Old Mill is an Etobicoke landmark area on the west bank of the Humber River, north of Bloor Street, named for the mills that stood here for nearly a century. Around 1793 the colonial government built a sawmill on the site, known as the King's Mill and remembered as Toronto's first industrial building. Several mills followed, and the last, part of merchant William Gamble's milling business, was built in the late 1840s. It burned in 1881, and its stone ruins stood beside the river for more than a hundred years.

In 1914 developer Robert Home Smith opened the Old Mill Tea Garden beside the ruins, the first amenity of his Humber Valley Surveys, which included a subdivision called The Old Mill. The City of Etobicoke designated the property a heritage site in 1983. The ruins were taken down in 2000 and an inn in the style of the 1914 tearoom opened in 2001, close to Old Mill station on Line 2. Across the river, the houses of the east bank lie in the former City of York. Etobicoke became part of the amalgamated City of Toronto in 1998.

The Old Mill tee is for the neighbours on both banks of the Humber.
