309A

The 309A is the Ontario Certificate of Qualification for Electrician, Construction and Maintenance, issued by Skilled Trades Ontario. It is a compulsory trade: in Skilled Trades Ontario's own words, to practise it legally in Ontario a person must hold a Registered Training Agreement, a Provisional Certificate of Qualification or a Certificate of Qualification. It authorises the electrical work on a fire alarm system, including the raceway, cable and device wiring. It does not by itself satisfy the Ontario Fire Code qualification for testing, inspecting or altering a system already in service, and it does not let you sell electrical work.

What it is

Trade code 309A, Electrician, Construction and Maintenance. Skilled Trades Ontario issues the Certificate of Qualification and lists the trade as compulsory. Its wording is the whole point: "to practice this trade legally in Ontario a person must hold a Registered Training Agreement, Provisional Certificate of Qualification or Certificate of Qualification." Three legal ways to be on the tools, and no fourth. The trade carries a Red Seal endorsement and aligns nationally under the title Construction Electrician.

What it takes

9,000 hours: 8,160 on the job and 840 in school, delivered as three levels of theoretical instruction, roughly five years. You earn a wage throughout, which is a different financial shape from a certification you buy.

The published in school content explicitly includes fire alarm and building systems, alongside high voltage and control systems. That is where a great deal of confusion in this trade begins. Your schooling really does touch fire alarm, and it still does not qualify you under the Fire Code. Whether the hours you spend on fire alarm count toward the apprenticeship is a separate question, answered in does fire alarm work count toward your 309A hours.

What it costs to get and hold

Checked on Skilled Trades Ontario's own pages, 5 September 2026:

  • Certifying exam: $150 plus HST per attempt. If you complete your apprenticeship in Ontario from 1 January 2025 onward, the first attempt is waived automatically. Fail and there is a 30 day wait, and you pay the fee again.
  • Annual fee: $60 plus HST for journeypersons in compulsory trades.
  • In school tuition is charged by the delivering college, in the region of $400 to $650 per level plus ancillary fees at one Ontario college checked in September 2026. Confirm with yours.

What the 309A authorises

The electrical work. On a fire alarm job that is the raceway, the cable and the device wiring, installed to CAN/ULC-S524 where Building Code Article 3.2.4.5(1) requires it. Nobody without a Registered Training Agreement, a Provisional Certificate of Qualification or the Certificate itself may legally do that work in Ontario.

What it does not authorise

Selling the work. The certificate says you are qualified. It does not let you offer electrical installation services to the public. That takes an ECRA/ESA licence from the Electrical Safety Authority, which in turn requires you to be or employ a Master Electrician.

Fire Code work on a system in service. Ontario Fire Code Division C, Article 1.2.1.2(1)(a) requires anyone performing annual tests or inspections, interconnection testing, or repairs, replacements and alterations to have completed a program or course acceptable to the Fire Marshal. A 309A is not one of them, and holding one grants no exemption. The two accepted programs are run by CFAA and by ECAO as Certi-Fire.

So swapping a failed smoke detector on a live system is captured by the Fire Code even though it is also electrical work. One small job, two credentials.

The advantage the 309A does give you

CFAA states that a licensed Canadian electrician may be exempt from Courses 2, 3 and 4 of its program, worth roughly $1,219, on a $75 processing fee. Certi-Fire's published entry requirement is a licensed electrician or an apprentice with basic electrical knowledge. Both fire alarm routes are built on the assumption that you already hold the trade ticket, which is a strong argument for doing the apprenticeship first and the fire alarm credential second.

The split between the two is in 309A or CFAA, what each one authorises, and the full Ontario picture in who can legally work on fire alarms in Ontario.
