Since 1996, February 15 is the day it is celebrated. The day commemorates the inauguration of the Flag of Canada on that date in 1965. The day is marked by flying the flag, occasional public ceremonies, and educational programs in schools. It is not a public holiday, although there has been discussion about creating one.
The Maple Leaf flag replaced the Canadian Red Ensign, which had been in conventional use as the Canadian national flag since 1868. Canada is the second largest country in the world.
