First Toronto Post Office, National historic site and active post office in Old Toronto, Canada.
The First Toronto Post Office is a national historic site of Canada operating as a working post office on Adelaide Street East in Old Toronto. The late Georgian building houses both postal services and a small museum space with exhibits about early mail delivery and communication.
The post office opened in 1833 when the settlement was still called York, just before it was renamed Toronto. It was part of the British Royal Mail network, and it remains the oldest surviving building in Canada purpose-built for mail service still in operation.
The name "First Toronto Post Office" reflects its status as the original mail facility that served the town before it was even called Toronto. Visitors today can use it as a working post office, which gives the space a sense of continuity rather than a frozen past.
The building sits on Adelaide Street East in the heart of Old Toronto and is easy to reach on foot from other downtown landmarks. A visit works well as part of a walk through the old city center, where several other historic spots are nearby.
Letters mailed from here can be stamped with a reproduction of Toronto's original postmark from the 19th century. That means any letter sent from this address carries a small piece of the city's postal past along with it.
