An Ontario electrical business carries a regulatory cost base that most trades do not. You need an ECRA/ESA electrical contractor licence to bid on, advertise or perform electrical work for others, you need a Master Electrician on staff at all times, you must carry at least $2,000,000 in liability insurance to hold the licence, and you file a notification of work with the Electrical Safety Authority before almost every job. Those are fixed and recurring costs that have to be recovered through your hourly rate, and per-job costs that have to be handled consistently in your books.
Get the recovery wrong and a busy electrical contractor works all year at someone else's margin.
The recurring regulatory costs, as at July 2026
Item | Cost |
Electrical Contractor (EC) licence, annual | $448 |
Master Electrician (ME) licence, annual | $91 |
ME exam | $164 |
Liability insurance required to hold the EC licence | Minimum $2,000,000 coverage |
ESA inspection notification, residential minimum | $92 |
Single family dwelling up to 7,000 sq ft, 0 to 200A | $253 |
Additions or alterations, 1 to 10 outlets | $46 |
Additions or alterations, 11 to 30 outlets | $92 |
Pool installation | $168 |
Skilled Trades Ontario certificate renewal, annual | $60 plus HST |
ESA reprices every April 1, so these are current figures with a shelf life. All are deductible business expenses. What matters is whether they are in your rate.
Two licences, and only one of them lets you contract
This distinction costs people work.
The Electrical Contractor (EC) licence is held by the business. It is what allows you to bid on, advertise or perform electrical work for others
The Master Electrician (ME) licence is held by an individual
Holding an ME licence alone does not let you contract. To get an EC licence the business must be, or continuously employ, at least one Master Electrician as the Designated Master Electrician, hold an Ontario address for service, carry at least $2,000,000 in public liability and property damage insurance, be WSIB registered where required, be current with the Ministry of Finance and CRA, and owe ESA nothing.
A Designated Master Electrician cannot act for more than one contractor at a time. If your DME is an employee rather than an owner, that is a single point of failure in your business worth thinking about, and it has a value that should be reflected in what you pay them.
Both licences are issued by ESA under Ontario Regulation 570/05, made under the Electricity Act.
The 442A myth
Electrician, Construction and Maintenance (309A) is a compulsory trade. Electrician, Domestic and Rural (309C) is compulsory. Industrial Electrician (442A) is not.
This gets stated backwards constantly, including on trade sites and by accountants who have not checked. For 309A and 309C, a person cannot legally work in the trade without a Certificate of Qualification, a Provisional Certificate of Qualification, or a Registered Training Agreement, with their details on the Skilled Trades Ontario public register. A 442A certificate does not have to be renewed because the trade is non-compulsory.
Practically this means your 309A staff carry an annual renewal cost of $60 plus HST and a hard legal requirement, and your 442A staff do not.
Notification fees: the pass-through decision nobody makes deliberately
Almost all electrical work requires a notification of work filed with ESA before work starts. As the Licensed Electrical Contractor you file it, ESA inspects, and on passing issues a Certificate of Acceptance.
You pay ESA when you file. How that reaches the customer is your commercial decision, and both approaches are defensible:
Built into the quoted price. Simpler for the customer, and the cost sits in your cost of sales where it belongs
A separate pass-through line on the invoice. Transparent, and useful where scope is uncertain
What causes trouble is doing both inconsistently, or coding recovered notification fees to revenue while the ESA cost sits in an overhead account. That inflates revenue and understates job cost, and your gross margin percentage stops meaning anything.
Two operational notes with financial consequences. Residential notifications are valid 12 months and expire if no inspection happens, and resubmitting means paying the full inspection fee again. And ESA charges higher non-contractor rates to homeowners filing directly, which is a genuine value argument you can make when a customer suggests pulling their own permit.
