Ad Astra Boulevard was dedicated by the Canada Lands Company on May 22, 2012, as part of their redevelopment of Edmonton’s former Canadian Forces Base (Griesbach Barracks).

April 1, 1924, has been celebrated as the birthday of the Royal Canadian Air Force. The new Royal Canadian Air Force adopted the Royal Air Force’s motto Per Ardua Ad Astra – Through adversity to the stars – which replaced the Canadian Air Force’s original motto Sic Itur Ad Astra – Such is the pathway (or “This is the way”) to the stars.
