Many years ago I heard on a CBC News program,"MIDDAY", that the Canadian flag, which flies on top of The Peace Tower @ The Parliament Hill Building in Ottawa, was replaced every day, and any citizen wishing to receive one could do so by simply writing and asking for one.They would then send you one by mail with the date that it actually flew on.
This morning in my mail box, I was pleasantly surprised to find mine. It is actually 15' X 7' in size... Quite a large & beautiful flag !
