly stated that he had died by suicide.
Three deaths across a deployment of roughly 2,000 personnel in just over a year. Operation Reassurance was renewed by Prime Minister Carney in August 2025 for another three years, through 2029.

What DND Has Not Said
DND has not disclosed the cause of Halmagean’s death, the specific location within the Riga area, or the circumstances surrounding it. The department has not provided a timeline for when investigation findings will be released, or whether they will be made public at all.
When asked by reporters for further details, the Canadian Armed Forces responded that additional information would not be provided in order to protect the integrity of the ongoing investigation.
