General Contractor Licence Ontario (2026)

Do You Need a General Contractor Licence in Ontario?

Short answer: there is no single provincial "general contractor licence" in Ontario for most work. What you need depends on two questions. Are you building new homes or renovating existing ones? And which city are you working in?

If you renovate existing homes, Ontario does not require a provincial licence. But Toronto, Hamilton, Mississauga, and other cities each run their own contractor licensing programs, and some are mandatory to even advertise your services. If you build or sell new homes, the Home Construction Regulatory Authority (HCRA) does require a licence, and working without one is illegal.

This post breaks down every licence, certification, and registration a general contractor in Ontario needs in 2026, with current fees and links to the official sources.

The provincial licence: HCRA for new home builders only

The Home Construction Regulatory Authority licenses every person or company who builds or sells new homes in Ontario. Per the official HCRA guidance: "In Ontario, all new home builders and sellers are required by law to be licensed by the Home Construction Regulatory Authority (HCRA). It is illegal to build or sell a new home without a valid licence."

Three licence categories exist:

Builder licence: you build new homes
Vendor licence: you sell new homes
Builder/Vendor licence: you do both

Current HCRA fees (from the HCRA licensing fees page):

Item	Fee
New standalone licence (no prior licensing history)	$3,525 one-time
Umbrella licence (tied to a related company)	$880 one-time
Annual renewal	$715
Late renewal penalty	$705 additional
Regulatory oversight	$170 per home built (plus HST)

HCRA licensing typically takes around eight weeks to process once your application is complete. You must apply through the HCRA Builder Portal.

HCRA plus Tarion

An HCRA licence is only half of what new home builders need. You must also apply to Tarion for Qualification for Enrolment (QFE) on every project you build. Tarion handles the statutory new home warranty. QFE can start while your HCRA licence application is in progress, but Tarion will not finalize anything until HCRA issues your licence.

Who is exempt from HCRA licensing

Renovation contractors: "Typically, renovations or upgrades to an existing home do not make the home 'new' and as such, do not require the builder to be licensed."
Owner-builders: a person building a home for their own use on land they own may not need a licence, provided they do not sell the home after construction.
Commercial and industrial builders: HCRA only regulates new residential.

Coach houses, laneway houses, and tiny homes generally do require HCRA licensing and Tarion coverage. Seasonal homes typically do not.

If you renovate, Ontario does not require a provincial licence

For renovations, additions, and repairs to existing homes, there is no Ontario government licence for the general contractor role itself. This confuses a lot of people because every other province treats "general contractor" differently, and because municipalities in Ontario fill the gap.

The rule of thumb: if you are working on an existing building that has been occupied, your provincial obligations are WSIB, HST, insurance, and compulsory trade certifications for specific work. The business licence side of things lives at the municipal level.

Municipal contractor licences: where things get real

This is where most contractors get tripped up. Ontario cities run their own licensing regimes and the rules are not consistent between municipalities.

Toronto Building Renovator licence (mandatory)

If you work in Toronto as a general contractor doing renovations, repairs, or alterations, you need a Building Renovator licence from the city. Per the City of Toronto Building Renovators page, a Building Renovator licence is required for "all businesses that provide services to repair or renovate buildings and structures, including any business that advertises renovation services."

Current Toronto fees:

Item	Fee
Application fee (non-refundable)	$234.62
Licence fee	$260.50
Total new licence cost	$495.12
Trade Exam fee	$79.65 (GST included)
Annual renewal	$293.14

Applicants must pass an oral trade exam (about 30 minutes, in English, interpreters permitted) covering three sections: business acumen, bylaw knowledge, and technical trade knowledge.

Required documents include provincial business name registration, Operating Information Questionnaire, Health and Safety Declaration, applicant photo, and criminal background check. Corporations also need articles of incorporation, officer IDs, and an annual return.

Operating in Toronto without this licence while advertising renovation services is a bylaw violation.

Hamilton trade licence

Under Hamilton Licensing By-law No. 07-170, tradespeople and contractors in certain categories must hold a trade licence with the City of Hamilton. The specific categories and fees are listed on the City of Hamilton trade licence page.

Mississauga trade business licence

Mississauga requires a trade business operating licence. Applicants must provide a Certificate of Insurance with a minimum of $2 million construction liability coverage, and a Certificate of Qualification from Skilled Trades Ontario where applicable. Full details are on the Mississauga trade business licensing page.

Ottawa and other municipalities

Ottawa runs a general business licensing program rather than a mandatory trade-specific licence, with a separate Rental Renovation Licence By-law in the final recommendation stage for spring 2026. Other GTA cities (Vaughan, Brampton, Markham, Richmond Hill) each have their own rules. Always check with the municipality where you will actually work. If you run jobs across several cities, you may need multiple licences.

Compulsory trades: the certifications people confuse with a GC licence

Separate from municipal business licensing, Ontario has 23 compulsory trades. If you personally do the work in one of these trades, you must hold a Certificate of Qualification or Provisional Certificate of Qualification from Skilled Trades Ontario. This is enforced under O. Reg. 876/21, with penalties under O. Reg. 872/21. See Ontario.ca on compulsory trades and enforcement.

The compulsory trades a general contractor will most often bump into:

Electrician (construction and maintenance)
Electrician (domestic and rural)
Plumber
Sheet metal worker
Refrigeration and air conditioning systems mechanic
Steamfitter
Gas technician (regulated separately by TSSA, not Skilled Trades Ontario)

You can still be a general contractor without holding any of these certifications. What you cannot do is personally perform compulsory trade work without the cert. If your GC business includes in-house electrical or plumbing labour, that person must be certified. If you subcontract, the subtrade must be certified.

Electrical work has an additional layer: the contractor company itself must hold an ECRA/ESA Licensed Electrical Contractor licence, which requires a Master Electrician and $2 million in public liability insurance.

Other mandatory registrations for every Ontario GC

Regardless of where you work or what you build, these are non-negotiable.

WSIB registration. If you have employees or if you work in construction at all (even solo), you almost certainly need to register with the Workplace Safety and Insurance Board. Construction-related businesses have mandatory WSIB coverage under the Mandatory Coverage in Construction program. Clients will ask for a WSIB clearance certificate before letting you on site. See the companion guide on WSIB clearance certificates in Ontario for the full process.

HST registration. Once your revenue crosses $30,000 in any 12-month rolling window, CRA requires you to register for an HST number and charge 13 percent on your Ontario invoices. Voluntary registration below $30K is common because it lets you claim input tax credits.

Provincial business name registration. Required for sole proprietors and partnerships operating under any name other than the owner's legal name. Corporations register federally or provincially during incorporation.

Liability insurance. There is no provincial minimum for general contracting, but practical minimums are $2 million for residential and $5 million for commercial work. Most cities and most clients will refuse to let you on site without it.

What to actually do if you are starting a GC business in Ontario

The practical checklist in order:

Decide your scope: new home construction, renovation, or commercial. The licensing path changes drastically.
Register your business name provincially (or incorporate).
Register with WSIB and request your clearance certificate.
Register for HST once you cross $30K (or earlier if you want input tax credits).
Get liability insurance: $2M residential minimum, $5M commercial.
Apply for the municipal licence in each city where you will advertise or work (Toronto Building Renovator is the big one).
If you build new homes: apply to HCRA and enrol with Tarion.
If you do compulsory trade work yourself: get your Certificate of Qualification from Skilled Trades Ontario.
If you do electrical work as a company: get an ECRA/ESA Licensed Electrical Contractor licence.

Skip any of these and you either cannot work legally, cannot get on site, or cannot get paid.
