The journey of 'O Canada' to its status as the national anthem began with its composition in 1880 by Calixa Lavallée, with lyrics penned by Adolphe-Basile Routhier. Over the decades, it was performed at numerous public events and became a symbol of national pride, especially during world wars when it resonated with sentiments of patriotism among Canadians. Although it was popular, it was not until 1980 that 'O Canada' was officially recognized by the Parliament of Canada as the national anthem, reflecting an evolving national identity and the desire for a distinct Canadian cultural expression. This decision coincided with Canada's celebration of its 113th anniversary and was part of a cultural movement towards recognizing and honoring national symbols, especially in light of the ongoing discussions about bilingualism and multiculturalism in Canada.

The formal adoption of 'O Canada' was marked by a significant debate within political circles, as various factions weighed in on the importance of having a national anthem that reflected both English and French-speaking Canadians. The anthem's bilingual lineage spoke to the core of Canada's identity as a nation that embraces its diverse populations. Following the official declaration, 'O Canada' was heard in schools, at sports events, and during official ceremonies, further embedding it within the day-to-day life of Canadians and reinforcing a sense of national pride. Over the years, various renditions and arrangements of the anthem have contributed to its popularity, showcasing different musical traditions across the country.
