Thornhill Heritage Conservation District Plan Update

The City is updating the Thornhill Heritage Conservation District Plan to determine what is required to continue protecting the area’s heritage properties and landscapes. Stantec, a multi-disciplinary consulting firm was retained in 2024 to undertake a three-phase project consisting of: 

The Study (Phase One, preparing background information in a report that informs the Plan Update) The purpose of this review is to understand how the THCD functions and identify changes that have occurred over time. This information will be used to determine the effectiveness of the THCD through identification of the district’s strengths, weaknesses, opportunities, and threats (SWOT).  The SWOT report is now complete and available in this link (SWOT); it will feed into the Phase Two of the Plan update. 

The Plan (Phase Two, compiling the findings of The Study into a comprehensive Update) 

The Inventory (Phase Three, updating the information of the THCD Plan boundary and the properties within it).
