Down at Fort York, amongst the War of 1812 buildings and the construction site of the new visitors centre, lies a grate for a catch basin that may be the oldest in the city.
The clues to the grate’s age are embossed into the metal. The letters “TWB” (the T is slightly hidden by a grass blade) indicate the agency responsible for this piece of infrastructure is the Toronto Board of Water, a 19th century department of the City of Toronto. Also embedded is “88”, which we can assume is for 1888 and not 1988.
You can see the grate for yourself if you enter the Fort from the parking lot (west side); it’s about 50 metres south of the main walkway before you enter through the Fort’s wooden gates.
There are very few records that can help determine the location of the oldest pieces of infrastructure in the city. If you think there is an older grate somewhere let us know in the comment section.
