The municipality strives to protect the interests of both individuals and the community as a whole, by reviewing and approving building permit applications before any work is done. Building Services enforces the Building Code Act and regulates compliance ensuring that buildings comply with:

  • the Ontario Building Code, which sets standards for the design and construction of buildings to meet objectives such as health, safety, fire protection, accessibility and resource conservation
  • the local zoning bylaw and other planning controls on buildings
  • other applicable legislation, including conservation authority approvals and certain requirements under the Environmental Protection Act.

If you're doing any construction, demolition, renovations or changing the use of a building please check whether you need a permit before you start on the project. 


Changes to your Property's Assessed Value due to renovations or new construction and Supplemental Billings

If the property you own is under construction, being renovated or is a newly constructed building, you may not be fully assessed for property tax purchases. If the change to the property was not processed the assessment roll by January 1st, you will be issued a supplementary tax bill(s) in the future.  MPAC can assess your property value for the current year plus previous two tax years for such changes and you will be issued a supplementary property tax bill based on the MPAC assessment changes for the current year plus the previous two tax years.  These bills will be issued upon receipt of the necessary assessment information from the Municipal Property Assessment Corporation and may be payable in less than two installments.

If you have purchased a newly constructed home for which the current tax assessment is based solely on the value of the land, please note that MPAC will be assessing your property for the value of the constructed home.   Supplementary tax bills for will be processed by the City when the assessment change information is received from MPAC.
