Fort York National Historic Site is a historic site of military fortifications and related buildings on the west side of downtown Toronto, Ontario, Canada. The fort was built by the British Army and Canadian militia troops in the late eighteenth and early nineteenth centuries, to defend the settlement and the new capital of the Upper Canada region from the threat of a military attack, principally from the newly independent United States.

The Fort is open year round and offers a number of services, including tours, exhibits, period room settings and seasonal demonstrations.
