Design | A red field with the flag of the Royal Union Flag in the canton defaced with the shield of the Ontario coat of arms. |
The flag of Ontario is a defaced Red Ensign, with the Royal Union Flag in the canton and the Ontario shield of arms in the fly. The flag of Ontario was derived from the Canadian Red Ensign, which was used as a civil ensign and as a de facto flag of Canada from the late 19th century to 1965. It was adopted in a period when many Canadian provinces adopted their own flags.[2] May 21 is Ontario Flag Day.
