I think that was printed in the USA and not Canada.
Sorry to correct you, but that is incorrect.
You are referring to the colour, this is the Name of the town.
It may be, Mr. Wheeler, (An American) used his influence in naming the town, but GRAY is it
Where the label was printed, is unknown to me.
Gray Rocks was founded in 1905 by George Wheeler, an American from New Hampshire who arrived in the region in 1894 as a lumberjack. Standing in front of the 105-room hotel: the Sugar Loaf mountain (189 meters (620 feet)), with 22 ski runs, renowned ski center for several decades. And behind, the Ouimet lake.
Gray Rocks was a year-round privately owned resort in the Laurentian Mountains of Quebec, Canada, first developed as a ski destination on Sugarloaf Hill (French: Le Pain de Sucre). The ski hill had 22 downhill trails: 4 easy, 10 intermediate, 8 expert (of which 2 were "double diamond"). Also available was a snowboarding park and instruction from the Snow Eagle Ski School.
