Business insurance (often called commercial insurance) is an insurance program that protects your company from financial loss when things go wrong. A typical Ontario business insurance package can include:
Commercial general liability (CGL) for third party bodily injury and property damage
Commercial property insurance for buildings, contents, and equipment
Business interruption insurance for lost income when you are forced to shut down after an insured event
Professional liability (errors and omissions) for advice and professional services
Cyber insurance for data breaches, ransomware, and other digital risks
Commercial auto for vehicles used in your business
Other specialty coverages based on your industry
The Government of Ontario recommends business insurance even for home based businesses,
because it protects your property, operations, and ability to generate income.
In practice, business insurance can help you:
Meet landlord, lender, and contract requirements
Handle the cost of legal defence and settlements after a lawsuit
Recover from property damage more quickly
Protect your reputation and relationships with customers
Sleep better at night, knowing a single event is less likely to shut you down

Small business insurance is simply business insurance tailored to smaller operations. It often combines several coverages into one package. Common options include:
Even very small or home based businesses can benefit, especially if you see clients in person, use specialized equipment, or store customer data.

Business liability insurance (often CGL) protects your company if you are held legally responsible for:
It usually covers legal defence costs, out of court settlements, and court judgments, up to the policy limits. For most Ontario businesses, CGL is considered a cornerstone of their insurance program.

Commercial property insurance protects your physical assets, for example:
It typically responds to events like fire, wind, some types of water damage, theft, and vandalism, depending on the policy wording.

If your business provides advice or professional services, you may need professional liability insurance, also known as errors and omissions (E&O). It can help protect you from claims that a mistake, omission, or negligent advice caused a client financial harm.
This is particularly important for consultants, agencies, technology providers, health professionals, and any business where clients rely on your expertise.

Cyber threats are now one of the most significant risks facing businesses of all sizes in Ontario. A data breach, ransomware attack, or business email compromise can create:
Cyber insurance can help with incident response, legal costs, data restoration, notification expenses, and in some cases ransom related expenses, depending on the policy. It is a vital complement to your general liability policy, which usually does not fully address cyber risk.
There is no single law that says every Ontario business must carry a generic business insurance policy.
However, certain coverages are mandatory in specific situations:


Exact exclusions depend on the policy, but business insurance commonly does not cover:
There can also be sub limits for items like money, data, or specialty equipment. This is why it is important to review wording with a broker who will point out what is not covered, not just what is.
Most small businesses in Ontario start with:
Your exact needs depend on your industry, contracts, and risk tolerance.
Some practical ways to manage the cost of business insurance include:
The goal is to find savings that do not leave you dangerously underinsured.
Business liability insurance (CGL) typically covers bodily injury and property damage to third parties, such as a customer slip and fall or damage at a client site. Professional liability insurance (E&O) covers financial losses that arise because of mistakes, errors, or omissions in your professional services or advice. Many service oriented businesses need both types of coverage.
Yes, in many cases. The Ontario government specifically notes that business insurance is recommended even for home based businesses, because standard home insurance often does not cover business related liability, equipment, or stock.
A tailored small business or home based business policy can extend appropriate protection to your operations.
You can buy business insurance directly from insurers or work with a broker. The Ontario government recommends getting multiple quotes and speaking with a broker who understands commercial coverage.

The most noticeable difference between the team at CommercialInsurance.ca and everyone else was the fact that I no longer felt that I was needed to manage the broker... the brokers came to me with proactive recommendations and knew when to push and shop the market and when not to. When the topic of business insurance comes up, I always refer fellow buinsess owners to commercialinsurance.ca.


"I was always the type of custom that never beleived in insurance and only really got it because I had to. Then I met the people at CommcercialInsurance.ca and they asked me questions no one else every did and that's how I knew something was different. They took the time to understand and evaluate the risks. Well, I ended up getting some extra coverage (legal expense) and thank goodness I did. Something fairly innocent turned into something quite nasty and I didn't have to do too much... my coverage took care of it. Nows I look at Insurance as a security blanket for my business."


No one likes buying insurance because it's a bit of a bet against yourself. You just hope that when the bad things happen that insurance will do what it said it would do in the first place. That's what'ts great about the experience is over here. They stand behind the policy's that they bind. They never professed to get me the best price, but they did say they have my back, and have my back, they did.
