How to Find a Reliable Contractor in Toronto in 2026: 10 Checks Before You Hire

Hiring someone to renovate your home can involve tens of thousands of dollars, weeks or months of disruption and giving contractors regular access to your property.

Yet homeowners are often expected to make that decision after little more than a search result, a few reviews and a quote.

There is a better approach.

Toronto and Ontario provide several public tools and consumer protections that homeowners can use before paying a deposit or signing a major renovation contract.

Here are 10 checks worth doing in 2026.

Quick Checklist

Before hiring a Toronto renovation contractor:

1. Verify the City of Toronto Building Renovator licence
2. Search Ontario's Consumer Beware List
3. Get at least three written estimates
4. Check at least three references
5. Confirm building-permit requirements
6. Keep the deposit reasonable
7. Put the entire agreement in writing
8. Verify specialized trades and required coverage
9. Agree on change orders before extra work starts
10. Keep records of every agreement and payment

None of these checks guarantees a perfect renovation.

Together, however, they can make obvious problems much easier to identify before they become expensive ones.

1. Verify the Contractor's Toronto Business Licence

This should be one of the first checks.

Toronto requires a Building Renovator licence for businesses providing services to repair or renovate buildings and structures, including businesses advertising renovation services.

The licensing process includes documentation requirements and a trade examination.

But you do not have to take a contractor's word that they are licensed.

Toronto has a public Business Licence Lookup that lets consumers search using information such as:

• operating name
• licence holder
• corporation
• address
• licence number
• trade number
• licence category

Ask the contractor for the exact name under which the business is licensed and then search it yourself.

Also read any conditions attached to the licence.

Toronto licence records can include conditions limiting the work the business can perform directly or requiring certain work to be subcontracted to appropriately licensed renovators or trades.

A valid City licence does not guarantee excellent workmanship.

But if a business cannot be found where a licence should exist, that deserves further investigation.

2. Search Ontario's Consumer Beware List

Ontario maintains a searchable Consumer Beware List.

The list can include businesses that:

• did not respond after the Ministry contacted them twice about a consumer complaint
• were charged under consumer-protection legislation
• were convicted
• became subject to certain compliance actions

Ontario recommends searching both the business name and the individual operator's name because one person may operate under more than one business name.

A clean search does not prove that a contractor has never had a problem.

Not every customer complaint becomes a public Consumer Beware List entry.

Ontario generally keeps relevant information on the list for roughly 21 to 27 months.

Use it as one background check rather than the entire decision.

3. Get at Least Three Written Estimates

Ontario's current renovation guidance recommends getting at least three written estimates from different contractors.

That is useful for much more than comparing price.

Compare whether each contractor is actually quoting the same scope.

One estimate may include:

• demolition
• disposal
• framing
• electrical work
• plumbing
• finishes
• materials
• permits
• cleanup

while another excludes several of those items.

A dramatically lower quote is not automatically dishonest.

But it should lead to a useful question:

What is missing from this estimate that the others included?

Avoid relying on an estimate given entirely over the phone without the contractor seeing the work.

For a significant project, the estimate should be detailed enough that you understand what you are paying for.

4. Check at Least Three References

Ontario recommends obtaining and checking at least three references, even if the contractor was recommended by someone you know.

The references should ideally come from customers who had work similar to the project you are planning.

Ontario also recommends checking both:

• recent references
• references from further back in time

That matters because some renovation problems do not become visible immediately.

A homeowner whose roof was installed a month ago can tell you about communication and scheduling.

Someone whose roof was installed several years ago can tell you how the work actually held up.

Useful questions include:

• Was the final cost close to the agreed price?
• Was the work completed close to schedule?
• How were unexpected problems handled?
• Did the contractor communicate clearly?
• Were subcontractors properly managed?
• Was the property kept reasonably clean?
• Did problems appear later?
• Did the contractor return to fix deficiencies?
• Would you hire the contractor again?

5. Confirm Whether Building Permits Are Required

Many Toronto renovation projects require building permits.

Permit requirements depend on the work.

Projects involving structural changes, additions, major alterations and other Building Code matters commonly require City approval.

Do not assume:

“The contractor said no permit is needed.”

Toronto specifically warns homeowners that they can still be responsible for consequences when required work begins without a permit, even if a contractor told them one was unnecessary.

Those consequences can include:

• a work-without-permit fee
• delays while an application is reviewed
• a stop to construction
• having to undo completed work
• additional corrective construction
• future problems involving insurance or sale of the property

For 2026, Toronto's work-without-permit administrative charge is generally 50% of the applicable permit fee or $214.79, whichever is greater, up to the City's maximum of $29,456.99 per permit.

If the contractor is responsible for applying for permits, put that responsibility in the contract.

And if a permit is required, do not let the work begin simply because someone says:

“We applied for it.”

Toronto has a public system where homeowners can check active building-permit and inspection status.

6. Keep the Deposit Reasonable

Ontario advises consumers to keep renovation down payments to a minimum and specifically recommends no more than about 10% of the total project cost.

It also advises against paying the entire contract amount before the work is finished.

Deposits can be legitimate.

A contractor may need to:

• reserve project dates
• order custom materials
• secure supplier orders

But a request for a very large payment before meaningful work has started deserves an explanation.

Ask:

“What specifically is this deposit paying for?”

A staged payment schedule tied to clear project milestones can also make it easier to understand what you are paying for as the work progresses.

Avoid undocumented cash payments.

If you pay in cash, get a detailed signed receipt.

7. Put the Entire Agreement in Writing

For a significant renovation, a text-message quote and handshake are not enough.

Ontario says home-renovation contracts worth more than $50 must be in writing.

