He was one of seven children born to William Massey Birks and Miriam. His father was a partner in the jewelers Henry Birks & Sons with his father and brothers. The Birks were descended from a farming family from Darfield, Yorkshire, who emigrated to Canada in 1832. Birks was educated at Montreal High School and Lower Canada College, and was studying architecture at McGill University when the war broke out.
World War I
Birks enlisted in the Canadian Expeditionary Force on 31 August 1915, serving as a lieutenant in the 73rd Battalion, and was wounded in November 1916 during the Battle of the Somme. Birks joined RFC Canada on 8 March 1917, and trained as a pilot at Deseronto and Camp Borden. He flew solo after only 2 hours of flight training, and was commissioned as a second lieutenant in the RFC on 13 August 1917, but did not travel out to England until November. He was posted to No. 54 Training Squadron in December, was appointed a flying officer on 15 January 1918, and posted to the No. 2 School of Aerial Gunnery in February. This extended training period meant that he had accumulated 138 flying hours in his pilot's logbook before he finally joined No. 66 Squadron RFC in Italy on 10 March 1918. He was assigned to "C" Flight, flying a Sopwith Camelsingle seat fighter, and became the preferred wingman of fellow Canadian ace Billy Barker. Birks' first aerial victory came on 18 March, when he destroyed a Rumpler reconnaissance aircraft over Pravisdomini, killing an Austro-Hungarian pilot named Shneeberger. Six days later, he set another reconnaissance aircraft on fire, killing the crew of Poelzi and Suski. His third victory would not come until 2 May, when he wounded Leutnant K. Kosiuski and drove him into a crash landing that destroyed his Albatros D.V. Two days later, Birks shot down and killed ace OberleutnantKarl Patzelt, as well as F. Frisch. In addition to killing both Austro-Hungarian pilots, he destroyed both their Albatros D.Vs; they were credited as "captured" because they fell within Italian lines. The new ace shot down another D.V in flames a week later, on 11 May. He destroyed two Berg fighters in five minutes on a morning patrol on 19 May. The following day, he destroyed another. On 24 May, while flying with Barker, Birks was credited with shooting down Hungarian ace József Kiss of Flik 55J; Birks thus became a double ace. On 9 June Birks set another Albatros D.V on fire in mid-air. On the 21st, he capped his list of triumphs by destroying another D.V over Motta. Most unusually for a British pilot, he had no "soft" victories, such as "driven down out of control". Birks left No. 66 Squadron on 1 July 1918, returning to the Home Establishment to serve as an instructor at the School of Aerial Fighting and Gunnery from September. He was awarded the Military Cross and a bar in lieu of a second award; both were gazetted on 16 September 1918. His citations read: ;Military Cross ;Bar to Military Cross Birks was transferred to the RAF's unemployed list on 13 March 1919.
After the war, Birks rejoined the family jewelry business, and on 21 August 1924, he married Margaret Ryrie of Toronto. Birks became a patron of the arts, and was an active painter until his death in Toronto on 26 May 1991.
