Put this into practice

Start with your business

Organize formation, standing, and the records that let the business operate.

Start with your business

If you have just opened a notice and your stomach dropped, start here. This is the short version, and the first thing to know is that people get through this every year, including people with less time left than you have.

Someone else's version of today

"Received a notice today saying it would essentially be illegal for me to work 2 months from now, and it scared the shit out of me. I have my test booked in about 3 weeks, so I have 2 shots to pass it before then."

an apprentice on r/SkilledTradesOntario

And how he got there, which is the ordinary way rather than a careless one:

"So I failed my 309A exam by two points when I came out of school, and then was a lazy pos afterwards. Thinking there was no time limit, I put it off for a few months, and then a few months turned into 7-8 months..."

the same apprentice

Two points. Then seven months, because nothing told him a clock was running. That is the actual failure mode, and it is administrative rather than technical.

Today, in order

1. Find your real date. Not roughly. The date on the certificate. Everything below is measured from it.

2. Book the exam before you study. Booking is the part with the queue in it, and the queue is not yours to control. One person in the corpus waited two months for a booking code. A seat you can move is worth more than a week of revision.

3. Count backwards from the seat, not forwards from today. Sitting the exam is not the finish line, the result is, and results take time to arrive. If your seat is three weeks out and your certificate has eight weeks left, that is the whole picture and it is tight but workable.

4. Tell your employer today, not in the last fortnight. They have seen this before, and in a compulsory trade the exposure is theirs as well as yours. The conversation is much easier at eight weeks than at two.

5. Ask STO, in writing, what your options are if the date passes. Whether a provisional can be extended, how many attempts you get and in what window, and what happens between an expiry and a pass are all things they set and change. Get the answer for your case in writing with a reference number rather than from a forum, including this page. How to get that answer, and how to escalate when nobody gives you one, is dealing with Skilled Trades Ontario.

6. Study the failure, not the trade. People fail this by one or two points, which means the gap is usually narrow and specific: the code book index, one calculation, one section. The Last Mile to C of Q guides are per trade and written for exactly that gap.

Never being here again

The reason this page exists is that the notice arrives too late to be useful. The date was knowable the whole time.

The Licences and credentials panel warning that a 309A Electrician provisional certificate expires on September 22 2026, 48 days away, with the row underneath showing 48d leftThe number that decides whether you can legally keep working, counted down where you will actually see it.

Put the date in once and it counts down in front of you, with a warning window you set. Ninety days is the right setting for a provisional, because ninety days is roughly what a booking plus a seat plus a result actually costs when it goes badly.

That is the whole of the software's part in this. It does not book exams, extend anything, or contact anyone. It makes sure the notice is not the first time you think about it.

Get your dates from STO, in writing

How long your provisional runs, whether it can be extended, how many attempts you have and what each costs are set by regulation and by Skilled Trades Ontario, and they change.

Ask STO directly and get the answer in writing, then put that date somewhere that will warn you. This is your right to work; it is worth one phone call and a written reply rather than a number you half-remember from a forum.

What it costs

Commercial terms depend on the workflow. Review the relevant AEC Stack product page before you start.

See who is hiring

On AEC Stack: if you have the years but not the apprenticeship, the other route is challenging the C of Q on your experience. If it is the sponsorship that is missing, that is finding an employer who will sign you up.

Book the seat today. Then put the date in your dashboard so the next renewal is a diary entry rather than a shock.
