How to Check a Home Modification Contractor: Licences, WSIB and Insurance

Dad's knees have made the stairs a daily negotiation, a stair lift company is booked for Thursday, and you live two hours away. You want to know the people walking into his house are qualified, insured and real. Nobody hands you that list.

In Ontario, there is no single licence for a home modification contractor. Electrical work must be done by a contractor licensed by the Electrical Safety Authority (ESA), plumbing by a tradesperson on the Skilled Trades Ontario Public Register, and a stair lift or home elevator in a private house is exempt from TSSA's elevating device rules. General renovators need no provincial licence, though Toronto requires a City Building Renovator licence.

Do this next:

• Run our free home safety audit first, so you know which jobs you're actually hiring for.
• Compare ranked installers near your parent on our stair lift directory or our accessibility contractors directory.
• Keep the ESA contractor locator open in a second tab while you read quotes.

Does a home modification contractor need a licence in Ontario?

It depends on the trade, not the job title. The licence follows the regulated work (wiring, plumbing), so one bathroom renovation can involve two licensed trades and a renovator who needs none.

Our take: Don't ask "are you licensed?" Ask "which of your trades are licensed, and what are the numbers?" A good contractor answers in one breath.

How do you check an electrician with the ESA?

Look the company up on the ESA's Contractor Locator by name or location, then match the licence number on the quote. ESA is clear that an electrician isn't permitted to do electrical work unless they're employed by a Licensed Electrical Contractor, and that applies even to a single new outlet beside a lift chair.

1. Ask for the company's ECRA/ESA licence number. It belongs on the estimate and on the work vehicle.
2. Search the company on the ESA Contractor Locator. If it isn't there, treat that as a warning.
3. Check the estimate includes the ESA notification fee. The contractor files the notification; you shouldn't be told ESA "doesn't need to be involved."
4. When the work passes, ask for the Certificate of Acceptance. ESA describes it as proof the work meets the Ontario Electrical Safety Code, and it's worth keeping for insurance and resale.

Stuck, or suspicious? ESA's line is 1-877-ESA-SAFE (1-877-372-7233), and unlicensed work can be reported anonymously.

How do you check a plumber on the Skilled Trades Ontario register?

Search the person's name on the Skilled Trades Ontario Public Register. Plumbing is a compulsory trade, so anyone doing it must hold a Certificate of Qualification, a Provisional Certificate of Qualification or a Registered Training Agreement (an apprentice), and must appear on that register.

The register is searched by a person's name or Skilled Trades Ontario ID, not the company name. So ask who will actually be doing the plumbing on your parent's curbless shower, and check that person. An apprentice is fine, as long as a certified plumber is supervising.

The same register covers other compulsory trades, including construction and maintenance electricians, which is a useful second check on the person behind the ESA licence.

Does TSSA license stair lifts and home elevators?

Not in a private house. The Technical Standards and Safety Authority's Am I Regulated? page exempts elevating devices in private dwelling houses used only by the occupants and their guests, unless the owner asks in writing to be covered. A stair lift in Mom's semi sits outside TSSA's inspection and licensing.

That surprises families, because the same lift in a retirement home or condo common area is regulated. Some installers do both kinds of work and hold a TSSA elevating device contractor registration for it. It isn't required for a house, but it tells you the company works to an inspected standard elsewhere.

What to ask for instead:

• The CSA standard the lift is certified to, in writing on the quote.
• Who confirms whether a building permit is needed. Anything that cuts into a floor, a wall or the stairs is a question for the municipal building department, asked before work starts.
• A licensed electrical contractor for any new circuit, per the ESA steps above.
• The maintenance schedule, who services it, and how fast they come when it stops.

Our take: With no inspector in the house, the installer's service record is your safety net. Choose the company that will still pick up the phone in year five, not the one with the lowest install price. Our stair lift cost guide and home elevator cost guide show where the money goes.

Do general renovation contractors need a licence in Ontario?

No provincial licence exists for renovators in Ontario. The Home Construction Regulatory Authority licenses builders and sellers of new homes, not people who renovate existing ones, so a contractor quoting grab bars, a ramp or wider doorways won't have one.

Toronto is the exception families should know. The City says a Building Renovator licence is required for every business that repairs or renovates buildings, and it's issued by Municipal Licensing and Standards. There's no public search tool, so email MLSBusinessLicence@toronto.ca with the business name to confirm.

In Ottawa, Mississauga or Hamilton, check the city's own business licensing page, since rules vary. Then ask the renovator who pulls any building permit. It should be them, in writing, not your parent.

Should you ask for WSIB clearance and insurance?

Yes, even though Ontario doesn't require it for this job. WSIB's clearance FAQ says a clearance certificate isn't required when a home's resident, occupant or a member of their family hires a contractor for home repairs or renovations. That covers you hiring for your parent.

