Labour-Only Renovation Contracts in Ontario (2026 Guide)
More Hamilton and Burlington homeowners are coming to us with materials already in hand — tile from a RONA sale, cabinets from IKEA, or engineered hardwood found on Facebook Marketplace. A labour-only renovation contract is a common arrangement for situations like this, but it works differently from a standard supply-and-install agreement. Before you sign anything, there are a few things every Ontario homeowner should understand.
What Is a Labour-Only Renovation Contract?
A labour-only contract means the contractor supplies their time, tools, and expertise — but not the materials. You, the homeowner, source and purchase all the products: tile, fixtures, lumber, hardware. The contractor installs what you provide.
This differs from a standard renovation contract where the contractor marks up materials and takes responsibility for sourcing and coordinating deliveries. Under a labour-only arrangement, material responsibility sits entirely with you.
Ontario’s Consumer Protection Act, 2002 still applies regardless of the contract type. Even in labour-only deals, any renovation contract over $50 must be written and signed, and you have the right to cancel within 10 days of receiving your copy.
When Does a Labour-Only Contract Make Sense?
We see labour-only arrangements work well in specific situations:
- You’ve already purchased materials — maybe you scored a great deal or received product as part of an insurance settlement
- You have trade-specific knowledge — some clients work in construction and know exactly what they need and how to spec it
- You’re renovating a rental property and want tighter control over material costs
- The scope is narrow and well-defined — like tiling a single bathroom or installing pre-finished hardwood throughout a main floor
For larger projects — full kitchen renovations, basement finishes, or anything requiring structural work — we typically recommend a full supply-and-install contract. Coordinating materials across multiple trades is complex, and gaps in that coordination usually cost more to fix than the material savings were worth.
Key Terms Every Labour-Only Contract Should Include
Whether you’re working with MTC Renovations or any other contractor in the Hamilton area, your written contract should cover these specifics:
Scope of work: A detailed description of exactly what the contractor will and won’t do. If you’re supplying IKEA cabinets, the scope should specify assembly, levelling, shimming, and installation — not just “cabinet install.”
Material responsibility clause: This spells out what happens if the materials you supply are defective, short in quantity, or the wrong spec. Most contractors won’t warranty workmanship on materials they didn’t supply. If you under-order tile and run short mid-job, the cost of a return trip is on you.
Statutory holdback: Under Ontario’s Construction Act, a 10% holdback applies to all construction contracts. This protects workers and suppliers from non-payment. Even in labour-only contracts, this requirement applies. Your contract should acknowledge it.
Payment schedule: Avoid any contract that demands full payment upfront. A typical structure is 10–20% on signing, progress payments tied to milestones, and a final payment on completion and your walkthrough.
Lien release: When you make final payment, ask for a signed statutory declaration confirming all workers and sub-trades have been paid. This protects you from Construction Act liens being registered against your property title after the fact.
HST and Labour-Only Contracts in Ontario
This is the point that surprises most homeowners: HST still applies to the labour portion of a renovation, even when you supply the materials yourself. The CRA classifies renovation services as a taxable supply, so your contractor will charge 13% HST on their labour invoice regardless.
The good news is you don’t pay HST twice on materials — you already paid it at purchase. But make sure your contractor is HST-registered and includes their HST registration number on every invoice. This matters if you later claim programs like the Ontario New Housing Rebate or need to document costs for a sale.
A legitimate contractor will never suggest keeping the work “off the books” to avoid tax. If someone proposes that, walk away. Participating in an off-the-books transaction can expose you to CRA liability as well.
Risks of Labour-Only Agreements — and How to Reduce Them
The biggest risk in labour-only contracts is the grey zone around responsibility when things go wrong.
Imagine you purchase porcelain tile from a liquidation sale — great price, but a few boxes turn out to be from a different production batch with a slight colour shift. Once it’s installed, you notice. The contractor installed it correctly per the spec you provided. The look isn’t what you expected. Who’s responsible? You are, because you sourced the material.
Situations like this happen more than you’d think. To protect yourself:
- Order 10–15% extra material to account for cuts, breakage, and future patch repairs
- Inspect all materials before the job starts — confirm quantities, colours, and product codes with your contractor before anyone touches anything
- Confirm compatibility — some flooring products require specific underlayment; some large-format tile formats require a specific trowel notch size; some fixtures require a rough-in that differs from what’s in your wall. Run all of this by your contractor before purchasing
- Check warranty requirements — some manufacturers require licensed installation for the product warranty to remain valid. A labour-only contract may inadvertently void that coverage if the contractor doesn’t meet the manufacturer’s certification criteria
If you’re sourcing fixtures or appliances, confirm the model fits your rough-in dimensions before it’s on your driveway. A toilet with a 10-inch rough-in in a 12-inch rough-in bathroom requires an offset flange — a small detail that adds cost and delays. We cover similar planning oversights in our post on renovation mistakes Hamilton homeowners make.
What MTC Renovations Offers Under Labour-Only Arrangements
Our team does take on labour-only projects across Hamilton, Burlington, Dundas, and the broader Halton and Hamilton regions — but selectively. For us to provide an accurate quote on a labour-only job, we typically need:
- A complete materials list with confirmed quantities and product specs
- Products already on-site or confirmed in stock and ready to schedule (not “on order” with an unknown ship date)
- Clear access and staging space at the property — we can’t store material or manage deliveries in a labour-only arrangement
- A scope that doesn’t require us to source, coordinate, or warrant any supply chain items
When those conditions are met, we can price the labour accurately and schedule our crew without surprises. For anything open-ended or where materials are still being decided, we’ll recommend a full contract so both sides are protected.
If you’re not sure which approach fits your project, our home renovation budget guide is a good starting point for understanding full project costs before deciding how to divide responsibilities with your contractor.

Frequently Asked Questions
Do I need a written contract for a labour-only renovation in Ontario? Yes. Ontario’s Consumer Protection Act requires a written agreement for any home renovation service over $50. The contract must include the contractor’s name and address, a clear description of the work, the total price, and the projected start and completion dates. You also have a 10-day cancellation window after receiving your signed copy — this right cannot be waived.
Can a contractor still register a lien on my property under a labour-only contract? Yes. If the contractor or any sub-trade goes unpaid, they can register a Construction Lien against your title under Ontario’s Construction Act. The lien attaches to your property and can block refinancing or a sale. Always hold the statutory 10% holdback until the lien period expires — typically 60 days after the project’s substantial completion date.
What happens if I run short on materials mid-job and the crew has to stop? This is one of the most common friction points in labour-only projects. If your crew arrives and there’s insufficient material to complete the scope, you’ll typically owe a remobilization fee to bring the team back once you’ve resupplied. These fees range from $150 to $500 or more depending on the trade and travel time. Ordering 10–15% extra upfront is almost always less expensive than a second mobilization.
