Canada - Breweries

Steam Whistle Brewing is a brewery in Toronto, Ontario, Canada and was founded in 2000. The brewery occupies Bays 1-14 within a building known as the John Street Roundhouse. Built in 1929, it was previously the home of a Canadian Pacific Railway steam locomotive repair facility, however the logo and name of the brewery is meant to evoke an image of steam rushing from a factory's whistle signalling the end of the work day, not from a steam train.

Over the years the brand identity is updated and re-launched with subtle changes, a change of Logo or a new font.
Sometimes this brand update is done by the new owners after a brewery has been sold, other times just to give the brand a fresh new look on the ever growing market.

Below are some notes to help identify some of these changes and an aid to reference the year of the glass.