We'd still ask. A clearance is a number showing the business is registered and up to date with WSIB, and a contractor who has one is running a real operation with covered workers. You can check it with WSIB's free clearance search, by business name or postal code.

Then ask for a certificate of commercial general liability insurance, issued by the insurer, not a photo of a policy page. Call the broker on it to confirm it's current.

Our take: A sole operator who is exempt from WSIB can't produce a clearance and may give you a letter instead. That's legitimate. Refusing to show either is not.

How does the Assistive Devices Program work with vendors and authorizers?

For mobility aids, Ontario's Assistive Devices Program (ADP) pays 75% of the approved price through an ADP-registered business, and your parent pays the other 25%. The device has to be recommended first by an occupational therapist or physiotherapist registered with ADP (the authorizer).

On the ADP mobility aids page, the order matters:

1. An ADP-registered therapist assesses your parent and recommends the device. Email adp@ontario.ca to find one locally.
2. An ADP-registered business helps complete the form, submits it and bills ADP directly.
3. The business can't charge more than the ADP price for the approved device.

Buy before the approval and your parent pays the full cost. Also know what ADP won't fund: stair lifts, chair lifts and other lifting devices, and home renovations including ramps and porch lifts. A salesperson implying ADP will cover a stair lift is wrong. Our ADP guide and home accessibility grants guide cover the funding that does apply.

What does a business registration prove, and what doesn't it?

A business registration proves the company legally exists and whether it's active. It says nothing about whether the electrician is licensed, whether the crew is insured or whether the work will be good.

Federal corporations are searchable on Corporations Canada by name, corporation number or business number. Two limits matter. Trade names aren't in that database, so search the legal name on the quote. And companies incorporated provincially aren't there at all; Corporations Canada points you to Canada's Business Registries for those.

Use it as a first filter. A company that's dissolved, or whose legal name doesn't match the contract, is one to pause on.

How do you read the Licenses & Registrations section on a Senior Care Path listing?

Each installer profile has a Licenses & Registrations section with up to two kinds of entry, and they mean different things.

• Registered business card. We matched the listing to Corporations Canada (or Quebec's register) by name plus postal area or city, and a person reviewed the match. It shows the registered name, the corporation number, the status, the month we checked and a link to the official record.
• Licence lines. These come from the provider's own website. They're a useful start, and the note under them says so: confirm current licensing and insurance directly before hiring.

Because no single provincial licence covers aging-in-place work, a verified registration earns the "Licenses & registration verified" points in our SCP Confidence Score for these listings, our 100-point confidence rating. It is one signal of eleven, not a safety certificate.

Membership badges sit separately under Associations & Accreditations. Our guide to senior care associations explains what those memberships do and don't tell you.

What are the red flags when hiring a contractor for a parent's home?

Most bad hires announce themselves early. Walk away from anyone who:

• Can't give an ESA licence number for electrical work, or says ESA doesn't need to know.
• Asks your parent to pull the building permit "to save time."
• Wants cash, or a large deposit before any materials arrive.
• Says ADP or a grant will cover a stair lift or a ramp.
• Has a legal name on the contract that doesn't match the company you searched.
• Pressures your parent to sign the same day, at the kitchen table.

On that last one: in Ontario, a contract over $50 signed with a salesperson in the home can be cancelled within 10 days of receiving the written copy, under the province's door-to-door and home contract rules. Put your number on the contract and ask that nothing be signed while you're not on the call.

Is a premium installer worth paying more for?

Often, yes, for anything with a motor. A higher quote from an established installer usually buys a home visit with an occupational therapist present, a CSA-certified product, a written service plan and a technician within reach of your parent's city. Those are the things that matter when a lift stalls halfway up.

For a grab bar or a handrail, the premium buys less. A careful handyman with insurance, the right anchors and good references is enough, and the money is better spent on the bathroom itself. Our accessible bathroom guide shows where the upper end earns its price.

What about B.C., Alberta and Quebec?

British Columbia: Technical Safety BC says lifts and elevators in private residences aren't regulated by any provincial or municipal authority, and recommends a class H elevating contractor from its Find a Licensed Contractor tool. It also advises three estimates and an OT or physiotherapist at the site visit. WorkSafeBC offers free clearance letters.

Alberta: A contractor who signs contracts away from their own premises and takes money before the work is finished needs a prepaid contracting licence from the province, searchable on Service Alberta's licensed business tool. WCB-Alberta issues clearance letters confirming a contractor's account is in good standing.

Quebec: Contractors need a licence from the Régie du bâtiment du Québec. Enter the licence number in the RBQ's licence holders' register and check that its subclasses match the job.

Once the checks are done, you get to stop being the inspector and go back to being the son or daughter who visits. That's the point of all this.
