You're quite wrong about that of course, but quite understandable being that you're the raving Anglophile you are. The truth of course is that "The Maple Leaf Forever" was their last good anthem.

Actually, "The Maple Leaf Forever" is only merely an informal anthem, much like "America the Beautiful" or "God Bless America" here.
And "Waltzing Matilda" is NOT the Australian national anthem, which surprised me, because I thought it was.
Apparently Canada has two official anthems, "O Canada" and "God Save the Queen," the second being played when royalty is present.
"God Save the Queen" is the national anthem of the United Kingdom. Like many aspects of British constitutional life, its official status derives from custom and use, not from Royal Proclamation or Act of Parliament. In general only one or two verses are sung, but on rare occasions three.
"God Save the King/Queen" was exported around the world via the expansion of the British Empire, serving as each country's national anthem. Throughout the Empire's evolution into the Commonwealth of Nations, the song declined in use in most states which became independent. In some countries it remains as one of the official national anthems, such as in New Zealand, or as an official royal anthem, as is the case in Canada, Australia, Jamaica, Isle of Man, and Tuvalu, to be played during formal ceremonies involving national royalty or vice-royalty. The National Anthem of the United Kingdom is also used in all British Overseas Territories.
In Australia, the song has standing through a Royal Proclamation issued by Governor-General Sir Ninian Stephen on 19 April 1984. It was declared the Royal Anthem and is to be played when the Monarch or a member of the Royal Family is present. The same Proclamation made "Advance Australia Fair" the National Anthem and the basis for the Vice-Regal Salute (the first four and last two bars of the Anthem).
In Canada "God Save the Queen" has not been adopted as the Royal Anthem by statute or proclamation, however it has come to be used as such through convention, and is sometimes sung together with "O Canada" at public events. The Department of National Defence and the Canadian Forces regulates that "God Save the Queen" be played as a salute to the monarch and other members of the Canadian Royal Family, though it may also be used as a hymn, or prayer. The words are not to be sung when the song is played as a military Royal Salute, and is abbreviated to the first three lines while arms are being presented.
The New Zealand national anthems are "God Save the Queen" and "God Defend New Zealand". However, "God Save the Queen" is most often only played when the Sovereign, Governor-General or other member of the Royal Family is present, or on certain occasions such as Anzac Day.
