This is the coat-of-arms visible on the clock tower in yesterday's pic. It was originally installed on the Yorkville Town Hall, which was located around the corner on Yonge St, when the hall was built in 1859. The Village of Yorkville became part off Toronto in 1883 but I'm not sure when the town hall was demolished and the coat-of-arms moved to the firehall. The symbols represent the occupations of the first councillors of the village - a brewer, a bricklayer, a carpenter, a blacksmith, and a butcher.
The letters below each symbol stand for the last initial of the respective councillor. The Beaver is the official animal of Canada and has been used on coats-of-arms since the 1600s.
