The Canada pavillion movie is called "O Canada", the song is entitled
"Canada (You're a Lifetime Journey)".
Perhaps the fact that half the song is in French is what is causing your problem.
I afraid can't help you with the all the lyrics (yes, I'm Canadian, but no, I don't speak French)
Canada, (Canada), my Canada (mon Canada)
You're a lifetime journey for the traveler (les voyager)
Canada, (Canada) my Canada (mon Canada)
You're a lifeline of wonder on this planet earth (Canada)
Canada, you are far to vast and beautiful for words to ever really tell
Canada, 10,000 dawns and sunsets I could see, and still not know you well.
(French)
Canada, (Canada) my Canada (mon Canada)
(French)
Canada, (Canada), my Canada (mon Canada)
(French)
Canada, (French)
People from around the world have settled in your land,
For the heritage in Canada they stand, side by side and hand in hand.
Canada, (Canada) my Canada (mon Canada)
You're a lifeline of wonder on this planet earth
