Rohmer was born in Hamilton, Ontario, and spent some of his early youth in Pasadena, California, as well as in western Ontario at Windsor and Fort Erie. The "Peterborough Examiner's" lead editorial of 14 January 2009 describes Rohmer as "one of Canada's most colourful figures of the past half-century". General Rohmer is the honorary advisor to the Chief of the Defence Staff of the Canadian Armed Forces. He is the advisor to the Minister of Veterans Affairs for the organization and conduct of Canada's celebration of the 70th Anniversary of D-Day celebrations in Normandy in June 2014 and the 70th Anniversary of the Liberation of Holland in May 2015. He is currently believed to be the senior surviving Canadian Veteran of D-Day, the Battle of Normandy and the Liberation of Holland.
