2026 Official Plan approval status
Ontario approved the Town’s new Official Plan in part on September 25, 2025, with 131 modifications. On September 18, 2026, the Province refused the portions previously withheld from approval. Separately, the Town’s employment-area policy and mapping amendment took effect July 13, 2026 after no appeals were filed. These decisions are not equivalent to the entire originally adopted plan taking effect unchanged. Confirm the currently applicable Official Plan schedules, zoning by-law and any site-specific restrictions before assuming a property can be redeveloped or used differently.

Zoning and Property-Specific Due Diligence
Before buying for a specific use or starting construction, confirm the current zoning and any site-specific provisions. Rural properties may have additional considerations involving private servicing, agricultural uses, environmental features and conservation regulation.
Building Permits and Renovations
Renovations involving structural work, additions, plumbing, changes of use, new dwelling units and many accessory structures can require building permits and other approvals. Zoning compliance should be checked before relying on development potential.
See our Ontario Renovation Guides and Zoning & Permits hub.
Additional Residential Units in Whitchurch-Stouffville
Whitchurch-Stouffville has updated its zoning framework for additional residential units. The Town’s ARU initiative was designed to permit up to three dwelling units on fully serviced residential properties, consistent with provincial requirements. An ARU can include a secondary suite or a detached residential unit where the zoning and other requirements permit it.
Do not assume that the same permissions apply to rural or privately serviced properties. Servicing, zoning, parking, building-code and environmental constraints should be confirmed for the specific lot before relying on additional-unit potential.
See our Additional Rental Units in Ontario guide.

Whitchurch-Stouffville Property FAQ
Can a fully serviced residential property have three dwelling units?
The Town’s ARU zoning update was developed to enable up to three dwelling units on fully serviced residential lots, subject to the applicable zoning and other requirements.
Are rural properties treated the same way?
Not necessarily. Private servicing, environmental constraints and different zoning provisions can change what is permitted on rural properties.
Should I verify an existing basement apartment?
Yes. An existing kitchen, entrance or rental history does not by itself establish zoning, building-permit or other compliance.
