Canada's First Aerodrome
In May, 1915, Curtiss Aeroplanes and Motors, Ltd. established Canada's first aerodrome and flying school on this site. The school, and the Curtiss aircraft factory on Strachan Avenue in Toronto were managed by John A.D. McCurdy, Canada's first aviator. Most of the graduates went to England at their own expense, to join the Royal Flying Corps or the Royal Naval Air Service. When the Royal Flying Corps, Canada, was created in January, 1917, its first flying units were based at Long Branch. Later that year, when Armour Heights and Leaside were prepared for flying, Long Branch became the ground training school for the cadet wing of the R.F.C.
