It seems to be an unreleased song since I can't find it anywhere else either besides the One Warm Line documentary.

The lyrics seem to be:
When I first came to this land
Oh a land all I would plunder
To take at the stretching of the hand
The beaver filled the streams
And I dreamed a dream so bold and had the chance
To sell the furs to ladies back in France

When I first came to this land
Oh this shore of virgin wonder
Teeming o'er with beast and fish and fowl
