The population of North York, along with other cities in Ontario, get their water from Lake Ontario (“Drinking water treatment,” 2015). Before any water can be consumed, it is first treated at water treatment plants spread throughout the city; plants include the R.C. Harris, F.J. Horgan, R.L. Clark, and Island, but the main water treatment plant that provides York Region’s population with clean and safe drinking water is the R.C. Harris water treatment plant. The R.C Harris plant can be found at the foot of Victoria Park Ave (Marsh, n.d.).
Here’s the R.C Harris plant:
