Gas & Compliance Services Toronto: Enbridge Red Tag, Gas Line Installation & Fireplace

An Enbridge Red Tag is a formal safety notice issued when a gas appliance operates outside code or presents a hazard. Type A tags mean immediate gas shut-off (active leak, cracked heat exchanger, CO leak, venting failure). Type B tags mean a 30-45 day compliance window for corrective work. Our target response is 2 hours across the GTA for Type A calls, and we book Type B compliance inspections typically within 48 hours to leave buffer time. Most Type A tags are cleared and gas restored within 24 hours when the corrective work is completed before 3 PM.

Gas line installation pricing scales with run length, pipe diameter, appliance count, and access difficulty. Short runs under 20 feet with no wall penetration land $400-$800 including permit and pressure test. Medium runs 20-50 feet with wall/ceiling work run $600-$1,500. Long runs 50-100 feet through finished space run $1,200-$2,500. BBQ hookups typically $500-$1,500. Generator gas hookups $800-$3,500. Every job includes TSSA-permitted pressure test and inspection sign-off filed on your behalf.

A cracked heat exchanger is the highest-consequence Enbridge Red Tag trigger because it allows carbon monoxide to leak into the return-air stream where it circulates through the home. Verification requires two diagnostic steps: visual inspection with a borescope camera into each cell of the heat exchanger, and combustion analysis with a calibrated combustion analyzer measuring CO PPM readings in the supply air stream. Any CO reading above roughly 100 PPM in the supply air, or a spike when the blower engages, is diagnostic of a cracked heat exchanger. The furnace is condemned and replaced - never patched.

Yes. Every natural gas line installation in Ontario requires a TSSA-registered contractor and a permit filed before work begins. That includes BBQ, fire table, generator, fireplace, stove, dryer, and any other appliance hookup. Homeowners cannot legally install gas piping themselves in Ontario. The TSSA G2 certification is required for appliances up to 400,000 BTU/hr; G1 for larger or commercial work. We pull permits, complete the pressure test to 1.5x operating pressure, and file the inspection sign-off with TSSA as part of every job.

Yes. A certified second opinion from an independent G1 or G2 technician is your first step. Common dispute grounds include: the original diagnosis was performed without a borescope inspection or combustion analyzer, the technician was not properly certified for the appliance type, or the fault claimed does not match physical evidence. About one in six second-opinion calls we run results in a legitimate dispute where the tag can be overturned. Our second-opinion service is a flat diagnostic fee that applies to any corrective work if the tag is confirmed.

Direct-vent (sealed combustion, exterior vent through side wall), B-vent (draws combustion air from room, vents up chimney), and ventless (limited use in Ontario due to CO regulations, primarily used in outdoor spaces or as decorative log sets). We also convert wood-burning fireplaces to gas by installing an insert with new gas line, direct-vent flue liner, and safety controls. Typical installations run $2,500-$6,000 including venting, gas line to appliance, permit, TSSA pressure test, and mandatory carbon monoxide detector installation per Ontario Regulation 215/01.

Cracked heat exchanger tags require the furnace to be replaced rather than repaired. We typically stage the swap within 24-48 hours to minimise gas service loss. If the outdoor temperature is below zero and the replacement will take longer than 24 hours, we dispatch temporary electric heaters at no cost to keep the home warm. New furnace installations carry the applicable manufacturer parts warranty plus manufacturer parts warranty (typically 5-10 years, up to 20 years on heat exchangers for premium units). Rebate paperwork for HRS is filed on your behalf.
