Flag of Canada replaces Canadian Red Ensign
The National Flag of Canada (French: le Drapeau national du Canada), often simply referred to as the Canadian flag or, unofficially, as the maple leaf flag or l'Unifolié (French: [l‿ynifɔlje]; lit. 'the one-leafed'), consists of a red field with a white square at its centre in the ratio of 1∶2∶1, in which is featured a stylized, red, 11-pointed maple leaf charged in the centre. It is the first flag to have been adopted by both houses of Parliament and officially proclaimed by the Canadian monarch as the country's official national flag. The flag has become the predominant and most recognizable national symbol of Canada.
In 1964, Prime Minister Lester B. Pearson formed a committee to resolve the ongoing issue of the lack of an official Canadian flag, sparking a serious debate about a flag change to replace the Union Flag. Out of three choices, the maple leaf design by George Stanley, based on the flag of the Royal Military College of Canada, was selected. The flag made its first official appearance on February 15, 1965; the date is now celebrated annually as National Flag of Canada Day.
The Canadian Red Ensign was in unofficial use since the 1860s and officially approved by a 1945 Order in Council for use "wherever place or occasion may make it desirable to fly a distinctive Canadian flag". Also, the Royal Union Flag remains an official flag in Canada, to symbolize Canada's allegiance to the monarch and membership in the Commonwealth of Nations. There is no law dictating how the national flag is to be treated, but there are conventions and protocols to guide how it is to be displayed and its place in the order of precedence of flags, which gives it primacy over the aforementioned and most other flags.
Many different flags created for use by Canadian officials, government bodies, and military forces contain the maple leaf motif in some fashion, either by having the Canadian flag charged in the canton or by including maple leaves in the design. The Canadian flag also appears on the government's wordmark.History
Early flags
The Saint George's Cross was carried by John Cabot when he reached Newfoundland in 1497. In 1534, Jacques Cartier planted a cross in Gaspé bearing the French royal coat of arms with the fleurs-de-lis. The Royal Banner of France or  "Bourbon Flag" held a position of some prominence in New France, with the evolving variations of French military flags being used over time.As the de facto British national flag, the Union Flag (commonly known as the "Union Jack") was used similarly in Canada from the time of British settlement in Nova Scotia after 1621. Its use continued after Canada's legislative independence from the United Kingdom in 1931 until the adoption of the current flag in 1965.Shortly after Canadian Confederation in 1867, the need for distinctive Canadian flags emerged. The first Canadian flag was that then used as the flag of the governor general of Canada, a Union Flag with a shield in the centre bearing the quartered arms of Ontario, Quebec, Nova Scotia and New Brunswick, surrounded by a wreath of maple leaves. In 1870, the Red Ensign, with the addition of the Canadian composite shield in the fly, began to be used unofficially on land and sea and was known as the Canadian Red Ensign. As new provinces joined the Confederation, their arms were added to the shield. In 1892, the British admiralty approved the use of the Red Ensign for Canadian use at sea.
The composite shield was replaced with the coat of arms of Canada upon its grant in 1921 and, in 1924, an Order in Council approved its use for Canadian government buildings abroad. In 1925, Prime Minister William Lyon Mackenzie King established a committee to design a flag to be used at home, but it was dissolved before the final report could be delivered. Despite the failure of the committee to solve the issue, public sentiment in the 1920s was in favour of fixing the flag problem for Canada. New designs were proposed in 1927, 1931, and 1939.By the Second World War, the Red Ensign was viewed as Canada's de facto national flag. A joint committee of the Senate and House of Commons was appointed on November 8, 1945, to recommend a national flag to officially adopt. It received 2,409 designs from the public and was addressed by the director of the Historical Section of the Canadian Army, Archer Fortescue Duguid, who pointed out that red and white were Canada's official colours and there was already an emblem representing the country: three joined maple leaves seen on the escutcheon of the Canadian coat of arms. By May 9 the following year, the committee reported back with a recommendation "that the national flag of Canada should be the Canadian red ensign with a maple leaf in autumn golden colours in a bordered background of white". The Legislative Assembly of Quebec had urged the committee to not include any of what it deemed as "foreign symbols", including the Union Flag, and Mackenzie King, then still prime minister, declined to act on the report; fearing it may lead to political instability. As a result, the Union Flag was kept as a national flag, and the order to fly the Canadian Red Ensign at government buildings was maintained.Adoption
The new national flag was inaugurated on February 15 of the same year at an official ceremony held on Parliament Hill in Ottawa, in the presence of Governor General Major-General Georges Vanier, the Prime Minister, other members of the Cabinet, and Canadian parliamentarians. The Red Ensign was lowered at the stroke of noon and the new maple leaf flag was raised. The crowd sang "O Canada" followed by "God Save the Queen". Of the flag, Vanier said "[it] will symbolize to each of us—and to the world—the unity of purpose and high resolve to which destiny beckons us". Maurice Bourget, Speaker of the Senate, said: "The flag is the symbol of the nation's unity, for it, beyond any doubt, represents all the citizens of Canada without distinction of race, language, belief, or opinion." Yet there was still opposition to the change, and Stanley's life was even threatened for having "assassinated the flag". In spite of this, Stanley attended the flag-raising ceremony.At the time of the 50th anniversary of the flag, the government—held by the Conservative Party—was criticized for the lack of an official ceremony dedicated to the date; accusations of partisanship were levelled. Minister of Canadian Heritage Shelly Glover denied the charges and others, including Liberal Members of Parliament, pointed to community events taking place around the country. Governor General David Johnston did, though, preside at an official ceremony at Confederation Park in Ottawa, integrated with Winterlude. He said "[t]he National Flag of Canada is so embedded in our national life and so emblematic of our national purpose that we simply cannot imagine our country without it." Queen Elizabeth II stated: "On this, the 50th anniversary of the National Flag of Canada, I am pleased to join with all Canadians in the celebration of this unique and cherished symbol of our country and identity." A commemorative stamp and coin were issued by Canada Post and the Royal Canadian Mint, respectively.
