Running a business comes with a lot of moving parts, and unfortunately, disputes are a reality that most business owners will face at some point. Whether it is a client who has not paid, a partner who is not holding up their end of the deal, or a disagreement among shareholders, these situations can feel overwhelming. Commercial litigation is the legal process used to resolve these kinds of disputes, and understanding how it works can help you make better decisions when things go wrong.
This article gives a general overview of common business disputes in Ontario and some things to think about if you find yourself in one. It is not legal advice, and every situation is different, so you should speak with a lawyer to understand your options.
What is Commercial Litigation?
Commercial litigation refers to legal disputes between businesses, or between a business and an individual, that typically involve money, contracts, or business relationships. These cases are usually handled in the Ontario Superior Court of Justice or, for smaller amounts, in Small Claims Court (which handles matters up to $50,000 as of the current rules).
Litigation can be expensive and time-consuming, so it is rarely the first step. Most experienced business lawyers will look at whether the dispute can be resolved through negotiation or another method before heading to court.
Common Types of Business Disputes in Ontario
1. Unpaid Invoices
This is one of the most common issues businesses face. If a client or customer has not paid for goods or services, you may have the right to pursue them through the courts. Depending on the amount owed and the terms of your agreement, there may be different options available to you. Acting sooner rather than later is usually better, as there are limitation periods in Ontario that can affect your ability to bring a claim.
2. Breach of Contract
When one party to a contract does not do what they agreed to do, that may be considered a breach. This could involve a supplier who failed to deliver, a contractor who did not complete work, or a client who walked away from a signed agreement. In these situations, the party who suffered a loss may be able to seek compensation, depending on the terms of the contract and the facts of the situation.
If you are dealing with a contract dispute, it helps to gather all written communications, the original contract, and any relevant records as early as possible.
3. Shareholder Disputes
Disagreements between business partners or shareholders can be some of the most difficult situations to navigate. These disputes can arise over how the business is being run, how profits are distributed, or what happens when someone wants to leave the company. Ontario's Business Corporations Act provides some protections for shareholders, including in cases of oppressive conduct by a majority shareholder or the company's directors.
Shareholder disputes can escalate quickly, so getting legal advice early, before the relationship breaks down completely, is generally a good idea.
4. Injunctions
An injunction is a court order that requires someone to do something or stop doing something. In a business context, injunctions may be sought in situations involving a former employee who has breached a non-compete or confidentiality agreement, a competitor using trade secrets, or someone interfering with your business operations.
Injunctions are urgent in nature and courts in Ontario have strict tests they apply before granting them. If you think you may need one, you should speak with a lawyer as quickly as possible, because timing can matter a great deal.
Settlement Strategy: Resolving Disputes Without Going to Trial
Most commercial disputes in Ontario do not actually go to trial. Many are resolved through negotiation, mediation, or other forms of settlement before the case gets that far. In fact, Ontario courts encourage parties to consider mediation, and in some jurisdictions it is a mandatory step in the process.
A good settlement strategy takes into account the strength of your position, the cost and time involved in continuing litigation, and the potential impact on your business relationships. Sometimes it makes sense to push for a trial, but in many cases, a negotiated settlement can save money and get you a result faster.
Remember: going to court is not always the best path forward. Your lawyer can help you weigh the options and think through what makes sense for your specific situation.
Practical Tips If You Are Facing a Business Dispute
Keep records of everything. Emails, contracts, invoices, and notes from meetings can all be important.
Do not ignore the problem. Business disputes rarely resolve themselves, and waiting too long can limit your options.
Respond carefully to written demands. What you say in writing can matter later, so get legal advice before responding to a formal letter.
Look at your contracts. Your agreements may already have dispute resolution clauses that affect how a dispute must be handled.
Act within limitation periods. In Ontario, there are generally time limits for bringing legal claims. Missing a deadline can mean losing your right to pursue the matter.
Frequently Asked Questions
Q1. How long does commercial litigation take in Ontario?
The timeline can vary widely depending on the complexity of the dispute, how busy the courts are, and whether the parties are willing to settle. Simpler matters in Small Claims Court may be resolved within several months, while more complex cases in the Superior Court of Justice can take a year or more, and sometimes longer. Speaking with a lawyer early can help you get a realistic picture of what to expect in your situation.
Q2. Do I need a lawyer for a commercial dispute?
While it is possible to represent yourself in some matters, commercial litigation can be complicated, and the decisions you make early in a dispute can affect the outcome. Having a lawyer review your situation can help you understand your rights, your obligations, and your options before you commit to a course of action.
Q3. Can I recover my legal costs if I win?
In Ontario, courts have discretion to award costs to a successful party, but this does not necessarily mean you will recover all of your legal fees. The amount, if any, will depend on the circumstances of the case. You should not assume that winning means your legal costs will be fully covered.
Q4. What is the difference between mediation and litigation?
Mediation is a process where a neutral third party helps the parties try to reach a voluntary agreement. It is generally faster and less expensive than going to court, and it keeps the outcome in the hands of the parties rather than a judge. Litigation, on the other hand, involves the court making a binding decision. In some cases, trying mediation first can be a practical and cost-effective step before committing to a full lawsuit.
