American flag: The 50 stars on the flag represent the 50 U.S. states and the 13 stripes represent the original Thirteen Colonies that rebelled against the British Crown and became the first states in the Union. Canadian flag: The maple leaf has served as a symbol celebrating the nature and environment of what is now Canada since the 1700s.[7] The number of points on the leaf has no significance on the flag; they do not, for instance, represent the ten provinces plus one point for the territories, such as the Australian Commonwealth Star denotes.[8] The number and arrangement of the points of the maple leaf were chosen after wind tunnel tests showed the current design to be the least blurry of the various designs when tested under high wind conditions.[9] The image of the maple leaf used on the flag was designed by Jacques Saint-Cyr.[10] In 1921, King George V proclaimed the official colours of Canada as red, from Saint George's Cross, and white, from the French royal emblem since King Charles VII.
