So how is this Mac related?
I'd wager it has to do with people who are not familiar with the (most) eastern provinces and probably know it only as Newfoundland. Or just don't care.
I still find it amusing when some Newfies* make it a point that the proper name of the province Newfoundland AND Labrador. It's almost as if excluding Labrador from the name would offend that particular land mass.
* Before somebody gets all hot about me referring to Newfoundlanders as Newfies--I have very close friends who are all born and bred 'landers from the rock who refer to each other as well as themselves as Newfies and have no problem wearing that label of distinction with pride.
