If you are missing a required form, supporting documents or a fee, a permit coordinator will review your application and provide, in writing, any item which may be missing from the application. Only when all forms, documents and fees are received can an application be deemed complete.

The above timelines are for complete permit applications.  A complete application is one that meets zoning requirements, all applicable laws & the submitted drawings provide all the required information. Please be advised that staff will provide assistance to the applicant but must refrain from acting in the capacity of a designer.
At each stage of the review, you may receive review comments in writing from staff. Your designer will need to address these comments. Updated documentation will need to be provided by the applicant or designer. If you have questions regarding a review, please contact the staff member listed on the review for clarification. Staff will re-review the revised documentation. Once review comments are issued, the review period time frames set out by the Ontario Building Code no longer apply to the application.
