“The flag is the symbol of the nation’s unity, for it, beyond any doubt, represents all the citizens of Canada without distinction of race, language, belief or opinion,” declared the Speaker of the Senate at the Inauguration of the new flag in 1965.
"On February 15, 1965, our national flag was raised for the first time on Parliament Hill. Canada was just two years away from centennial celebrations when the maple leaf flag was made official by Royal Proclamation. In 1996, February 15 was declared National Flag of Canada Day and has been observed every year since.
February 15, 2015, will mark the 50th anniversary of the National Flag of Canada. This special Flag Day is the perfect opportunity to learn more about how our flag was created and what it means to us.
Canadians are invited to join together and celebrate our flag by organizing their own public events or by showing their pride on social media."
