Summary. Business insurance is a contract that transfers defined risks from your business to an insurer in exchange for a premium. In Ontario, some coverage is required by law, including WSIB coverage for most employers and automobile insurance for business vehicles, while other policies are required by your lease, lender, franchisor, or clients. This guide explains the main types of coverage, what drives the cost, and how to get a quote that actually matches your legal obligations.
Business insurance is a contract between your business and an insurance company. You pay a premium, and in exchange the insurer agrees to pay for specific types of losses, such as damage to your property, injury claims from customers, or lawsuits arising from your professional services. The right combination of policies protects the assets you have built, and in many cases you have no choice, because a statute, a regulator, or a contract you signed requires the coverage.
We are business lawyers, not insurance brokers, and we do not sell policies. What we see every week is the legal side of insurance. That means the insurance clauses in commercial leases, service agreements, and franchise agreements, the certificates that landlords and lenders demand, and the disputes that follow when the coverage a business bought does not match the obligations it signed. This article explains business insurance from that vantage point, so you can approach brokers and insurers with a clear picture of what your business actually needs.
What Is Business Insurance?
Business insurance is a legal contract, called a policy, in which an insurer agrees to cover defined losses in exchange for a premium. Every policy has the same basic anatomy. The declarations page identifies who is insured, for what amounts, and for what period. The coverage sections describe the risks the insurer accepts. The exclusions set out what the insurer will not pay for. Endorsements modify the standard wording, and the deductible is the portion of any loss you absorb before the insurer pays.
Two numbers matter most when you compare policies. The limit is the maximum the insurer will pay, per claim and in total for the policy period. The deductible is what you pay first. A low premium often hides a high deductible or a low limit, which is why price alone is a poor way to choose coverage.
In Ontario, insurance companies and insurance agents are licensed and regulated by the Financial Services Regulatory Authority of Ontario, known as FSRA, while independent general insurance brokers are regulated by the Registered Insurance Brokers of Ontario, known as RIBO. Both regulators maintain public directories, so you can confirm that anyone selling you a policy holds a valid licence before you hand over information about your business.

Is Business Insurance Mandatory in Ontario?
Some business insurance is mandatory in Ontario and some is not. The legal requirements come from four directions.
WSIB coverage for employers
The Workplace Safety and Insurance Act, 1997 requires businesses in covered industries to register with the Workplace Safety and Insurance Board, known as the WSIB. Most Ontario businesses that hire workers must register within 10 days of hiring their first full time or part time worker, and the requirement can extend to family members and subcontractors. WSIB coverage is a public workplace injury system rather than a private policy. It pays wage loss and health care benefits to injured workers, and in exchange registered employers are protected from most lawsuits over workplace injuries. Some industries, such as banks and insurance companies, are exempt from mandatory coverage but can apply voluntarily. If you are unsure whether your business must register, check directly with the WSIB, because the consequences of failing to register can include penalties and retroactive premiums.
Automobile insurance for business vehicles
Every vehicle your business owns or leases must be insured. Ontario law sets a minimum of $200,000 in third party liability coverage on every automobile policy, but that minimum is far below what a serious collision can cost, and most businesses carry $1 million or $2 million. Just as important, a personal auto policy generally does not cover commercial use. If you or your employees deliver goods, visit client sites, or haul equipment in a personally insured vehicle, tell the insurer, because undisclosed business use is a common reason claims are denied.
Professional and regulatory requirements
Many regulated professionals must carry professional liability insurance as a condition of practising. Lawyers in Ontario are a familiar example, and similar requirements apply across health, financial, and other regulated fields. If a governing body licenses your work, check its insurance requirements before you open your doors.
Contractual requirements
The most common source of mandatory insurance is not a statute at all. It is the contracts your business signs. Commercial landlords, lenders, franchisors, and large customers routinely require specific coverage at specific limits as a condition of doing business with you. We cover this in detail below, because it is where most of the problems we see actually start.
Everything beyond these categories is optional in law. Very little of it is optional in practice, because a single uninsured loss can end a small business.
What Types of Business Insurance Do Ontario Companies Use?
