Riverdale Branch, Toronto Public Library 1910
Designed in Georgian Revival style by city architect Robert McCallum, Riverdale Branch was one of ten public libraries built with Carnegie grants in what is now Toronto. The wedge-shaped building was erected on part of the Don Jail Governor's garden, and replaced an earlier branch, Eastern (1888), located on Boulton Avenue near Queen Street East. Constructed of red brick with Ohio sandstone finishing, Riverdale library features a distinctive upper balustrade, a retaining wall in matching materials, and, rare for a Carnegie library, a corner entrance. Riverdale was one of the first Toronto branches to provide children's services, for which a Boys and Girls Library wing, designed by W.S. Butler, Architect, was added in 1927. Surviving a fire in 1969, this important community landmark has since been further enlarged twice.
