Georgetown is a community in the Greater Toronto Area of Ontario, located west of Toronto, on the Credit River, in the Town of Halton Hills, Ontario.

Georgetown takes its name from George Kennedy, who settled in the area in 1821. He built a sawmill, grist mill, foundry and a woollen mill, which fostered the early economic development of the area.

1837 was the year that two men, probably in the employ of George Kenedy, purchased his woollen mill operation. William and James Barber, both trained as carders and clothiers, purchased the mill and the surrounding 13 acres (53,000 m²) for 750 pounds sterling. To finace this large purchase price, Joseph and Robert Barber joined their brothers in the operation. James Barber built his home where the mill road joined the 8th line (Main Street and Park Avenue).
