The Role of Indemnity Clauses in Ontario’s Commercial Contracts

When companies sign a contract, they aren’t just making a deal to buy or sell stuff. They are also figuring out who pays the bill if things go wrong.

Let’s say someone gets hurt, a building gets damaged, or a company gets sued for copying an idea. Somebody has to pay for the lawyers and the fines.

That’s where an “indemnity clause” comes in. Think of it as a promise in the contract that says: “If this specific bad thing happens, I will pay for it so you don’t have to.”

It doesn’t mean one person takes the blame for everything that goes wrong; it only covers the exact problems they agreed to take on.

If you are thinking about studying law, starting a business, or working in Ontario, knowing how this rule works is super important. This guide explains how these agreements work in Ontario, how they differ from buying insurance, and how judges treat them in real court cases.

What is an Indemnity Clause?

Basically, an indemnity clause is just a promise. One side agrees to protect the other side from losing money or facing lawsuits while they work together. The contract must spell out exactly what kinds of problems it covers.

Think of it like a financial shield. But this shield only works if the rules are written clearly, without hidden exceptions, and the person making the promise actually has the cash to pay up.

Here is an example: Let’s say Company A promises to protect Company B. If a customer sues Company B because of a mistake Company A made, Company A has to step up. They must pay for Company B’s lawyers and cover any court fines. But this only works if the specific problem was actually listed in their agreement, and Company B tells Company A about the lawsuit right away.

Another important rule is the “duty to defend.” In Ontario, just because someone promises to pay damages at the end of a lawsuit doesn’t automatically mean they have to hire lawyers and fight the battle in court for you from day one.

If you want the other company to take over the actual legal fight, the contract has to clearly say they have a “duty to defend.” If it is written in there, that company has to step in, hire the lawyers, and take control of the case as long as you inform them quickly and cooperate.

In insurance law (such as in the foundational case Progressive Homes Ltd. v. Lombard General Insurance Co. of Canada), the duty to defend is generally triggered by the “pleadings” – meaning it is based simply on what the person suing is alleging. Ontario courts have sometimes applied insurance-duty principles by analogy to express commercial duties to defend, but the result depends on the precise contract. In other cases, ordinary service contracts have been held to create an indemnity without a separate duty to defend.

Control of the defense depends on the clause. The indemnified party may retain control, the indemnifying party may assume control, or the parties may share responsibility. Conflicts of interest can also require separate counsel. A duty to defend is a significant obligation because it can require payment of substantial legal costs before liability is established.

If the contract only includes a duty to indemnify (without a duty to defend), the indemnifying party might only have to reimburse the indemnified party for covered losses after liability or loss is established under the clause. An indemnity obligation may arise following a settlement, judgment, incurred loss, or another contractually defined trigger; a completed trial is not always necessary.

It’s also really important to know that an indemnity promise is not the same thing as actual insurance.

If a company promises to pay your losses, that promise is only useful if it has the money. If they go broke, their written promise is useless. Because of this, business contracts in Ontario usually force the company making the promise to buy real commercial insurance. This ensures real money is available if a disaster happens.

But even with insurance, there are no perfect guarantees. Insurance policies come with strict rules, like limits on how much they will pay out, deductibles, and lists of things they straight-up refuse to cover. The promise written in the contract and the actual insurance policy are two totally different things. Sometimes, the insurance payout won’t be enough to cover the entire bill the contract promised to pay.

Often, a contract will demand that your name gets added directly to the other company’s insurance policy so you are protected directly (they call this being an “additional insured”). And a quick heads-up: just because a company hands you a piece of paper that says “we have insurance,” it doesn’t automatically mean they bought the exact coverage the contract asked for. You always have to double-check the real policy details.

Types of Indemnities

Not all indemnities are structured the same way. Depending on the negotiation leverage of the parties and the nature of the transaction, they can take different forms.

Indemnity vs. Limitation of Liability

It is common to see an indemnity clause and a limitation of liability clause side by side in an Ontario commercial contract. While they both deal with risk, they do completely different things.

Think of a “limitation of liability” clause as a hard ceiling. It sets a strict maximum on how much money someone can be forced to pay if they mess up. For example, a software creator might write in the contract, “If my software breaks your computers, the most I will ever pay you back is the total amount you paid me this year.” This rule also blocks you from suing for indirect, domino-effect losses.

An indemnity clause does something completely different. Instead of capping the money, it shifts financial responsibility. It forces one side to step up and pay for specific disasters. This often includes bills they normally wouldn’t have to pay, like the other person’s lawyer fees if a random third person sues them.

Because these two rules do opposite things, you have to read them together. What happens if Company A promises to cover all legal costs (the indemnity), but another part of the contract says they will never pay more than $50,000 (the limitation)? Usually, the $50,000 ceiling wins. The promise still stands, but the actual cash payout stops at 50k.

