What Is a Contract Dispute in Ontario?
A contract dispute arises when one or more parties to an agreement disagree about whether a contractual duty has been fulfilled, whether the terms and conditions of the contract have been breached, or what remedy is available following a breach. In Ontario, contract law is governed by both common law principles and specific statutes — including the Consumer Protection Act, the Sale of Goods Act, the Commercial Tenancies Act, and the Construction Act — each of which imposes specific rights and obligations on contracting parties.
A material breach of a contractual obligation — one that goes to the heart of the agreement and defeats the purpose for which the contract was made — gives the non-breaching party the right to seek damages, rescission, specific performance, or other available remedies. Our contract dispute lawyer team analyzes every agreement and every set of circumstances to identify the strongest legal theory for your specific dispute.
Types of contract disputes our contract lawyers regularly handle:
- Breach of commercial supply agreements and service contracts
- Construction contract disputes under Ontario’s Construction Act — including holdback releases, proper invoices, and interim adjudication proceedings
- Partnership and shareholder agreement disputes — including disputes over profit sharing, authority, buy-sell provisions, and shotgun clauses
- Commercial lease conflicts — including disputes over CAM charges, exclusive use provisions, and alleged illegal lockouts
- Employment contract violations — including breach of non-compete and non-solicitation covenants
- Real estate contract disputes — including misrepresentation, failed conditions, and rescission claims
- Technology and software agreement disputes
Understanding the types of contract disputes applicable to your specific situation is the first step toward an effective legal strategy. Our contract lawyer toronto team provides practical advice on the strength of every claim and the remedies most likely to deliver a favourable outcome for your business.
Breach of Contract — Legal Remedies Available in Ontario
When a breach of a contractual obligation occurs, Ontario law provides several categories of remedies depending on the nature and severity of the breach. Our contract dispute lawyer team advises every client on which remedies are available and pursues them aggressively through negotiation, mediation, arbitration, or litigation.
Damages — the most common remedy for a breach of contract. Our litigation lawyers pursue:
- Expectation damages — placing you in the financial position you would have been in had the contract been fully performed
- Reliance damages — reimbursing you for expenses wasted in anticipation of the contract being performed
- Consequential damages — compensation for foreseeable losses caused by the breach that go beyond the direct value of the contract itself, including lost profits and lost business opportunities
Specific performance — a court order requiring the breaching party to fulfill their contractual obligation. This equitable remedy is available in specific circumstances — particularly where the subject matter of the contract is unique, such as real estate or proprietary business assets. Our contract dispute litigation team regularly seeks specific performance as an alternative or supplement to damages in high-value commercial disputes.
Rescission — canceling the agreement entirely and restoring both parties to their original positions. Rescission is an important remedy where a contract was induced by misrepresentation or where a fundamental breach has made the agreement commercially worthless. Our contract lawyers have successfully pursued rescission claims in commercial real estate, supply agreements, and franchise disputes.
Injunction — an urgent court order preventing a party from taking an action that would cause irreparable harm during the dispute. Our civil litigation team regularly obtains injunctions to freeze assets, prevent the dissipation of proceeds, and stop a breaching party from continuing conduct that damages our client’s interests while the litigation proceeds.
Remedies for a breach in the construction context are particularly complex — our Construction Act specialists advise on holdback rights, lien claims, and interim adjudication as rapid alternatives to full court proceedings.
Material Breach vs. Minor Breach — Understanding the Distinction
Not every failure to perform under a contract constitutes a material breach that entitles the innocent party to terminate the agreement or claim significant damages. Understanding the distinction is critical to every contract dispute litigation strategy.
A material breach — sometimes called a significant contractual duty failure — occurs when the breach goes to the root of the agreement and deprives the innocent party of substantially the entire benefit of the contract. A material breach entitles the innocent party to treat the contract as terminated and sue for full expectation damages.
A minor breach — a technical or partial failure that does not defeat the purpose of the agreement — entitles the innocent party to claim damages for their actual loss but does not justify terminating the agreement or stopping their own performance.
Our contract lawyer team analyzes every set of facts carefully to determine whether a breach rises to the level of a material breach — because characterizing the breach incorrectly can itself create liability. Businesses and individuals that stop performance in response to a minor breach can find themselves in breach of the contract, exposing them to a counter-claim.
Construction Contract Disputes — The 2026 Construction Act
Construction contract disputes in Ontario involve a distinct legal framework under the Construction Act — and the 2026 amendments have significantly changed how these disputes are handled.
As of January 1, 2026, mandatory annual holdback releases are now required for all multi-year construction projects in Ontario. The interim adjudication window has been expanded to 90 days following project completion — providing a faster and less expensive alternative to full court proceedings for payment disputes, scope disputes, and contract interpretation issues. Bill 60 (2025) has also tightened notice periods for commercial and residential defaults.
Our contract dispute lawyer team advises contractors, subcontractors, owners, and developers on every aspect of construction contract disputes under the 2026 framework — including proper invoice requirements, holdback release obligations, lien rights, and the interim adjudication process. Our construction litigation lawyers have extensive experience navigating the statutory adjudication process to secure payment faster than traditional civil litigation.
Alternative Dispute Resolution — Mediation, Arbitration, and Adjudication
Many commercial contract disputes can be resolved more efficiently and cost-effectively through alternative dispute resolution (ADR) than through traditional court proceedings. Our contract dispute lawyer team is experienced in every form of ADR available in Ontario:
Mediation — a structured negotiation process facilitated by a neutral mediator in which the parties work toward a mutually acceptable resolution. Mediation is particularly effective in disputes where the parties have an ongoing business relationship that they wish to preserve. Our contract lawyers prepare every client thoroughly for mediation and negotiate aggressively to achieve the best possible settlement.
