What is the national anthem of Canada?

The national anthem of Canada is "O Canada." This anthem was officially adopted in 1980, although it was composed many years earlier, in 1880. It reflects Canadian pride and values, celebrating the beauty of the country and the spirit of its people. The lyrics convey themes of unity and patriotism, making it an important symbol of national identity during ceremonies and events that honor Canada.

In contrast, "God Save the Queen" is a royal anthem associated with the British monarchy and is traditionally used in Commonwealth countries, but it does not represent Canada's national identity in the same way. "The Maple Leaf Forever" is a song that expresses Canadian nationalism but is not the official anthem. "True North Strong and Free" is a phrase from the anthem and represents Canada's reputation, but it is not the title of an anthem. Thus, the only correct choice as the national anthem of Canada is "O Canada."
