Hi, have upcoming US > YYZ (2.5 hr layover) > Europe all on Air Canada metal, have AC 25k but also Star Gold thru United (albeit I am presently working a status challenge with United). Believe I have access to the Maple Leaf Lounge in the international area due to Star Gold? And, is it better than the Plaza Premium lounge in the international area? Particularly interested in which might have substantive vegetarian options.
