The Long Branch Aerodrome has the distinction of being the first Aerodrome in Canada and home to Canada's first aviator training school. It opened on May 20, 1915, by Curtiss Aeroplanes and Motors Company for the Royal Flying Corps. Aircraft such as the Curtiss JN-4 "Jenny" soon became a common sight at the airfield, which included three aircraft hangars. In January 1917, the newly designated Royal Flying Corps, Canada, the forerunner to the Royal Canadian Air Force, opened the RFC Training Centre at Long Branch. The Long Branch training centre also provided instruction on flying boats at nearby Hanlan's Point on Toronto Islands, the first seaplane base in Canada. By July 1917, the flight school re-located to the Armour Heights Aerodrome. Long Branch became the Cadet Ground Training School for the Royal Flying Corps. Both the school and the aerodrome closed in 1919. During World War II, the former aerodrome served initially as Non-Permanent Active Militia's No 21 Training Centre and then as an army small arms training centre (Long Branch Rifle Ranges). After the war, the Lakeview Armoury was established on the site but was demolished in the 1950s. Not the slightest trace remains of the airfield today. From 1962 - 2005, the waterfront portion of the property was the location of Ontario Power Generation's Lakeview Generating Station. In September 1969, a plaque was erected at the site to commemorate Canada's first Aerodrome. Adjacent to the west side of Marie Curtis Park (now Marie Curtis Park West or Lakeshore Park) in Toronto Township is the former site of the Small Arms Limited Long Branch Arsenal. The Federal Government had owned the lands south of Lake Shore Road, between the Etobicoke River to just west of Cawthra Road, from the late 1800s into the early 20th-Century. The first land purchase was made in 1889 for a rifle range, to replace the one at New Fort York. The military use was expanded for World War I, becoming the summer quarters for several regiments and a staging area for troops to go overseas. The Ordnance Branch of the Department of National Defence authorized the construction of a factory on the site in 1940. After transfer to the Department of Munitions and Supply, a Crown Corporation, Small Arms Ltd. was formed to operate the facility. By June 1941, the first five rifles had been produced. Huge quantities of British-pattern military small arms were manufactured there during the Second World War, including the No.4 MkI* Lee–Enfield bolt-action rifle, and the Sten submachine gun (or machine-carbine).
