3x5 Canadian Province of Ontario Flag

The current Flag of Ontario was proclaimed by the Flag Act on May 21, 1965. The flag is a defaced Red Ensign, with the Union Flag in the upper left corner and the Ontario shield of arms in the fly. Before 1965 the Canadian Red Ensign had flown outside the legislature and government buildings. It was replaced by the Canadian flag in 1965, when Premier John Robarts then proposed that Ontario have its own flag and that it be a Red Ensign like the previous Canadian flag, except with the Ontario coat of arms.
