One of Ontario's outstanding artists and teachers, Haines was born in Meaford and educated at this school. In 1896 he moved to Toronto where he attended the Central Ontario School of Art. He later studied at the Académic Royale des Beaux Arts in Antwerp, Belgium. Working in the realistic style as painter, etcher and printmaker, he tended to specialize in idealized Ontario pastoral landscapes. In 1928 he was appointed a curator at the Art Gallery of Toronto (Art Gallery of Ontario). As principal of the Ontario College of Art 1933-53, he introduced a separate workshop for advanced students and an open studio where students could watch Haines resolve his own problems in painting. Among his best-known works are "Last Gleam" and "Pasture".
