How did Lester B Pearson change the Canadian flag?

Lester B. Pearson, as Prime Minister of Canada from 1963 to 1968, played a pivotal role in the adoption of the current Canadian flag. He advocated for a distinct national symbol to replace the "Red Ensign," which was associated with Canada's colonial past. Pearson's government initiated a national debate and design competition, ultimately leading to the selection of the iconic red and white flag featuring a single stylized maple leaf. The new flag was officially adopted on February 15, 1965, marking a significant moment in Canada's national identity.
