Dispute with a renovation contractor in Canada: steps, complaints and small claims
How to resolve a renovation dispute in Canada, from documenting and demand letters to consumer protection complaints, BC's Civil Resolution Tribunal and small claims limits by province.
Most renovation disputes (unfinished work, defects, unapproved extras, a contractor who stops showing up) are resolved fastest by documenting everything, putting your complaint in writing with a clear request and deadline, and paying only undisputed amounts while keeping the holdback. If that fails, you can complain to your provincial consumer protection office (which can act on breaches of consumer law, though it does not usually decide private damages), try mediation, or go to small claims court: in Ontario up to $50,000 (since 1 October 2025), in British Columbia through the Civil Resolution Tribunal for most claims up to $5,000 and the Provincial Court for $5,001–$35,000, and in Quebec's Small Claims Division up to $15,000. Limitation periods apply, so do not wait.
This guide belongs to the pitfalls and official sources overview. See also renovation warranties, cost overruns and change orders and deposits, holdbacks and payment schedules. This is general information, not legal advice.
Step 1: document
- The contract, change orders, invoices, receipts and proof of payment.
- Dated photos and videos of the work and the problem.
- Emails and text messages; notes of phone calls with dates.
- Inspection reports and permit records.
- An independent opinion where useful, for example from another contractor, a home inspector or an engineer.
Step 2: write to the contractor
Send a written complaint (email and, for important letters, registered mail). State:
- what the contract required,
- what is wrong, with photos,
- what you want (repair, completion, refund, credit),
- a reasonable deadline,
- that you will pursue other remedies if it is not resolved.
Keep it factual. Offer a site meeting.
Step 3: manage payments carefully
- Pay amounts that are not in dispute on time; withholding everything can put you in breach.
- Keep the statutory holdback until the lien period expires.
- If the contract allows a deficiency amount, withhold a reasonable sum tied to the specific defects.
- If a lien is registered, get legal advice before paying anything further.
Step 4: consumer protection offices
| Province | Office | What it can do (summary) |
|---|---|---|
| Ontario | Consumer Protection Ontario | Receive complaints, mediate some disputes, enforce the Consumer Protection Act; it publishes charges and convictions |
| British Columbia | Consumer Protection BC | Enforce the Business Practices and Consumer Protection Act, including direct sales rules |
| Alberta | Alberta consumer protection services | Investigate breaches of the Consumer Protection Act, including prepaid contracting licence rules |
| Quebec | Office de la protection du consommateur | Information on rights, formal notice templates, enforcement of the Consumer Protection Act |
| Quebec (licensing) | Régie du bâtiment du Québec | Licence matters and claims on licence security in eligible cases |
These offices generally cannot order the contractor to pay you damages in a private dispute; for that you need a court or tribunal, though a complaint can still prompt a resolution and helps them track patterns.
Step 5: mediation or negotiation
Mediation is often faster and cheaper than court. Some provinces and courts offer mediation services; private mediators are also available. A settlement should be written, signed, and say exactly what will be done and paid.
Step 6: small claims and tribunals
| Province | Forum | Monetary limit (check before filing) |
|---|---|---|
| Ontario | Small Claims Court | Up to $50,000 since 1 October 2025 (previously $35,000) |
| British Columbia | Civil Resolution Tribunal | Most small claims up to $5,000 |
| British Columbia | Provincial Court (small claims) | $5,001–$35,000 |
| Quebec | Court of Québec, Small Claims Division | Up to $15,000; parties generally represent themselves |
| Other provinces | Provincial small claims courts | Limits vary; check your court's website |
Claims above the limit go to the higher courts, where costs and complexity rise. You can sometimes reduce a claim to fit the limit, but you then give up the excess.
Limitation periods
Generally two years from discovery of the claim in Ontario, British Columbia and Alberta, with ultimate limits, and three years in Quebec. Lien deadlines are much shorter (weeks, not years). If deadlines are close, get legal advice now.
Worked example: valuing a small claim
Illustrative, Ontario. A contractor abandoned a basement finish after drywall. The contract price was $60,000 before tax, or $67,800 with 13% HST. The owner has paid $40,000, and $4,000 of the work invoiced so far is being kept as the statutory holdback. A second contractor quotes $28,000 plus HST ($31,640) to finish the same scope.
- Still unpaid under the original contract: $67,800 − $40,000 = $27,800 (this includes the $4,000 holdback).
- Cost to finish with the second contractor: $31,640.
- Extra cost caused by the abandonment: $31,640 − $27,800 = $3,840.
- The owner's claim might be about $3,840 plus documented extra costs, but the holdback must still be handled under the lien rules, because subcontractors or suppliers of the first contractor may claim against it.
This kind of calculation is what a court will look for. A lawyer or paralegal (in Ontario, licensed paralegals can appear in Small Claims Court) can help.
Paying by credit card
If you paid a deposit by credit card and the contractor never started, your card issuer may have a dispute (chargeback) process with its own time limits. Contact the issuer quickly.
FAQ
Can I just stop paying?
Withholding undisputed amounts can put you in breach of contract. Keep the holdback and a reasonable deficiency amount where allowed, and pay the rest.
Can I hire someone else to finish?
Possibly, if the contractor has abandoned the work or refuses to fix it after notice, but terminating a contract has legal consequences. Send written notice first and get advice.
Do I need a lawyer?
Not for every small claim, but for liens, large amounts or a contract termination, legal advice is worth it.
