How much time is left on your tag?
Enter the date written on your tag and the correction period it gives you. Most Type B tags in Ontario allow 90 days, but check the tag — the number on it is the one that counts.
Work out your deadline
When the deadline passes, nothing happens on its own — the defect is still there and the file is still open. An inspector or the utility can return, escalate the tag to Type A and lock the meter, which adds a utility attendance to your schedule before heat comes back.
Insurers can also treat a known, uncorrected gas defect as grounds to deny a claim. A red tag is written evidence that you were told.
The deadline printed on your tag always governs. This is a planning aid only. Red Tag Relief is not affiliated with Enbridge Gas or the Technical Standards and Safety Authority.
What happens when a Type B deadline passes?
Nothing happens automatically, and that is what catches people out. The defect is still there, the tag is still on record, and the file is still open.
An inspector or the utility can return. When they do and the defect has not been corrected, the tag can be escalated to Type A, which means the gas is shut off and the meter can be locked. Getting service restored after a lock is slower than correcting the defect was, because it adds a utility attendance to the schedule.
There is an insurance dimension as well. A known, documented, uncorrected gas defect is the kind of thing an insurer can point to when denying a claim, particularly on a fire or carbon monoxide loss. A red tag is written evidence that you were told.
If you are selling, a passed deadline is worse than an open tag. It shows in the paperwork as a known defect that was left, and it lands in the middle of the closing.
What should you do before the deadline?
Book the correction early rather than at the edge of the window. Parts availability is the usual reason a straightforward job runs past a deadline, and a heat exchanger or a chimney liner is not something anyone stocks on a truck.
Send photos of the tag, the appliance data plate and the venting before anyone attends. That is what turns a two-visit repair into one, and it is the difference between comfortably inside the deadline and arguing about it afterwards.
- Photograph the tag before anything else. It is the only record of what you were tagged for.
- Read the correction period off the tag and put the deadline date in your calendar.
- Book the diagnosis in the first third of the window, not the last.
- If parts are needed, get the order placed at the diagnosis visit.
- Keep the written correction record once the tag is cleared.
Frequently asked questions
How long is a Type B red tag deadline in Ontario?
Commonly 90 days, but the period is written on the tag and that is the one that applies. Some corrections are given shorter windows depending on the defect.
What happens if I miss the correction deadline?
The defect remains and the file stays open. An inspector or the utility can return, escalate the tag to Type A, and lock the meter. Insurers can also treat a known uncorrected gas defect as grounds to deny a claim.
Can I use my furnace while a Type B tag is open?
Usually yes. A Type B tag is issued when the condition is non-compliant but not an immediate hazard. If the technician had found an immediate hazard, the tag would be Type A and the gas would already be off.
Is this calculator official?
No. It is a planning aid. The deadline printed on your tag governs, and Red Tag Relief is not affiliated with Enbridge Gas or the TSSA.
