Demolition Permit
A demolition permit is required to demolish, or partially demolish, a structure, greater than 10 square metres (108 square feet), except for farm buildings.
A permit is not required for the demolition of a farm building provided it is associated with and located on land devoted to the practice of farming and does not contain residential occupancy and as long as the structure being demolished isn’t subject to any other laws, such as the Ontario Heritage Act’
