Canada (Maple Leaf flag)
Who & why: Prime Minister Lester B. Pearson champions a new, distinctly Canadian flag, triggering the bitter 1964 "Great Flag Debate" in Parliament between those wanting a design free of British symbols and those defending the Red Ensign's imperial heritage. The Maple Leaf flag is adopted by parliamentary vote and raised for the first time on 15 February 1965, now marked annually as National Flag of Canada Day. Canadian sovereignty itself completes gradually and peacefully over this same broad era: the 1931 Statute of Westminster grants legislative independence, and the 1982 Constitution Act finally patriates the constitution, severing the last formal legal tie to the UK Parliament.
What it represents: a red maple leaf, long an unofficial Canadian emblem, centered on a white square between two red bars — deliberately free of any British or French imperial symbol.
Wikipedia says the House of Commons passed the design 163 to 78 on 15 December 1964, the Senate approved it two days later, Queen Elizabeth II signed the royal proclamation on 28 January 1965, and the flag was inaugurated on Parliament Hill on 15 February 1965; its all-party committee voted 15 to 0 for George Stanley's single-leaf design. FOTW says Parliament adopted the National Flag on 22 October 1964, certified it on 28 January 1965, and that it was proclaimed by the Queen and took effect on 15 February 1965, after a «33-day debate».
