If you operate a manufacturing facility in Ontario, you almost certainly carry a Commercial General Liability (CGL) policy. Most lenders require it, most landlords require it, and most customer contracts demand a certificate before your first delivery. But a CGL policy is not a blanket shield. When a third party is injured on your plant floor, the outcome depends entirely on the details: who the visitor was, why they were there, what caused the fall, and whether your policy wording covers that specific situation. Many Ontario manufacturers discover the gap only after a claim is filed. This guide explains where those gaps appear, what coverage fills them, and what a decision maker needs to do before the next renewal, the next contract tender, or the next site visit from a customer.

Who this applies to
This article is written for owners, CFOs, operations managers, and risk managers at Ontario manufacturing businesses. That includes light manufacturers assembling components in Brampton or Mississauga, food processors operating in Hamilton or the Kitchener area, metal fabricators and machine shops across southwestern Ontario, plastics and rubber producers, custom fabricators working to client specifications, and contract manufacturers producing under a third party's brand. It also applies to businesses that are in the process of expanding to a second location, hiring a new shift, or beginning cross border sales into the United States.
If any of the following apply to you right now, your coverage deserves a close look before the next policy year:
- You are responding to an RFP or tender that requires specified liability limits.
- Your landlord is requesting an updated certificate of insurance naming them as an additional insured.
- You have added a new production line that changes your product output or introduces new raw materials.
- You have recently hired temporary labour, students, or contractors who are on site regularly.
- A customer or distributor is requiring you to carry products liability limits above your current program.
- You are about to ship product into the United States for the first time.
Each of these triggers can create an underwriting or coverage issue that your existing policy was not designed to address.
What is covered and not covered
What a standard CGL policy does cover
A Commercial General Liability policy is designed to cover bodily injury and property damage claims brought against your business by third parties. On paper, that sounds comprehensive. In practice, there are important carve outs that affect manufacturers specifically.
Standard CGL coverage typically responds when a client visiting your facility trips on a wet floor near the reception area, when a delivery driver is injured in your loading dock area, or when property belonging to a visitor is damaged due to your negligence. It also responds to most advertising injury claims and to legal defence costs associated with a covered claim.
Where coverage falls short on the plant floor
The employer's liability exclusion is one of the most significant gaps. A CGL policy excludes claims brought by your own employees. If a worker is injured on the plant floor, that claim routes through the Workplace Safety and Insurance Board (WSIB) system in Ontario, not your CGL policy. However, many manufacturers also have contractors, agency workers, and temporary staff on site. Whether those individuals are covered by your CGL or excluded as de facto employees is a question that comes down to underwriting definitions and policy wording, and the answer is not always obvious.
The products and completed operations hazard operates as a sub limit or separate insuring agreement in many programs. If your product leaves the facility and injures someone downstream, the products liability component responds, not the premises component. Some lower cost CGL policies sold to manufacturers carry sublimits on products coverage that are far below the premises liability limit. If you have never verified those two numbers separately, now is the time.
Consider this practical example. A quality assurance inspector from a retail chain visits your plant for an audit. She walks through the active production area and is struck by a component that detaches from an overhead conveyor. Your CGL premises liability should respond. But if your policy has a contractual exclusion that eliminates coverage for injuries occurring in areas not disclosed to the insurer, or if the production area was added after policy inception without an endorsement update, the insurer may dispute coverage. That dispute takes months to resolve and your legal defence costs accumulate in the meantime.
A second practical example: a maintenance contractor your facility hires to service equipment is injured while working on your press. His employer carries WSIB coverage, but he also pursues a tort claim against your business. Whether your CGL picks that up depends on whether the contractor qualifies as an "insured contractor" under your wording and whether you have executed a hold harmless agreement with his employer.

Common claim scenarios for this business type
Premises liability claims remain the most frequent source of third party injury disputes in Ontario manufacturing facilities. Wet floors near cleaning stations, unguarded floor openings, poor lighting in secondary corridors, and forklift traffic in shared pedestrian zones all contribute to falls and collision injuries involving visitors.
The following scenarios represent real patterns in Ontario manufacturing liability claims:
- A customer's engineer visits for a product inspection and slips on coolant spill near a CNC machine, sustaining a fractured wrist.
- A courier delivering packaging material is struck by a forklift while waiting near a receiving door that lacked a designated pedestrian zone.
- A municipal fire inspector conducting a scheduled inspection falls on an unmarked step near a secondary exit.
- A prospective client on a facility tour is exposed to fumes in a finishing room where ventilation signage was not posted.
- A contracted cleaning crew employee is injured using equipment your facility provided, and their employer lacks adequate coverage.
In each scenario, the injured party is not your employee and the injury occurs on your premises. That sounds like a textbook CGL claim. But each scenario also contains a detail that can trigger a coverage dispute: the undisclosed area, the contractor relationship, the equipment ownership question, or the regulatory inspection context. Knowing these patterns in advance lets you address them in your policy before a claim forces the issue.
If a claim does occur, understanding your obligations early matters. Review Boardwalk Insurance's claims support process so you are not improvising after the fact.
Cost drivers and underwriting questions insurers actually ask
When an underwriter prices plant floor liability insurance in Ontario, they are assessing the probability and severity of a third party injury claim. The questions they ask are designed to reveal operational exposures that standard application forms often miss.
Expect questions about the following:
- Annual revenue and the proportion generated by products shipped outside Ontario or into the United States.
