Licences and permits to open a heating or hvac contractor in Toronto

We found three licences, permits and registrations that can apply when you open a heating or hvac contractor in Toronto, starting with the Heating Contractor licence. One of them applies only in certain situations, noted on each item. They are handled by two different bodies: Municipal Licensing & Standards and the Technical Standards and Safety Authority (TSSA).

One item is provincial rather than municipal — the TSSA licensing — so expect to deal with the Technical Standards and Safety Authority (TSSA) as well as the City. Where a combined application and licence fee is published, it is $495.12. One has no fee listed on the page we reviewed.

The notes mention a certificate or exam; those steps depend on other people's schedules, so they are worth starting early.
