Victor Avenue, 1886, was named for Victor Thomas, a sporting man of the area. One might speculate that the sport was horse racing, very popular in the 19th century York-Toronto, which was horse dependent for transport and where there were many retired army officers. A number of private stables remain in Riverdale. In 1886 Victor was not built on.
The residence at 20 Victor was the home of Thomas Foster, mayor of Toronto, 1925-1927.
52-54 Victor is probably the tallest residence in Riverdale. 54 was once the home of Elgin Schoff of the law firm of Schoff and Eastwood.
