The name was officially changed to Canada Day on October 27, 1982. However, many Canadians had already been informally referring to the holiday as "Canada Day" for a number of years before the official name change.
The Maple Leaf
The current flag of Canada was approved by the House of Commons on December 15, 1964. The flag was later approved by Queen Elizabeth II, an order which took effect on February 15, 1965. In 1921, King George V proclaimed the official colours of Canada as red, from the Saint George's Cross, and white, from the French royal emblem since King Charles VII.
As early as 1700, the maple leaf served as a symbol celebrating the nature and environment of what is now Canada. The number of points on the leaf has no significance; they do not, for instance, represent the ten provinces plus one point for the territories. In fact, some of the very first Canadian flags made had maple leaves of variously 13 and 15 points or more. The points of the maple leaf were determined by taking various designs and putting them in a wind tunnel to see what looks the best while moving. It is easily one of the most recognized flags in the world, next to the Union Jack and the Star Spangled Banner.
