Applications and forms

Filing information

Include all required supporting documentation such as land surveys and tax clearance.
If the Department of Finance approves the initial request, you must then submit it to the Department of Buildings for approval. If the Department of Buildings approves the request, you must tell the Department of Finance that you want to complete the apportionment or merger.
The Tax Map Unit will process applications in the order that they are received. Initial review of application(s) for processing is 30 business days.
To avoid processing delays, ensure that all applications contain the correct and required documents.
Property owners must resolve certain outstanding judgment summonses adjudicated by the Environmental Control Board (ECB) before applying to divide or merge properties (also known as “tax map changes”). Check for outstanding judgment summonses at CityPay.
If there are any issues with the application, you will receive a notification and a list of objections. The application needs to be picked up from our office for resubmission during regular business hours.

New Lot Assignment and Fees:

The Tax Map Office issues lot numbers for all apportionments, including condominiums. Finance collects $73 for each lot number, payable at the time of the initial application.
Lots are tentative until final approval is received from the Tax Map Office.
Even if a fee was previously paid, a new fee will be required for each tax lot if any of the circumstances apply:
1. Owner changes
2. Lot subdivision configuration changes
3. Condo subdivision and/or number of units changes
4. Tentative lots expire after one year
Tax map certification: $10.00
