Given royal approval in October 1965 by Her Majesty Queen Elizabeth II and officially proclaimed on May 12, 1966, the flag of Manitoba consists of the Red Ensign with the Armorial Bearings centred in the right half. The Red Ensign was, at the time, the flag of Canada.

The Shield is topped by St. George's Cross on a white background, representing King George III and symbolizing British heritage. The bison represents the once-vast herds of bison which once roamed freely throughout the province and provided food and clothing not only to the Aboriginals, but to the early settlers as well.
