Quick answer
What is a certificate of insurance for a contractor?
A certificate of insurance (COI) is a one page summary, issued by your broker or insurer, that proves you carry specific coverage: usually commercial general liability, auto and sometimes umbrella, with limits, policy numbers and dates. General contractors, owners, property managers and municipalities ask for it before you start work, often with themselves named as an additional insured.
What a certificate of insurance actually is
A certificate of insurance summarizes your coverage on one page: the insurer, policy numbers, effective and expiry dates, and limits for coverages such as commercial general liability, automobile liability and umbrella. It is issued by your broker or insurer, not by you.
A certificate is evidence, not the policy itself. It does not change your coverage on its own. If a client needs to be an additional insured or needs a waiver of subrogation, your policy must actually include that, and the certificate simply confirms it.

How to get certificates faster
Keep your broker's details handy
Most brokers who work with contractors can issue a standard certificate the same day. Send the client's legal name, address, the project name and any additional insured wording from the contract.
- Client legal name and address
- Project name or address
- Exact additional insured wording


Read the insurance clause before you sign
Contracts sometimes ask for limits or endorsements you do not carry. Catch it before signing so your broker can adjust coverage or you can price it into the job.
- Required limits
- Additional insured and waiver wording
- Notice and deductible clauses

Certificate of Insurance FAQs

Who issues a certificate of insurance?
Your insurance broker or insurer issues it. Contractors should never create or edit their own certificates.
What does additional insured mean on a certificate?
It means the client is covered under your liability policy for claims arising from your work for them. Your policy must include an additional insured endorsement; the certificate only confirms it.
How long does it take to get a certificate of insurance?
A broker who works with contractors can often issue a standard certificate the same day. Special wording can take longer if the policy needs an endorsement.
Is a certificate of insurance the same as a WSIB clearance?
No. A certificate proves your liability and auto insurance. A WSIB clearance certificate proves your WSIB account is in good standing. Most GCs require both.
Does a certificate guarantee I am covered?
No. It is a summary of coverage at the date issued. The policy wording decides what is covered, which is why clients ask for notice if a policy is cancelled.

The Commercial Insurance Difference: Feedback from those referred
Proactive Broker Relationship.
The most noticeable difference 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 business owners.

Security Blanket For My Business
I was always the type of customer that never believed in insurance and only really got it because I had to. Then I connected with a broker through Commercial Insurance.ca and they asked me questions no one else ever 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. Now I look at Insurance as a security blanket for my business.

They had my back
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. Their specialist 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.
