What is an Official Plan?

The Town's Official Plan guides where and how land in our municipality should be used. More specifically, the Official Plan sets out:

  • where different types of development like housing, offices, shops, and roads will be located
  • where community uses like parks, trails, and schools will be needed, and
  • what should be protected, such as the natural environment, historic properties, and other special places, like Whitby’s waterfront and downtowns.

Land use planning in Ontario occurs in a “policy-led” system. Whitby's Official Plan is informed by the Ontario Planning Act, the Ontario Provincial Planning Statement and former Regional plans like Envision Durham.

Why are we reviewing the Whitby Official Plan now?

Whitby's population is forecasted to grow to approximately 240,000 by 2051. By 2031 alone, the Province of Ontario has mandated the Town to support the construction of 18,000 new homes in Whitby. This growth needs to be planned in a sustainable manner for today and future generations. Fortunately, Whitby already has a comprehensive Official Plan that was updated last in 2018.

This review focuses on updating key areas to plan for more housing and jobs, while also updating the existing Official Plan to align with recent changes made by both the Province. On January 01, 2025, land use planning authority was removed from the Region of Durham. Through this change, Whitby has inherited Envision Durham and will be incorporating its relevant policies through the Official Plan Review.

The Town of Whitby has now completed its five-year Official Plan Review to set policies that manage how Whitby should grow between now and 2051.