A proper contract should address matters such as:

• contractor name and contact information
• detailed scope of work
• materials
• warranties
• total price
• payment schedule
• deposit
• start date
• expected completion date
• subcontracted work
• permit responsibility
• cleanup
• how changes will be approved

Make sure the written estimate forms part of the contract.

That matters because Ontario's Consumer Protection Act generally prevents a contractor from charging more than 10% above an estimate included in the contract unless you agree to additional or different work or agree to a new price.

If the project changes substantially, document the change rather than relying on a verbal agreement.

8. Verify Specialized Trades Separately

A general renovation contractor can coordinate many parts of a project.

That does not mean the renovation licence allows that business to personally perform every regulated trade.

Electrical work is a clear example.

In Ontario, electrical work performed for hire must be done through a Licensed Electrical Contractor.

The Electrical Safety Authority provides a public contractor locator that homeowners can use to find or verify the contractor.

ESA also advises homeowners to check the contractor's ECRA/ESA licence number and ensure the appropriate electrical notification is filed.

If a general contractor says:

“My electrician handles that.”

ask:

Who exactly is the electrical contractor?

Then verify them.

Similar due diligence may be appropriate for other regulated or certified trades involved in the project.

Ontario also advises homeowners to consider workplace safety and insurance requirements. Construction workers and independent operators can have WSIB obligations, subject to applicable exceptions.

9. Agree on Change Orders Before Extra Work Starts

Renovations uncover surprises.

A wall comes down and reveals water damage.

Old wiring needs additional work.

The homeowner changes their mind about flooring.

Changes themselves are not necessarily a problem.

The problem is allowing substantial additional work to happen without agreeing to the cost first.

Ontario's current guidance says changes to the work and price should be documented.

A useful written change order should identify:

• what is changing
• why it is changing
• added or reduced cost
• effect on the project schedule
• homeowner approval

Ideally, that agreement happens before the additional work is performed.

This also protects the contractor by creating a clear record of what the homeowner requested.

10. Keep the Paperwork

Keep copies of:

• written estimates
• signed contract
• change orders
• invoices
• receipts
• permit documents
• warranties
• inspection information
• important emails
• relevant text messages
• proof of every payment

Do not assume you will remember what was agreed six months later.

The paperwork may become extremely important if there is a dispute over:

• price
• workmanship
• scope
• warranties
• permits
• completion

Ontario specifically warns consumers about paper-free renovation arrangements.

A written record protects both sides.

What About Online Reviews?

Online reviews can be useful.

They just should not be your only verification method.

Look for recurring patterns involving:

• missed deadlines
• unexplained additional charges
• disappearing after receiving deposits
• unfinished work
• poor communication
• failure to correct deficiencies

But reviews have limitations.

They can be incomplete, manipulated or based on circumstances very different from your project.

Use reviews alongside:

• licence verification
• government records
• references
• estimates
• permits
• written contracts

The combination is more useful than any single star rating.

Renovation Red Flags Worth Investigating

One red flag by itself does not prove that a contractor is dishonest.

Several together should make you cautious.

Examples include:

• pressure to sign immediately
• unusually large upfront payment
• insistence on cash without proper receipts
• refusal to provide a detailed written contract
• refusal to provide references
• no verifiable licence where one should exist
• telling you permits are unnecessary without a clear explanation
• dramatically lower pricing than comparable estimates
• vague answers about subcontractors
• payments requested to unrelated individuals
• repeated requests for money ahead of agreed milestones
• an electrical contractor who cannot provide an ECRA/ESA licence number

Professional contractors should generally expect customers to ask reasonable questions about the project.

Know About Ontario's 10-Day Cooling-Off Period

Ontario provides an important consumer protection for certain contracts signed in a consumer's home.

If you sign a qualifying home-renovation or repair contract worth $50 or more in your home, Ontario says you generally have a 10-calendar-day cooling-off period.

During that period, the contract can generally be cancelled for any reason without a cancellation fee.

If you specifically asked the contractor to begin work during that cooling-off period and then cancel, you may still owe reasonable compensation for work performed and materials already provided that cannot be returned.

The exact rights depend on how and where the agreement was made.

If a serious dispute arises, consult Ontario's current consumer-protection guidance or obtain appropriate legal advice.

Check the Permit Yourself

If a permit is required and the contractor says it has been issued, you can independently check Toronto's public Building Permit Application & Inspection Status system.

That system contains information about many active permits and inspections.

For very large projects, homeowners may also want to understand:

• who is named on the permit
• which inspections are required
• whether inspections have passed
• whether the permit is still open when the project appears finished

A contractor saying:

“The inspector came by.”

is not necessarily the same as confirming that the required inspection was passed.

Find Contractors and Home-Service Businesses in Toronto

Homeowners can discover local renovation and household-service businesses through the AD18 Business Directory.

• Toronto Home Services: Browse Toronto home-service businesses →
• Toronto Business Directory: Browse all Toronto businesses →

An AD18 Directory listing is a discovery tool.

It does not mean AD18 has independently verified a contractor's:

• City licence
• permits
• insurance
• trade qualifications
• references
• workmanship

Homeowners should perform the same checks before hiring a listed business.

The Bottom Line

Finding a reliable Toronto contractor does not require becoming a construction expert.

It requires slowing the decision down enough to verify the basics.

Before hiring:

verify the licence → check government records → compare written estimates → call references → confirm permits → control the deposit → sign a detailed contract → verify specialized trades → document changes → keep your records

No process eliminates every risk.

But those checks give homeowners much more information than choosing someone based only on a search result and a price.

A professional contractor should generally expect reasonable questions about:

• licensing
• permits
• insurance
• subcontractors
• contracts
• payment terms

If basic verification becomes unusually difficult before the project begins, that information is useful too.
