OK, here are the official lyrics from the Government of Canada Canadian Heritage site (op cit – Joe Offer). This version has been in use since the late sixties so it's about time we all knew the right words; especially those of us who call ourselves singers with repertoires of scores, if not hundreds of songs.

OFFICIAL LYRICS OF O CANADA!

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.
