O Canada; Our National Anthem - Ingrain This Into Your Heart & Soul.

If you are ever planning on becoming Canadian or are a Canadian - you should know our anthem by heart at least in one of our official languages (if not both).  Ingrain this into your heart.  Our ancestors may have died in battle under the Red Ensign, but know that there are many in uniform serving under this flag and have died in Afghanistan under service to this flag. 

English Version: 

O Canada!
Our home and native land!
True patriot love in all thy sons command.
With glowing hearts we see thee rise,
The True North strong and free!
From far and wide,
O Canada, we stand on guard for thee.
God keep our land glorious and free!
O Canada, we stand on guard for thee.
O Canada, we stand on guard for thee.

French Version:

O Canada! Terre de nos aïeux,
Ton front est ceint de fleurons glorieux!
Car ton bras sait porter l'épée,
Il sait porter la croix!
Ton histoire est une épopée
Des plus brillants exploits.
Et ta valeur, de foi trempée,
Protégera nos foyers et nos droits.
Protégera nos foyers et nos droits.

"O Canada" was proclaimed Canada's national anthem on July 1, 1980, 100 years after it was first sung on June 24, 1880. The music was composed by Calixa Lavallée, a well-known composer; French lyrics to accompany the music were written by Sir Adolphe-Basile Routhier. The song gained steadily in popularity. Many English versions have appeared over the years. The version on which the official English lyrics are based was written in 1908 by Mr. Justice Robert Stanley Weir. The official English version includes changes recommended in 1968 by a Special Joint Committee of the Senate and House of Commons. The French lyrics remain unaltered.
