Toronto Building Customer Service office locations:
Customer service counters are open Monday to Friday from 8:30 a.m. to 4:30 p.m.
Please sign in upon arrival to secure your place in line and ensure you are served as quickly as possible. In order that all customers can be served at the counter on the day that they arrive, it is necessary to arrive and sign in no later than 3:30 pm. We apologize for any inconvenience, but this will ensure that customers can be served prior to closing at 4:30 p.m.
