What is the nickname of the official anthem of Canada, "O Canada"?

The official anthem of Canada, "O Canada," is most commonly referred to as the National Anthem. This designation reflects its status as the official song that represents Canada and embodies the country's values, traditions, and spirit. "O Canada" was adopted as the national anthem in 1980, solidifying its significance in Canadian culture and national identity. The term "national anthem" is widely recognized and used in various contexts, including government proceedings, sporting events, and public celebrations, making it the most appropriate and accurate nickname for this anthem.

In contrast, other options such as "National Song" or "Official Hymn" do not hold the same official status and recognition as "National Anthem." "Pride of Canada" is more of a thematic phrase and does not serve as an official title or nickname for the anthem.