To fix this clash, lawyers write in exceptions, which they call “carve-outs.” A contract might say, “Our total limit is $50,000 except for the things we promised to cover under the indemnity rule.”

But forcing a company to promise an unlimited amount of money is super dangerous. One big lawsuit could completely bankrupt them. So, instead of signing a blank check, companies usually agree to safer options. They might create a separate, higher limit just for indemnity (a “super-cap”), tie the payout limit to whatever their insurance covers, or remove the ceiling only for a few very specific, extreme risks.

How Indemnities Work in Practice: Real-World Scenarios

To see how these concepts apply in practice, let’s look at how an indemnity agreement works across four types of Ontario commercial contracts.

SaaS (Software as a Service) Agreements

Let’s look at a real-world example: a small tech startup in Ontario sells its accounting software to a massive bank in Toronto.

Because banks handle billions of dollars and highly sensitive information, they will demand two major protections in the contract: one for stolen code, and one for data hacks.

1. The Stolen Code Problem (Intellectual Property)

What if a third-party software company sues the bank, claiming, “Hey, that startup copied our code, and now you are using it!”

Even though the bank didn’t write the code, it’s the one getting sued. Because of the indemnity rule, the startup has to step up, hire the lawyers, and pay any settlement money so the bank doesn’t lose a dime.

But there are strict rules. The bank cannot just secretly make a deal with the other company or admit fault without asking the startup first. Also, the startup can walk away if the bank caused the problem, like if it tinkered with the code, mixed it with unsupported software, or stubbornly kept using it after being told to stop.

2. The Hacker Problem (Data Breaches)

What if a security bug in the software lets hackers steal the bank customers’ personal data?

The startup will likely have to pay for the massive cleanup. This doesn’t just mean paying standard court fees. The startup might have to hire cyber experts to investigate the hack, send warning letters to every affected customer, buy credit-monitoring services for them, and answer to government investigators.

If the government hits the bank with huge penalty fines for the leak, the startup might have to pay those fines too, as long as local laws allow someone else to cover that specific type of fine.

Construction Contracts

Construction sites are dangerous places. When a main builder in Ontario hires a roofing crew for a project, they will include a strict indemnity clause in the contract.

Here is why: Imagine one of the roofers accidentally drops a hammer and hurts someone walking by on the sidewalk. That injured person will probably sue everyone involved, both the roofing crew and the main builder who runs the site.

Because of the indemnity rule, the roofing crew has to take the hit. Since it was their mistake, they must pay for the main builder’s lawyers and whatever money the judge awards to the injured person.

But there is a big catch. What if the main builder was also being careless? Maybe they forgot to put up safety fences below the roof. In Ontario, judges usually say you cannot force someone else to pay for your own sloppy mistakes. If the main builder wants the roofer to pay for the builder’s own mess-ups too, the contract has to say that in incredibly clear, exact words.

Lastly, you cannot use this contract rule to dodge the law. The government has strict safety rules for construction sites. If the law says the main builder is responsible for keeping the work zone safe, they can’t just pass that legal duty to the roofer by writing it in a contract. If safety inspectors show up, the main builder still has to answer to them.

Commercial Leases

Let’s say you open a clothing store inside an Ontario shopping mall. Before handing you the keys, the mall owner (the landlord) will make you sign a lease that includes an indemnity agreement.

Now imagine a customer walking around your store, slipping on a puddle of water, and breaking their arm. Because people usually try to sue everyone involved, that customer will likely sue both your business and the mall owner.

This is where your indemnity promises kick in. It shields the mall owner. Since the accident happened inside your space, the agreement usually requires you (the tenant) to pay the mall owner’s legal bills and cover whatever the court awards to the injured customer.

But it isn’t always a 100% cut-and-dry situation. Who actually ends up paying the final bill can change depending on a few key details:

• Who caused the mess? Did your employee spill a mop bucket, or was water leaking from a broken pipe in the mall’s ceiling?
• What does the lease actually say? Contracts usually split up exactly who is responsible for maintaining and cleaning different parts of the property.
• Did the landlord mess up too? If the landlord was also careless – like ignoring your emails about a leaky roof for weeks – a judge might decide they have to pay their own share of the damages instead of dumping the whole bill on you.

Mergers and Acquisitions (M&A)

Imagine you buy a used phone from someone and take over their mobile plan. If the phone has a cracked screen, you can clearly see it before you buy it. But what if the old owner secretly owes $500 on that phone bill? If you take over the account, that old debt suddenly becomes your problem.

Buying a whole business (what lawyers call a “share purchase”) works the exact same way. You aren’t just buying their office and their profits; you are buying the company’s entire history.