Arbitration — a private adjudication process in which an arbitrator hears evidence and makes a binding decision. Many commercial contracts include mandatory arbitration clauses. Our civil litigation lawyers have extensive experience representing clients before commercial arbitrators in Ontario — presenting the same quality of evidence and legal argument as in court proceedings.
Statutory adjudication — under the 2026 Construction Act, interim adjudication provides a rapid, binding resolution of specific construction contract disputes without the cost and delay of full court proceedings. Our construction contract dispute team uses adjudication strategically to secure interim payments and resolve scope disputes quickly.
Dispute resolution strategy — our contract lawyers advise every client on the dispute resolution mechanism best suited to their specific contractual dispute — whether that is direct negotiation, mediation, arbitration, adjudication, or litigation on the Commercial List of the Ontario Superior Court of Justice.
What NOT to Do After a Contract Breach
Do not stop performance without legal advice. Withholding payment or stopping your own performance without proper legal justification can put you in breach — exposing you to a counter-claim for damages. Always consult a contract dispute lawyer before taking any unilateral action in response to a perceived breach.
Do not delete electronic communications. Emails, Slack messages, text messages, and other digital communications are frequently the most critical evidence in commercial litigation cases. Preserve everything — including drafts and internal communications — from the moment you suspect a dispute is developing.
Do not sign an amending agreement under pressure. If the breaching party pressures you to agree to new terms or sign an amendment after a breach has occurred, any signature could waive your right to sue for the original failure. Review every proposed amendment with our contract lawyer team before signing.
Do not miss limitation periods. Most contract disputes in Ontario are subject to a 2-year limitation period from the date the breach occurred or was discovered. Construction Act adjudication claims have a 90-day window. Many individual contracts impose even shorter notice periods — some as short as 7 to 14 days. Contact our contract dispute lawyers immediately to ensure your right to legal action is preserved.
How Our Toronto Contract Dispute Lawyers Handle Your Case
Step 1 — Book a Consultation
We analyze the contract language, review the relevant correspondence, and assess the strength of your breach claim. We identify every available remedy and advise on the fastest and most cost-effective path to resolution. Our practical advice at this stage prevents many clients from making costly procedural mistakes.
Step 2 — Demand and Negotiation
We issue a formal Notice of Default where required, preserve all evidence, and pursue direct negotiation or mediation to resolve the dispute without the cost of full litigation where possible. Many contract disputes are resolved at this stage with favourable outcomes for our clients.
Step 3 — Litigation or Adjudication
Where negotiation fails, our litigation lawyers initiate proceedings — whether through the Commercial List of the Ontario Superior Court of Justice, statutory adjudication under the Construction Act, or private arbitration. We present compelling legal arguments, manage evidence disclosure, and pursue every available remedy including injunctions where required.
Step 4 — Enforcement
We enforce every judgment or settlement obtained — including through asset seizure, garnishment, and contempt proceedings where the breaching party refuses to comply with a court order or arbitral award.
What Compensation Can You Recover in a Contract Dispute?
Our contract dispute lawyer team pursues every available head of recovery in commercial contract litigation:
- Expectation damages — putting you in the financial position you would have been in if the contract was performed
- Reliance damages — reimbursing wasted expenses incurred in anticipation of the agreement
- Restitution — forcing the breaching party to return any unjust enrichment they received at your expense
- Specific performance — a court order compelling completion of the contract
- Punitive damages — in rare cases of high-handed or bad faith conduct, courts may award damages beyond your actual loss
- Debt collection — recovery of unpaid invoices, holdbacks, and contractual amounts owing
- Legal costs — in successful commercial litigation cases, a portion of your legal representation costs may be recoverable
Our contract lawyers calculate every head of damages available in your dispute — including consequential losses and lost profits — to ensure your recovery reflects the true financial impact of the breach.

Frequently Asked Questions — Contract Dispute Lawyer Toronto
How long do I have to sue for breach of contract in Ontario?
The general limitation period for contract dispute litigation in Ontario is 2 years from the date of the breach. The 2026 Construction Act provides a 90-day adjudication window. Individual contracts may impose shorter notice periods — some as brief as 7 to 14 days. Contact our contract dispute lawyers immediately to protect your right to legal action.
What if the contract was verbal?
Verbal contracts are legally binding in Ontario for most commercial matters. Under Canadian law, our contract lawyers use Course of Conduct evidence — including emails, invoices, and patterns of behavior — to establish the terms of an oral agreement and prove the breach.
How much does a contract dispute lawyer cost?
We offer flexible billing structures — including hourly rates for advisory work and No Win No Fee models for qualified high-value commercial litigation. Contact us for a free consultation to discuss your matter and the billing arrangement best suited to your dispute.
Can I claim for lost profits in a breach of contract case?
Yes. Where lost profits were a foreseeable consequence of the breach at the time the contract was entered into, courts will award damages — including compensation for lost business opportunities and disrupted operations. Our contract lawyers work with forensic accountants to calculate and document every element of consequential loss.
What is the difference between mediation and arbitration in a contract dispute?
Mediation is a facilitated negotiation where a neutral mediator helps the parties reach a voluntary settlement — the mediator does not impose a decision. Arbitration involves a neutral arbitrator who hears evidence and makes a binding decision, similar to a court judgment. Our contract dispute lawyer team advises on which process is most appropriate for your specific dispute.
