Alterations and Demolition

Designated properties

Applications to alter designated properties under Section 33 of the Ontario Heritage Act require a Heritage Permit. 

Review of a request to alter a designated property generally includes the following steps:

1. Staff reviews the application to determine if the alteration impacts heritage attributes. If no, a review is not required
2. If yes, staff consult Heritage Oshawa for comment
3. Council reviews Heritage Oshawa's comments and will either approve, approve with conditions, or refuse

Designation does not prohibit alterations. Heritage Oshawa encourages alterations that restore or complement the heritage attributes of a property.

If an owner objects to a Council decision to refuse or apply conditions to a proposed alteration, they may appeal the decision to the Ontario Land Tribunal.

Alternatives to demolition

There are options to consider other than demolition, including:

• adaptive reuse of the building: keep the building and use it for a different purpose
• relocation: move the building to another location
• reclamation and deconstruction: salvage materials from a property before demolition
• partial retention: keep part of the structure on the property, such as the façade or exterior walls
• symbolic conservation: recover historic features and incorporate them into a new development
• record: document photos of the property
