FALLOON, John (1858 - c. 1887) of Toronto, Ont. was active as an architect, at first under his own name, and later as a member of two different architectural partnerships. He was the son-in-law of Richard C. Windeyer, and may have been brought to Toronto by the Windeyer family. Born in Melbourne Township, Quebec, near Sherbrooke, he was the son of an Irish church minister Rev. Daniel Falloon, and he arrived in Toronto in 1877. In September 1877 he was one of 34 architects who submitted a design in the competition for the new High School at Stratford, Ont. (Stratford Beacon, 5 Oct. 1877, 2, list of entrants). His entry was passed over in favour of the winning design by McCaw & Lennox of Toronto.
In May 1878 he was invited by Arthur R. Denison to form a partnership (see list works under Denison & Falloon). This was dissolved in February 1879, and Falloon worked alone until April 1887. In June 1887, at the age of 29 years, he was invited to form another partnership, this time with R.C. Windeyer (see entry under Windeyer & Falloon), but their collaboration ended within three months, and Falloon was again working alone. No references to his work after this date have been found (biog. in M.G. Bixby, Industries of Canada - Toronto, 1886, 106).
