(Glossary of Heraldic Terms)
A mural crown over the shield in the arms of a community usually indicates that the place is or was a fortified settlement. In the Arms of Toronto reference to Old Fort York is made by the display of the mural crown above the shield. This is surmounted by a beaver, which here is intended to refer to industry and also to the fact that Old Fort York was once a centre of fur trade with the Natives in that region. The badge of Toronto does honour to that city by using the crest from the civic arms with necessary and appropriate difference by having the beaver hold a fid which associates the Toronto beaver with things nautical.
