I believe this is most likely an early 1990s sign, maybe a little older. I saw online said it was bought by Molson in 1989 and the Montreal plant was closed down a few years later. This shows the original Frontenac Breweries on the label, which was the original company that was bought out in 1926. Great winter scene and colorful with a nice "bottle" in the artwork.