Before handing over the money, the buyer makes the seller promise that the business is financially healthy and doesn’t owe any secret debts. But let’s say six months after you buy the company, the government (the Canada Revenue Agency, or CRA) comes knocking. They audited the company and found the old owner skipped out on a massive tax bill two years ago.

Because you own the company now, the CRA expects you to pay that bill.

This is exactly why buyers demand an indemnity clause. Since the seller broke their promise that the taxes were fully paid, the indemnity rule lets you force the old owner to pay you back for that surprise bill.

But you can’t just ask for a refund whenever you feel like it. The contract usually puts some strict rules on how this works:

• Time Limits (Survival Periods): You can’t hold the seller responsible forever. But because the CRA can take years to audit a company, tax indemnities usually stay active way longer than other parts of the contract.
• Minimums (Baskets or Deductibles): You can’t drag the seller into a legal fight over a $50 math error. The contract usually sets a minimum amount you have to lose before you can trigger the indemnity and demand a refund.
• Maximums (Caps): There is often a ceiling on the most cash the seller must pay back.

Finally, the contract usually includes an “exclusive remedy” rule. This means the indemnity payout is the only way you can fix this specific problem. You can’t use a surprise tax bill as an excuse to cancel the entire business buyout or sue the seller for other random things unless you can prove they intentionally scammed you (which the law calls fraud).

Ontario Case Law on Indemnity Clauses

When a dispute arises, how do courts handle an indemnity clause?

Ontario courts interpret them using ordinary contractual interpretation principles, with close attention to text, context, and commercial purpose. Following the modern approach in the leading Supreme Court of Canada decision in Sattva Capital Corp. v. Creston Moly Corp., 2014 SCC 53, courts consider the text in light of the factual matrix and the agreement as a whole. The surrounding circumstances cannot overwhelm or rewrite the contractual language.

A major Canadian legal precedent that highlights this specific approach to indemnities is Resolute FP Canada Inc. v. Ontario (Attorney General), 2019 SCC 60. While ultimately decided by the Supreme Court of Canada, this litigation worked its way up through the Ontario court system and focused on a settlement agreement governed by Ontario law.

The case involved a paper mill in Dryden, Ontario, that had historically leaked mercury into nearby rivers. In the 1980s, the Ontario government wanted a new company to buy the mill to save local jobs. To encourage the sale, the province granted the buyers an indemnity agreement protecting them from “any claim” related to the previous pollution.

Decades later, the Ontario Ministry of the Environment ordered the current owner, Resolute, to perform expensive environmental cleanup work. Resolute argued that the provincial indemnity protected them. The motion judge found the indemnity applied. The Court of Appeal majority also found it applied but concluded Resolute could not claim under it and remitted issues concerning Weyerhaeuser. Ultimately, the Supreme Court of Canada reversed those decisions and ruled against Resolute.

The Supreme Court majority held that the indemnity did not apply to the regulatory order because, read in context, it addressed third-party pollution claims rather than the first-party compliance order. The Court did not establish that “any claim” always means a third-party claim. The result depended on the entire agreement, the settlement context, and the notice and defense provisions, as well as the factual matrix.

The lesson from this case is that general wording may not capture a risk not supported by the agreement as a whole. While express wording is advisable where the parties intend to cover regulatory orders, statutory compliance costs, or first-party government claims, interpretation still considers the entire agreement.

Drafting and Reviewing an Effective Indemnity Clause

When drafting an indemnity agreement in Ontario, clarity is your strongest defense. You must also keep Ontario’s Limitations Act, 2002 in mind.

Under the Limitations Act, 2002, you generally have a two-year limitation period to bring a legal claim once a problem is discovered, subject to statutory rules and exceptions. Furthermore, Ontario generally has a 15-year ultimate limitation period, subject to exceptions and the detailed statutory rules. Ontario’s Act contains a specific rule for contribution and indemnity claims: the claim is generally deemed discovered when the claimant is served with the underlying claim or settles it, subject to the statutory wording.

A contractual survival period and a statutory limitation period are different. The survival clause determines how long a contractual promise or representation continues; the limitation period determines when a proceeding must be commenced. Contracts must be drafted carefully to specify exactly how long an indemnity obligation survives and whether the survival period is intended as a contractual condition, substantive expiry of liability, or limitation-period variation. Section 22 permits parties to certain business agreements to vary or exclude some limitation periods, subject to specific rules, though the ultimate period has additional restrictions.

It is also critical to understand the legal distinctions between related concepts. A release extinguishes claims; an indemnity creates a payment obligation. A guarantee supports another person’s obligation, while an indemnity may create a primary obligation. If the clause includes “hold harmless” phrasing, clarify whether it is intended to prevent the indemnified party from bearing covered losses in the first place or is merely part of the indemnity wording. Finally, where several parties contribute to a loss, statutory and contractual contribution rights may affect the allocation.