Where an electrical contractor's margin leaks
Service calls quoted flat. A flat diagnostic covering travel, a panel inspection and a return trip is a subsidy
Notification fees not recovered on small jobs. A $46 fee on a $300 job is 15% of the invoice
Materials at cost. Wire, breakers and devices carry handling, waste, returns and financing. Cost-plus-nothing is a loss
Apprentice hours billed at journeyperson output. Charging out an apprentice at a rate that assumes journeyperson productivity
Expired notifications. Paying ESA twice for the same job because the inspection never got scheduled
Unwritten change orders. Still the largest single source of unbilled labour in residential trades
Apprentices are unusually valuable here
Electrical apprenticeships are long, and the federal Apprenticeship Job Creation Tax Credit is worth 10% of eligible wages to a maximum of $2,000 per apprentice per year, for the first two years of a registered apprenticeship in a Red Seal trade. Electrician qualifies.
Two things to get right:
Ontario's own apprenticeship credit was eliminated. Only the federal AJCTC exists. Advice suggesting otherwise is out of date.
Buy the tools, do not fund them. If the business buys tools, it is a deductible expense and no benefit to the apprentice. Hand them cash or a tool allowance and it becomes a taxable benefit on their T4, with income tax and CPP withheld. Same money out, worse result. Safety gear is treated more favourably: employer-provided protective clothing, footwear and glasses are not a taxable benefit.
What a service van should be classified as
An electrical service van kitted out with racking and stock is almost always a motor vehicle rather than a passenger vehicle, which means the full cost goes in Class 10 at 30% with no ceiling, rather than being capped at $39,000 in Class 10.1.
A van seating one to three needs more than 50% use transporting goods and equipment to earn income. A crew-cab pickup seating four to nine needs 90%. Worth knowing before you buy the vehicle rather than after.
Frequently asked questions
Do I need an ESA licence to run an electrical business in Ontario?
Yes. An Electrical Contractor licence issued by ECRA/ESA is required to bid on, advertise or perform electrical work for others. A Master Electrician licence alone does not permit you to contract.
How much does an electrical contractor licence cost in Ontario?
As at July 2026, the annual Electrical Contractor licence is $448 and the Master Electrician licence is $91. ESA reprices its fees each April 1.
Is Industrial Electrician 442A a compulsory trade in Ontario?
No. Electrician Construction and Maintenance (309A) and Electrician Domestic and Rural (309C) are compulsory. 442A Industrial Electrician is non-compulsory, and its certificate does not require renewal.
How much is an ESA notification of work?
It varies with the job. As at July 2026 the residential minimum is $92, a single family dwelling up to 7,000 square feet at 0 to 200A is $253, and additions of 1 to 10 outlets are $46. Homeowners filing directly pay higher non-contractor rates.
Should I bill ESA permit fees separately or include them in my price?
Either works, but be consistent. Problems come from recording recovered fees as revenue while the ESA cost sits in overhead, which inflates revenue and understates job cost so your gross margin stops being meaningful.
How long is an ESA residential notification valid?
Twelve months. If no inspection takes place it expires, and resubmitting means paying the full inspection fee again.
What tax credit is available for hiring an electrical apprentice?
The federal Apprenticeship Job Creation Tax Credit, worth 10% of eligible wages to a maximum of $2,000 per apprentice per year for the first two years of a registered apprenticeship in a Red Seal trade. Ontario's own apprenticeship credit was eliminated.
What CCA class does an electrician's service van go in?
Class 10 at 30% with no cost ceiling, if it qualifies as a motor vehicle. A van seating one to three used more than 50% to transport goods and equipment qualifies, avoiding the $39,000 passenger vehicle cap.

The EC licence belongs to the business, the ME licence to a person, and only the EC licence lets you contract
Annual regulatory base as at July 2026: EC $448, ME $91, plus $2,000,000 minimum liability coverage and $60 plus HST per compulsory certificate
309A and 309C are compulsory. 442A is not, despite what most sources say
Notification fees are real per-job costs. Recover them and code them consistently
Residential notifications expire after 12 months and you pay again
The federal AJCTC is worth up to $2,000 per apprentice. The Ontario credit is gone
