The North Toronto wing was the third flying station of the brigade to go into action. It was subdivided into two units, Leaside and Armour Heights, the ground for the former being most generously offered free of charge by the York Land Company and the town of Leaside; while for the use of the latter area the Corps is indebted to F. B. Robins, Esq.

Actual construction commenced on May 21st. Leaside, comprising 222 acres, presented an admirable surface which was carefully drained. The structural programme called for nine flight sheds, together with instructional and repair buildings, etc. At the close of hostilities there was accommodation for 89 officers, 230 cadets, 83 warrant officers and sergeants, and about 600 rank and file, the latter being housed in a large factory building, the use of which was secured from the Leaside Munitions Company. In the autumn of 1918, work was commenced on a central heating plant serving the officers’ and cadets’ quarters.

The territory north, east and west of Leaside presented a country with fairly large fields and but little wooded land, and there was in consequence every opportunity for forced landings. As this station was the main point at which training was given in artillery coÖperation, a most complete system of observation huts connected by telephones, was constructed and dotted the countryside for miles around.

Leaside has always been a point of interest to visitors on account of its proximity to Toronto, and has had the honor of inspection by H.R.H. Prince Arthur of Connaught and the Duke of Devonshire, at that time Governor-General of Canada. From Leaside also started the aerial mail which, under the auspices of the Aero Club of Canada, made several trips to Montreal and Ottawa, and demonstrated the great advantage that will no doubt accrue from the use of aerial transport for this purpose.

At Armour Heights were the squadrons detailed to give instruction in what is known as the Armour Heights course. The aerodrome lies some five miles north of Toronto. Here accommodation was provided for 58 officers, 56 cadets, 32 warrant officers and sergeants and 188 rank and file. The type of building and general arrangement of the station did not present any features varying noticeably from other camps, but this unit was always the object of much interest to visitors on account of the advanced flying at all times observable. The output of instructors here graduated has been vital to the success of the Corps, and the keenness and enthusiasm displayed was undoubtedly fostered by the brilliant example set by the flight commander who for many months was in charge. His record has been worthily maintained.
