How many quotes should I get from contractors in Ontario?

As a general rule, get at least three quotes for any project of meaningful size. For larger renovations costing tens of thousands of dollars, four or five quotes give you a better picture of the true market rate in your area of the GTA.

Should HST be included in a contractor quote in Ontario?

Ontario's HST is 13% and should be clearly stated in any written quote — either included in the total or itemised separately. Always confirm this before signing anything, as a quote that excludes HST can look deceptively affordable.

What licences should I check when hiring a contractor in the GTA?

It depends on the trade. Electricians must be licensed through the Electrical Safety Authority (ESA), gas technicians through the TSSA, and many skilled trades — such as plumbers and HVAC technicians — must hold Ontario College of Trades (OCOT) certification. Always ask for proof and verify directly with the relevant body if you have any doubt.

Does a contractor in Ontario need to carry WSIB coverage?

Most contractors working in Ontario are required to be registered with the Workplace Safety and Insurance Board (WSIB). Ask for a WSIB clearance certificate before work begins. This protects you from potential liability if a worker is injured on your property.

Is the lowest quote always the best choice when hiring a contractor?

Not necessarily. A low quote may exclude permits, HST, or key materials, or it may reflect unlicensed labour or inadequate insurance. Compare quotes on scope, credentials, warranties, and communication quality — not price alone.

How to Get Multiple Quotes from Contractors in Ontario (2026)

Whether you're replacing your electrical panel in Mississauga, installing a new furnace in Scarborough, or renovating a bathroom in North York, getting multiple quotes from contractors is one of the smartest things you can do as an Ontario homeowner. It's not just about finding the lowest price — it's about understanding what you're paying for, confirming the work is being done legally, and protecting yourself if something goes wrong. This guide walks you through the process clearly and practically.

Why Multiple Quotes Matter in Ontario

In the GTA, labour costs, material pricing, and permit fees can vary considerably from one contractor to the next. A quote that seems low may exclude HST (Ontario's Harmonized Sales Tax at 13%), permit fees, or critical materials. A higher quote might reflect better insurance coverage, licensed tradespeople, and a more thorough scope of work. Without at least two or three quotes side by side, you have no reliable basis for comparison.

Beyond price, gathering multiple quotes gives you the chance to assess how different contractors communicate, how thoroughly they review the job, and whether they hold the proper credentials — such as an Electrical Safety Authority (ESA) licence for electrical work, a Technical Standards and Safety Authority (TSSA) registration for gas work, or Ontario College of Trades (OCOT) certification for regulated trades like plumbing or HVAC.

How Many Quotes Should You Get?

A common and sensible rule of thumb is three quotes minimum for any project over a few hundred dollars. Three quotes give you a meaningful spread: you can identify an outlier on the low end (which often signals corners being cut) and an outlier on the high end, and you gain a clearer sense of a realistic market rate for the work in your area of the GTA.

For larger projects — full kitchen renovations, new roofs, home additions — consider getting four or five quotes. The additional time investment is well worth it when tens of thousands of dollars are at stake.

How to Prepare Before Reaching Out to Contractors

The more specific you are, the more accurate and comparable your quotes will be. Before contacting anyone, prepare the following:

A clear written description of the work — Include dimensions, materials you prefer, and any relevant details about your home (age, existing systems, access issues).
Any existing plans or drawings — If you've had an architect or designer involved, share those documents.
Your timeline — Let contractors know when you'd like the work to start and your target completion date.
Permit awareness — In Ontario, many renovation and trade projects require a building permit from your local municipality, or an ESA or TSSA inspection. Mention this upfront and ask each contractor how they handle permits.

Sending every contractor the same written brief means you're comparing apples to apples, not guessing why two quotes differ by thousands of dollars.

What to Ask Each Contractor

When a contractor visits your home or reviews your project details, use the conversation to gather key information. Ask:

Are you licensed and registered with the relevant Ontario authority (ESA, TSSA, OCOT) for this type of work?
Do you carry liability insurance and WSIB (Workplace Safety and Insurance Board) coverage? Can you provide certificates?
Will you pull the required permits, and is that included in your quote?
Is HST included in this figure, or will it be added?
What is your payment schedule, and do you require a deposit?
Can you provide references from similar projects in the GTA?

A reputable contractor will answer these questions without hesitation. Hesitation or vague answers around licensing and WSIB are red flags worth taking seriously.

How to Compare Quotes Fairly

Once your quotes are in hand, resist the urge to jump straight to the bottom-line number. Instead, review each quote for:

Scope of work — Does each quote cover exactly the same tasks and materials? If one is significantly cheaper, find out what it excludes.
Materials specified — Brand names, grades, and warranties on materials can differ meaningfully in value.
HST and permits — Confirm whether these are included or listed as extras.
Warranty — What workmanship warranty does each contractor offer after completion?
Timeline and availability — A contractor available immediately is not automatically better than one who is booked a few weeks out. Busy tradespeople are often busy for good reason.

Red Flags to Watch For

In the GTA market, a few warning signs are worth keeping front of mind:

Quotes provided verbally only, with no written breakdown
Requests for large cash deposits or full payment upfront
No mention of permits when permits are clearly required
Inability or unwillingness to provide WSIB clearance certificates
No verifiable business address or contact information beyond a mobile number

Use a Verified Platform to Simplify the Process

One of the most reliable ways to streamline quote-gathering in the GTA is to use a platform that pre-screens contractors against Ontario licensing and compliance requirements. When every contractor in a marketplace has already been verified against ESA, TSSA, OCOT, and WSIB standards, you can focus your energy on comparing scope, price, and fit — rather than spending hours trying to verify credentials on your own. VerifiedPros does exactly this, connecting Ontario homeowners with licensed, vetted trades professionals across the Greater Toronto Area.

Getting multiple quotes isn't a sign of distrust — it's a sign of a diligent homeowner. Take the time to do it properly, and you'll be far more confident in whoever you hire.
