With new commuter rail service on the Stouffville Line in the 1990s, the drilling of two deep aquifer wells to secure safer water for a large, new development in the hamlet of Ballantrae in 1996, and the controversial expansion of the York-Durham Sewage System Big Pipe with additional water capacity from Lake Ontario, Whitchurch–Stouffville began a major self-transformation. Not unlike the late 19th century, responsible land and water stewardship, as well as the positive integration of many new residents annually into the community, define the challenges and opportunities for Whitchurch–Stouffville in the years to come.