Most Ontario businesses build their protection from a handful of core policies, then add specialized coverage that fits their industry. The table below summarizes the types you will encounter most often when you request a quote.
| Coverage | What it protects against | Who usually needs it |
|---|---|---|
| Commercial general liability (CGL) | Injury to others and damage to their property arising from your operations, premises, or products | Almost every business, and it is the coverage landlords and clients ask about first |
| Commercial property | Damage to your building, contents, inventory, and equipment from fire, theft, water, and similar perils | Any business with physical premises or valuable equipment |
| Business interruption | Lost income and continuing expenses while you recover from an insured property loss | Businesses that cannot survive weeks or months of closed doors |
| Professional liability (errors and omissions) | Claims that your advice or services caused a client financial loss | Consultants, designers, IT firms, and regulated professionals |
| Cyber liability | Costs of data breaches, ransomware, and privacy claims, including notification and recovery | Any business that stores customer data or depends on its systems |
| Commercial auto | Liability and damage for vehicles used in the business | Any business that owns vehicles or whose staff drive for work |
| Product liability | Claims that a product you made, sold, or distributed caused injury or damage | Manufacturers, importers, retailers, and food businesses |
| Directors and officers | Personal liability of directors and officers for decisions made while managing the corporation | Incorporated businesses with outside investors, boards, or growth plans |
| Crime and fidelity | Employee theft, fraud, and forgery losses | Businesses that handle cash or valuable inventory |
| Equipment breakdown | Sudden mechanical or electrical failure of key equipment | Restaurants, manufacturers, and businesses dependent on machinery |
| Key person insurance | The financial impact of the death or disability of an owner or essential employee | Businesses whose value depends heavily on one or two people |
| Legal expense insurance | Legal fees for certain disputes and proceedings | Small businesses that want more predictable legal costs |
Commercial general liability is the foundation. It responds when a customer slips in your store, when your work damages a client’s property, or when similar third party claims arise, and it typically pays the legal costs of defending you in addition to any settlement or judgment up to the limit.
Professional liability, often called errors and omissions coverage, protects service businesses against something CGL does not, which is pure financial loss caused by your advice or work product. If you sell knowledge or design rather than goods, this is usually the policy that matters most.
Cyber coverage has moved from optional to mainstream. Statistics Canada reported that 16 percent of Canadian businesses were impacted by cyber security incidents in 2023, and that total spending on recovery from those incidents doubled from 2021 to reach $1.2 billion. A standard property or liability policy rarely covers these losses, which is why cyber liability is sold as its own product.
Business interruption coverage deserves more attention than it gets. Property insurance rebuilds your premises, but it does not pay your rent, payroll, or lost profit while you rebuild. Business interruption fills that gap, and for many small businesses it is the difference between reopening and closing permanently.
How Does Your Business Structure Affect Your Insurance Needs?
Your legal structure changes what is exposed when something goes wrong, which changes what you should insure.
A sole proprietorship offers no separation between you and the business. Every business debt and every judgment is your personal debt, which puts your home, savings, and other personal assets on the line. If you operate as a sole proprietor, liability insurance is not just protecting the business. It is protecting you.
A corporation is a separate legal person, so incorporation generally shields shareholders from the corporation’s liabilities. That protection is real, but it is often misunderstood. The corporation’s own assets remain fully exposed to claims, and directors can face personal liability in specific areas such as unpaid wages and certain tax remittances, which is why growing corporations add directors and officers coverage. Incorporation and insurance work together. Neither replaces the other.
Partners in a general partnership are typically each liable for the obligations of the partnership, which multiplies the risk each partner carries and makes adequate liability limits even more important.
If you are choosing or rethinking your structure, our guide to business structures in Ontario explains the options, and our small business lawyers can help you match the structure and the coverage to your plans.
How Do Your Contracts Set Your Insurance Requirements?
In our practice, the documents that actually determine a client’s insurance obligations are rarely statutes. They are contracts.
Commercial leases almost always contain an insurance covenant. A typical clause requires the tenant to carry commercial general liability at a stated limit, to add the landlord as an additional insured, and often to obtain a waiver of subrogation, which prevents your insurer from pursuing the landlord after paying your claim. If your policy does not match the clause, you are in breach of your lease even if nothing has gone wrong yet.
Service agreements and supply agreements frequently require one party to carry coverage and to prove it with a certificate of insurance before work begins. Lenders require property coverage with the lender named as loss payee. Franchise agreements commonly dictate an entire insurance program, including the types of coverage, minimum limits, and who must be named on the policies.
Indemnity clauses and insurance are two halves of the same risk allocation. An indemnity clause is a promise by one party to cover certain losses of the other. That promise is only as strong as the assets and insurance behind it. When we review an indemnity clause, we always ask whether insurance backs the obligation, and whether the policy actually covers liability assumed under contract, because many standard policies limit that coverage. You can read more in our guide to indemnity agreements.
If you hire independent contractors, the same logic applies in reverse. Your contracts should require the contractor to carry their own liability coverage and, where WSIB coverage applies, you should ask for a WSIB clearance before work starts, which confirms the contractor is registered and their account is in good standing. Our guide to independent contractor agreements covers how to build these protections into the contract itself.
How Much Does Business Insurance Cost in Ontario?
