Haven't heard a thing about it. They just cancelled calls in the Province of Quebec because of the economy and are keeping the ship doing coastal Canada New England. They'd have a hard time getting anything big enough in there.
the great lakes are more than larg enough to get a cruis ship in if 1000 ft freighters can go through a cruis ship should be able. I seen a picture of a small cruis ship docked in Dulth MN.
