When a permit submission is received by Building Services, a permit file name is created. Building Services will review it for completion. An email will be sent to the applicant acknowledging the submission and providing the building permit file number, which is to be used for all future correspondence. This will be followed by an email after permit review (see below) stating any outstanding documents if the submission is not deemed to be complete. 

Once the Plans Examiner has completed a review of the permit submission, building permit fees, any concerns, or outstanding information required will be sent to the applicant via email.

After approval and payment of fees for an electronically submitted application and issuance of the permit by Building Services, you will receive your Reviewed Drawing Set electronically via email. Please print a set of all approved drawings or specifications (in colour) and ensure this reviewed drawing set is available to the inspector on-site for every inspection.

Where a submission is being made to address a deficiency identified by a Building Inspector/Examiner, an electronic copy of the revised plans shall be submitted with the changes clearly labelled with revisions noted. A fee for revisions may be applicable as per Building By-Law #2014-18.
