Don Mahar
Don Mahar dedicated over four decades to Canada's national security and intelligence community, serving with distinction in the Royal Canadian Mounted Police (RCMP), RCMP Security Service, the Canadian Security Intelligence Service (CSIS), and the Communications Security Establishment (CSE).
Throughout his career with the RCMP Security Service and CSIS, Mr. Mahar specialized in Counter Intelligence, with a strong focus on the intelligence operations of Soviet, Chinese, and Iranian services. His expertise in this field placed him at the forefront of Canada’s efforts to detect and counter foreign espionage during and after the Cold War.
In 1987, he undertook a temporary posting to Hong Kong, expanding his international operational experience. From 1997 to 2000, Mr. Mahar was posted to East Africa, where he had the distinction of opening the first CSIS Station in the region, overseeing intelligence responsibilities across 13 countries.
Upon his return to Canada, he transitioned to Counter Terrorism operations from 2000 to 2004, a period during which he travelled frequently to the Middle East in support of national security missions. He retired from CSIS in 2004 and continued his service to Canada at the Communications Security Establishment, where he worked until 2010.
In 2017, Mr. Mahar authored the book Shattered Illusions: KGB Cold War Espionage in Canada, a work that was formally authorized by CSIS. The book offers an insider’s perspective on Soviet espionage activities in Canada and reflects his deep knowledge of Cold War intelligence operations.
