Flag Canada 1921 Version 1

The Canadian Red Ensign is a former flag of Canada, used by the federal government though it was never officially adopted by the Parliament of Canada. It is a British Red Ensign, featuring the Union Flag in the canton, defaced with the shield of the Coat of Arms of Canada
In 1921, the Government of Canada asked King George V to order a new coat of arms for Canada. The College of Arms thus designed a suitable coat of arms of Canada. The new shield was displayed on the Red Ensign, thus producing a new version of the Canadian Red Ensign in 1922. In 1924, the Red Ensign was approved for use on Canadian government buildings outside Canada.
The Canadian Red Ensign continues to be flown by some Canadians, especially monarchists, other traditionalists, those who cherish Canada's British heritage.
