A 66-year-old Hamilton, Ont. man is facing charges he unlawfully used military uniforms and medals when attending oath ceremonies held by Citizenship and Immigration Canada.

Hamilton Police investigators began looking into the case in December. Donald Lemmond is accused of wearing military uniforms with "various medals of questionable service."

Investigators carried out a search warrant on Friday, seizing military uniforms and medals of service "from conflicts ranging from Vietnam War to Afghanistan campaign."

Last fall, Lemmond attended local citizenship ceremonies, including one at Mohawk College, under the guise of being a decorated Canadian and U.S. combat veteran. The school then invited him to speak during its Remembrance Day ceremony, which included video commemorating Cpl. Nathan Cirillo, who was killed in an attack at the National War Memorial in Ottawa on Oct. 22, 2014.

Lemmond wore a uniform decorated with war medals and spoke of saving lives. But a member of the audience noticed that his medals were worn improperly and that his story didn’t add up, Mohawk College spokesman Jay Robb said in December.

Lemmond was released Friday under conditions he appear in court to answer to the charges, which include two charges each of unlawful use of military uniforms for both the uniform and wearing a "distinctive mark," and two charges of impersonating a peace officer using a badge, uniform or equipment.

Lemmond told CBC Hamilton in December that he served 30 years in the reserves, which he maintained makes him a veteran, and that he has classified documents to prove it.

"They're saying I'm not a veteran because I served in the reserve forces," he said.

His uniform, he said, is the uniform of Her Majesty's Army and Navy Veterans Society, which he represented at the citizenship ceremonies. An American friend sent him the medals.

Police say anyone with more information about the crime should call Const. Shannon McLean at 905-546-3817.
