Clifford Mackay McEwen

“Some men fly aircraft. A rare few help build a nation’s air power.” That was Clifford Mackay McEwen’s legacy—a combat pilot, decorated war leader, and one of the architects of modern Canadian military aviation. Clifford Mackay McEwen

Born in 1896 in Grey County, McEwen first proved himself during the First World War, serving with distinction in the artillery before transferring to aviation. In the skies over Europe, he demonstrated exceptional courage and leadership, earning the Distinguished Service Order (DSO), Military Cross (MC), and Distinguished Flying Cross with Bar (DFC & Bar)—a remarkable collection of gallantry awards reflecting repeated acts of bravery under fire. His service in the Great War marked him as one of Canada’s outstanding airmen.

But McEwen’s greatest contribution came not in a cockpit, but in command. During the Second World War, he rose through the ranks of the Royal Canadian Air Force and became a central figure in expanding Canada’s air capabilities during one of history’s most dangerous conflicts. He played a crucial role in training, organization, and operational leadership as the RCAF transformed into a formidable Allied air force. His strategic influence helped ensure Canadian air power became a decisive part of the Allied war effort.

His wartime leadership earned him appointment as a Commander of the Order of the British Empire (CBE) and later Companion of the Order of the Bath (CB)—prestigious honours reserved for those whose service extended far beyond battlefield heroics. These awards recognized not only personal courage, but also the rare ability to shape military institutions at the highest level.

Clifford McEwen’s story is compelling because it bridges two eras of warfare: the fragile biplanes of the First World War and the industrial air power of the Second. Few officers successfully navigated both worlds; fewer still left such a lasting impact on Canadian military history.

When McEwen died in 1967, he left behind more than medals and decorations. He left a legacy of leadership, innovation, and service that helped define Canadian aviation. From frontline pilot to senior commander, Clifford Mackay McEwen remains one of the most important figures in the history of the Royal Canadian Air Force.
