Richard Heath Rohmer OC CMM OOnt DFC CD KC (born January 24, 1924) is a Canadian aviator, lawyer, adviser, author and historian.

The Peterborough Examiner's lead editorial of January 14, 2009 describes Rohmer as "one of Canada's most colourful figures of the past half-century".

General Rohmer served as honorary advisor to the Chief of the Defence Staff of the Canadian Armed Forces from 2014 to 2017.

After his studies in high school he worked briefly at Fleet Aerospace before joining in 1942 on his 18th birthday the Royal Canadian Air Force (RCAF).

In Europe in 1943–44 as a reconnaissance pilot flying North American Mustang fighters he completed a 135-mission tour of operations at the end of November 1944 in Holland.

[1] Rohmer reported the car's location to Group Control Centre, which sent in a Spitfire piloted by Canadian Charley Fox.

He served at HMCS Hunter in Windsor, Ontario, as commanding officer University Naval Training Division (UNTD) from 1946 until he retired in 1948.

On December 22, 2014, Major-General (Retired) Rohmer was named honorary advisor to the Canadian Armed Forces Chief of the Defence Staff, a three-year appointment "...created to recognize MGen (Ret’d) Rohmer’s contributions to the Canadian Armed Forces, and the unique advice and guidance that he provides to the Chief of the Defence Staff, drawing from his wealth of experience in service to Canada".

[4] In the late 1960s and early 1970s, Rohmer promoted a plan for a megaproject to develop and populate the Canadian sub-Arctic which he called the "Mid-Canada Corridor".

His major official plan change success occurred in 1972 when as counsel for Canadian National Railway and Canadian Pacific Railway and their subsidiaries he appeared before the Ontario Municipal Board in a six-week contested hearing that resulted in the change of the official plan for all of the railway use lands around Union Station from Yonge Street to Bathurst Street (185 acres) to a high density mix of residential, commercial, entertainment, hotels, sport centres and other uses including construction of the CN Tower.

Ultimatum, published in 1973, features political, economic, and energy crisis themes as well as the author's opinion about the viability of the Canadian nation.

[13] He was chairman of the 60th anniversary of D-Day celebrations that took place in the presence of the Queen of Canada at Juno Beach in Normandy on 6 June 2004.

Rohmer turned 100 on January 24, 2024[16] and resides in the veterans’ wing of Sunnybrook Health Sciences Centre in Toronto.