There is no single price for business insurance in Ontario, because insurers rate each business individually. The premium you are quoted reflects a handful of factors.
Your industry and risk class matter most. A roofing contractor and a graphic designer with identical revenue will see very different premiums, because the likelihood and size of claims differ. Insurers also weigh your revenue and payroll, your claims history, the limits and deductibles you choose, your location, the age and construction of your premises, and the safeguards you have in place, such as alarms, sprinklers, and cyber security controls.
You control more of this than you might think. Raising your deductible lowers your premium. Bundling property and liability into a business owner’s policy is often cheaper than buying each separately. Documented safety and security practices can earn credits. And because each insurer weighs these factors differently, comparing quotes on identical limits and deductibles routinely reveals meaningful price differences for the same protection.
Premiums, fees, and program details change over time. The figures and requirements described in this article are current as of July 2026, and you should confirm the details with your broker, insurer, or lawyer before relying on them.
How Do You Get a Business Insurance Quote?
Getting a business insurance quote is a straightforward process, and a little preparation makes the result far more useful.
Step 1. Gather your business information. Insurers will ask for your legal name and structure, a description of your operations, annual revenue, payroll and employee count, locations, the value of contents and equipment, your claims history, and any current policies.
Step 2. Pull out every contract that mentions insurance. Your lease, loan agreement, franchise agreement, and major client contracts define the coverage and limits you must buy. Quoting without them is guessing.
Step 3. Choose who you will buy through. Insurance agents represent one or more insurers and are licensed by FSRA. Independent brokers deal with multiple insurers and are regulated by RIBO. Both regulators publish directories, so verify the licence of anyone you deal with.
Step 4. Request quotes on identical limits and deductibles. You cannot fairly compare a $1 million policy with a $500 deductible against a $2 million policy with a $5,000 deductible. Fix the coverage first, then compare the price.
Step 5. Read the exclusions and conditions before you buy. The cheapest quote often excludes the very risk you were trying to insure.
Step 6. Match the certificate of insurance to your contracts. Before you sign a lease or start work for a client, confirm the certificate shows the required limits, endorsements, and named parties.
What to have ready before you request a quote
- Legal business name, structure, and year established
- A plain description of what the business actually does
- Annual revenue and projected revenue
- Payroll and the number of employees and contractors
- Business locations, owned or leased, with square footage
- Replacement value of contents, inventory, and equipment
- Vehicles used for business purposes
- Claims and losses over the past five years
- A copy of every contract clause that requires insurance
- Current policies and renewal dates
When Should You Talk to a Business Lawyer About Insurance?
A broker places your coverage. A lawyer makes sure your legal obligations and your coverage line up. Talk to a business lawyer before you sign a lease, service agreement, or franchise agreement that contains insurance requirements, when you are buying a business and need to know what coverage and liabilities come with it, when an insurer denies a claim you believe is covered, and when you are structuring or restructuring a corporation and want liability protection and insurance working together.
Frequently Asked Questions
Is business insurance required by law in Ontario?
Some coverage is required. Most employers must register with the WSIB after hiring their first worker, every business vehicle needs automobile insurance with at least $200,000 in third party liability coverage, and many regulated professions must carry professional liability insurance. Beyond that, the requirements usually come from your lease, lender, franchisor, or client contracts.
What is the difference between an insurance agent and a broker?
An agent represents one or more insurance companies and is licensed by FSRA. An independent broker deals with multiple insurers on your behalf and is regulated by RIBO. Both must hold valid licences, and both regulators publish public directories where you can verify anyone offering to sell you a policy before sharing your business information.
Does a corporation still need insurance if it has limited liability?
Yes. Incorporation generally protects shareholders’ personal assets, but the corporation’s own assets remain fully exposed to claims, and directors can face personal liability in areas such as unpaid wages and certain remittances. Insurance protects the value inside the corporation, and directors and officers coverage protects the people running it.
What is a certificate of insurance?
A certificate of insurance is a summary document issued by an insurer or broker confirming that coverage is in place, showing the policy types, limits, and effective dates. Landlords, lenders, and clients request it as proof of coverage. It is not the policy itself, so always confirm the underlying policy wording actually matches your contractual obligations.
What does additional insured mean?
An additional insured endorsement extends parts of your policy’s protection to another party, most often a landlord or client who required it in a contract. If a claim arises from your operations, the additional insured can access your coverage. Landlords ask for this in almost every commercial lease, and a missing endorsement can put you in breach.
How often should you review your business insurance?
Review your coverage at least once a year at renewal, and any time the business changes in a meaningful way. New locations, new services, new equipment, your first employees, business vehicles, or a major contract with insurance requirements should all trigger a fresh look, because coverage that matched last year’s business may not match this year’s.
