The Canadian Flag is the national flag of Canada. It has been in use since 1967 on Canada's Centennial (100 year anniversary) of Independence, sorry I mean Confederation. No Independence.
The flag of Canada is twice as long as it is wide. Keep in mind that no other flag in the world has these dimensions.
I have included all the historical flags of Canada as well. AND that means the Red Ensign is in this list as that flag was used
Check out the Provincial Flags as well.
