Well, I don't know much about Canadian law,...hell, I don't know much about Canada, for that matter; however, I have by a cd by a GREAT
Canadian band from Newfoundland known as the Irish Descendants and on their album, "Best Of" they indicate that it is a, "BMI Canada, Ltd." song. You might start there, or, simply Google the song or the author and then who knows what kind of information you'll come up with or what interesting roads you may go down. Have fun, and, pick up an Irish Descendants disc while you're at it. Cheers.
