"The Anthem"
This ad features famous moments from Canadian history (including the pounding of the Last Spike and the raising of the Maple Leaf flag), as well as a variety of "average Canadians", singing a song extolling the virtues of Canada and its citizens.
Molson also released an mp3 version of the song, which is entirely in English and sings rather than speaks the line "the one we call Canadian".
