The Zoning By-law manages the present and future land use in the City. It is a tool used to implement the Official Plan's vision for the City on a day-to-day basis. The Zoning By-law divides the City into land use zones. Each zone has a list of permitted land uses and a set of regulations. For example, in the "R2" - Residential Zone Two you may build a duplex, but you may not build an office. There are regulations that apply to specific uses permitted in each zone such as required setbacks and maximum height. There are also general regulations that apply to all properties in any zone such as parking.

The City of Thunder Bay passed its Zoning By-law in 2010. Since the City has recently updated the Official Plan since then, the Zoning By-law must also be updated to reflect the changes.

If you can't meet a regulation, you may need a minor variance or a zoning by-law amendment. You can visit the planning applications page for more information. You must consult with Planning Services staff before applying.

Please note: if you are proposing to change the use of a property, you may require a Record of Site Condition through the Ministry of Environment, Conservation and Parks. This can be a time consuming and expensive process. Please contact the Planning Services Division about this matter before you move forward with any project. 

See the Building and Planning page for more information about developing in our City.

Zoning enquiries

Property information reports

We recommend this service when you are thinking about buying or leasing a property. Property Information Reports give zoning and building information about a specific property. They include the applicable zoning and whether the proposed use is thought to be a permitted use on that property. They also note whether Site Plan Approval is needed and if there are any open or revoked building permits or orders.

If you provide a survey, City staff will also complete a zoning review of the lot and buildings. This includes whether the lot and buildings follow regulations such as minimum lot size, required yards, etc.

The report can also be used to show legal non-conforming status. The Applicant is responsible for providing any materials necessary to meet the requirements for legal non-conforming status. 

You must submit a completed request form to Building Services with the $100.00 application fee. You may provide a survey, but this is not required. You may need to submit extra materials to prove legal non-conforming status.
