The first governor general's flag was adopted in 1870 and followed the design of other viceregal flags in use throughout the British Empire at the time: a Union Flag defaced with the shield of the coat of arms of Canada; though, in contrast to other imperial governors, the wreath surrounding the central badge was one of maple instead of laurel leaves. The design was updated in 1921, to incorporate changes to the appearance of Canada's coat of arms, and again in 1931, to reflect developments in Canada's constitutional structure brought about by the Statute of Westminster, whereby the governor general became the personal representative of the monarch of Canada, rather than a representative of the British monarch in Canada, as it was previously.
