Builders and contractors
Requirements for final inspection have changed
Enbridge Gas now requires an “Appliance Installer Validation Form” be completed and attached to the primary heating appliance, and any other appliance requiring setup and commissioning. The form confirms the requirements of CSA B149.1 section 4.3 have been fulfilled by the installer, and if the appliance is used during construction of the house, that the construction heat requirements have been met.
You can access this from through:
Request a meter activation for temporary heat or inspections with the online form.
Read the Guidelines to help you understand more about using natural gas for newly constructed commercial properties
Need heat for construction?
Whether you use a portable heater or an approved appliance for construction heat, we can help.
Request for meter activation
Send a request for meter activation for temporary heat.
A charge of $70+hst per premise will be applied to your bill.
Note: For Construction Heat, only manufacturer’s certified installation instructions indicating acceptability of the appliance for construction heat use will be accepted.
Finishing heatAs furnace manufacturers have incorporated construction use instructions for their appliances, the TSSA is no longer acknowledging the need for the finishing heat process. Enbridge Gas will be discontinuing the use of finishing heat forms and will no longer be providing them for builders or heating contractors. Builders should transition to the construction heat program, a transition period will be acknowledged. The TSSA registered Heating Contractor/Installer will ensure 100% compliance as per the TSSA Advisory (FS-232-17).

- Appliance setup and commissioning is the sole responsibility of the TSSA registered Heating Contractor/Installer.
- In a situation where a final inspection reveals that proper set up and commissioning has not taken place, Enbridge will use the Safety Infraction process (sometimes referred to as a B-Tag). What you will see on the Safety Infraction will read “Appliance requires Commissioning as per CSA B149.1 Clause 4.3.1” The builder will require the Heating Contractor/Installer to return to perform the work and clear the Safety Infraction.
- Appliances requiring set up and commissioning as per the manufacturer installation instructions, including Furnaces, Boilers and Combi-Heat/Hot Water units (Hot Water Tanks if noted in the manufacturer instructions)
- Appliance set up and commissioning does not apply to gas appliances (unless noted by the manufacturer instructions), including BBQs, Fireplaces, Ranges and Dryers.
- All furnaces used for construction or finishing heat must be commissioned by the HVAC Contractor prior to the inspection for home owner occupancy.

We will transfer account and gas bills to the new homeowners on the closing date.

Ensuring worker and public safety is our number one priority. Before any demolition work can begin on a property, the natural gas service must be safely disconnected by Enbridge Gas and natural gas lines must be located to avoid damage.

What we will do
- Apply for a permit with the municipality.
- Visit the site to assess the necessary resources and the cost to complete the work.
- Provide a quote for the expected work. Our fee is regulated by the Ontario Energy Board. We require written confirmation that the property owner accepts these charges and consents to the cut off. If we don’t receive confirmation by a specified date, we can’t proceed with the work. At that point, the work request will be terminated.
- Request underground utility locates for the area where we’ll be working.
