How to submit an application

Prior to submission, ensure that all necessary and applicable permissions and approvals are met. Applications may need site approval, minor variance approval, or amendments to the zoning bylaw or official plan. View the rules and requirements on the business, planning and development page. The Planning team must provide approval before you apply for a permit to build. 

A complete application must be submitted with all the required forms, documents and applicable drawings. Building permit fees (see below) are required at the time of submission. Additional fees such as development charges and parkland will be calculated and invoiced at permit issuance.

Plan and book inspections
