The Red Ensign served as the country's civil ensign from 1892 to 1965 when it was replaced by today's Maple Leaf flag. The flag bore various forms of the shield from the Canadian coat of arms in its fly during the period of its use. From 1921 until 1957, the Canadian Red Ensign was virtually the same, except that the leaves in the coat of arms were green, and there was a slight alteration to the Irish harp (the earlier version having a woman's bust as part of the harp). A blue ensign, also bearing the shield of the Canadian coat of arms, was the jack flown by the Royal Canadian Navy and the ensign of other ships owned by the Canadian government until 1965. From 1865 until Canadian Confederation in 1867, the United Province of Canada could also have used a blue ensign, but there is little evidence such a flag was ever used. In Otto Reinhold Jacobi's painting of the new Parliament Buildings in 1866, a Red Ensign flies from the tower of the East Block.
