Pefferlaw is a community within the Town of Georgina, located 3 kilometres south of the southeastern shores of Lake Simcoe and in the eastern end of the town. A river, known officially as the Pefferlaw River, runs just south of the community's commercial district. Pefferlaw is passed on the north by Highway 48 and Lake Ridge Road (Durham Road 23) to the east, and is serviced by Pefferlaw Road which links these two traffic arteries. Area code 905 is bounded to the west, but Pefferlaw along with Virginia Beach, Udora and Port Bolster remains in the 705 area code. The Canadian National railway passes through Pefferlaw and, until the early 1990s, served a train station in the community's commercial district.
