How long does clearing a red tag usually take?
It depends on one thing: what has to change for the appliance to pass. Corrections that stay inside a gas technician's scope and use common parts are fast. Corrections that depend on someone else's schedule or a manufacturer's stock are not.
| Bucket | Typical timeline | Examples |
|---|---|---|
| Single visit | Same appointment, including verification | Leaking connector or flare, missing drip leg, unsupported gas line, unclamped damper, common thermocouple or pressure switch |
| Parts wait | One day to about a week | Gas valve, control board, inducer motor, model-specific fireplace glass or gasket, low-water cutoff |
| Another trade involved | One to three weeks | Chimney liner, electrical circuit for a power vent, masonry repair, structural work for clearances |
| Appliance replacement | Several days to three weeks | Cracked heat exchanger, unavailable parts on an older unit, boiler replacement |
What makes a red tag take longer than it should?
Most delays are not technical. They come from scope, parts, or nobody owning the sequence.
- The correction crosses trades. The gas work is quick; waiting for the chimney or electrical contractor is not.
- Parts on an older appliance. Discontinued boards, valves, and inducers take days to source and are sometimes gone entirely.
- Nobody is managing the sequence. Three contractors each waiting on another is the single most common reason a two-day job becomes a three-week job.
- Access. A tenant-occupied unit, a locked mechanical room, or a condo requiring building approval before work starts.
- The diagnosis changes once the appliance is opened. What the tag cites and what caused it are not always the same thing.
- Approval delay. On a rental or an estate, the person paying is often not the person standing in the mechanical room.
Does a Type B expiry date change the timeline?
It sets your deadline, not your pace. A Type B tag lets the appliance keep running until the date printed on it, after which the utility is notified and gas service to that appliance is suspended. The deadline applies to the correction being completed and verified — not to booking the appointment.
Leave room. If your correction turns out to need an ordered part or a second trade, a date that looked comfortable stops being comfortable fast. And a Type B condition can deteriorate into a Type A situation in the meantime, which is why running one to the last day is a bad plan.
How do I make it go faster?
Front-load the information. Most of the first day of a red tag job is spent finding out things you could have supplied before anyone arrived.
- Photograph the tag front and back before anyone touches it, and send it with your first message.
- Photograph the appliance rating plate — make, model, serial. Parts sourcing starts and stalls there.
- Photograph the venting, the mechanical room, and the outdoor termination. Clearance and venting findings are assessed from these.
- Ask for a diagnosis and a written scope, not just a price, so you know on day one whether another trade is involved.
- Confirm access up front: who unlocks the room, whether a tenant needs notice, whether the condo needs approval.
- Get any non-gas trade booked at the same time as the gas work, not after it, so the verification happens once.
What is happening on the day the tag is cleared?
The correction and the verification are two separate things, and both have to happen before the appliance goes back in service. Verification is specific to the work: repaired piping is pressure-tested and leak-checked, venting and combustion work is confirmed with a spillage test and combustion readings under operating conditions, and control replacements are proven through a full start-up and shutdown cycle.
Then the appliance is returned to service and the tag is cleared. Ask for written confirmation stating which tag it relates to, what defect was corrected, and what tests were performed, and keep it with the tag photo.
How we handle it
A TSSA-certified G1 technician reads your tag and tells you which bucket you are in before the work starts, including whether another trade is involved. What is in scope gets corrected on site. What is not gets scheduled with vetted specialists and managed in sequence until the appliance is verified and the tag is cleared.
Send photos of your tag and we will give you a realistic timeline. If your gas is already off, start with emergency red tag response.
Frequently asked questions
How long does it take to clear a red tag in Ontario?
It depends on the finding. A correction using parts on the truck is often done and verified in a single visit. A correction needing an ordered part typically runs one to several days. A correction requiring another trade, such as a chimney liner or an electrical circuit, or a full appliance replacement, usually runs one to three weeks.
Can a red tag be cleared the same day?
Yes, when the cited defect is inside a gas technician's scope and the parts are on hand — a leaking connector, a missing drip leg, an unsupported line, or a common control. The correction and its verification both have to be completed before the appliance is returned to service, and both can happen in one visit.
What happens if I miss the date on my Type B tag?
A Type B tag allows the appliance to run until the printed date, after which the utility is notified and gas service to that appliance is suspended. Go by the date on your own tag, and treat it as the deadline for the correction being completed and verified rather than for booking the work.
Why is my red tag taking weeks to clear?
Almost always parts, another trade, or an unmanaged sequence. Discontinued components on older appliances can take days to source, chimney and electrical work runs on someone else's schedule, and contractors each waiting on one another is the most common cause of a two-day job turning into a three-week one.
