Plumber in North York

North York was mostly farmland until the Second World War, then filled with post-war houses: in the City's 2021 profile of the area, about a quarter of homes were built before 1961 and a third between 1961 and 1980. Don Mills, planned between 1952 and 1965, is typical. The oldest of those houses can still have galvanized steel water pipe and cast iron drains, and the City says a house built before the mid-1950s may have a lead water service pipe. Toronto's water comes from Lake Ontario, at about 119 mg/L of hardness, and the City says softeners are usually not needed. The north of the city floods in big storms: on July 8, 2013, North York logged 991 basement flooding calls, and Bayview Village, Willowdale Park and Don Mills–York Mills are among the City's basement flooding study areas.