- The nature of your manufacturing process: is it automated, semi automated, or heavily manual?
- Visitor volume: how many non employees enter the facility in a typical month and for what purposes?
- Contractor management: do you have written agreements with all contractors on site, and do you verify their insurance certificates?
- Claims history: any bodily injury or property damage claims in the past five years, including claims you believe were groundless.
- Products: do you sell under your own brand, under a customer's label, or both?
- US exposure: do any of your products reach American consumers, either directly or through a distributor?
- Safety protocols: do you have a formal visitor management process, documented safety orientations for non employees, and signage compliant with Ontario's Occupational Health and Safety Act?
Underwriters will also look at your property schedule and ask whether your building values are adequate. An underinsured property program often signals to underwriters that the account has not been properly reviewed in years, which can affect how they price the liability component as well. You can review your property exposure alongside your liability program at Boardwalk Insurance's Commercial Property Insurance page.
How to reduce premium without reducing protection
Reducing your cost of insurance as an Ontario manufacturer does not require accepting less coverage. It requires demonstrating to underwriters that your operation is managed with discipline. The following risk controls have a measurable effect on pricing at renewal.
- Implement a formal visitor management program that includes sign in, a safety briefing, PPE requirements, and escort protocols in production areas.
- Maintain written contractor agreements with hold harmless clauses and require current certificates of insurance from every third party working on site.
- Document and repair housekeeping deficiencies on a regular schedule: spills, lighting failures, and unmarked hazards are the leading contributors to premises liability claims.
- Conduct an annual policy review with your broker to ensure all operations, products, locations, and revenue streams are accurately disclosed. Undisclosed operations are the most common source of coverage disputes.
- Separate your products liability sublimit from your premises limit and verify both against your customer contract requirements before each tender or renewal.
- If you ship into the United States, confirm that your CGL policy includes a US jurisdictional clause or arrange a standalone US products liability endorsement.
If your fleet of vehicles transports product or raw materials between facilities, your CGL does not cover vehicle related injuries. That exposure requires a separate commercial auto policy. Review Commercial Auto and Fleet Insurance in Ontario to ensure that gap is closed.
Quick checklist
Use this checklist before your next renewal or before signing a contract that requires a certificate of insurance:
- Confirm your CGL premises liability limit meets the minimum required by your customer contracts and landlord lease.
- Verify that your products liability sublimit is equal to or greater than your premises limit if you ship product offsite.
- Confirm that all plant locations, including any new or recently added facilities, are listed on the policy schedule.
- Ensure all contractors working on site have provided current certificates of insurance before they enter the building.
- Confirm your policy includes coverage for US jurisdiction if any product reaches American end users.
- Review whether temporary workers and agency staff are adequately addressed in your WSIB registration and your CGL wording.
- Check that your business interruption coverage is tied to your current revenue, not the revenue figure from three years ago.
Mistakes that cause coverage gaps
The most expensive coverage gap in Ontario manufacturing insurance is the one that was never noticed until a claim arrived. These are the mistakes Boardwalk brokers see most often when reviewing an existing manufacturer's program:
Relying on a policy that has not been updated since the last expansion. Every time you add a location, a product line, or a significant revenue increase, your policy needs to be formally updated. An endorsement is not automatic.
Assuming WSIB covers all workers on site. WSIB applies to your employees. Independent contractors may or may not be covered depending on their status and your WSIB classification. If a contractor's injury results in a tort claim against your business, your CGL is the first line of response. If that contractor was not disclosed to your insurer, you may face a coverage dispute.
Accepting a customer's standard certificate requirements without verifying your policy meets them. Many Ontario manufacturers sign supply agreements that require specific liability limits, additional insured endorsements, and waiver of subrogation clauses. If your current policy does not include those endorsements, the certificate your broker issues may not satisfy the contract, exposing you to breach of contract risk alongside the underlying liability risk.
Ignoring cyber exposure on the plant floor. Increasingly, Ontario manufacturers operate connected equipment, PLCs, and automated systems that are potential targets for cyber events. A cyber incident that causes physical damage or shuts down production is not covered by your CGL or property policy without a specific cyber endorsement. Review Cyber Liability Insurance for Ontario businesses if your facility relies on networked operational technology.
Treating business interruption as optional. If a third party injury on your plant floor results in a regulatory shutdown of your facility pending investigation, your revenue stops. Your CGL pays the injured party's claim. It does not replace your lost income. Business Interruption Insurance fills that gap and is increasingly required by lenders and large customers as a condition of doing business.
FAQ
Does my CGL policy cover a visitor who is injured on my loading dock?
Generally yes, if the loading dock is listed as part of your insured premises and the injury results from your negligence. However, if the dock area is leased separately, was added after inception, or if the injured party qualifies as a contractor under your policy wording, the insurer may dispute coverage. Disclose all premises areas to your broker at each renewal.
Is a temporary worker from a staffing agency covered under my CGL if they are injured on my floor?
Temporary workers are typically excluded from your CGL as de facto employees, meaning their injury would route to WSIB. However, if a staffing agency worker is injured and pursues a tort action against your business, your CGL defence provision may respond. The outcome depends on your policy wording and the worker's classification. Confirm this with your broker before your next placement of agency staff.
My customer wants me listed as an additional insured on their policy. Does that eliminate my need for my own coverage?
No. Being named as an additional insured on a customer's policy provides limited and conditional protection. You need your own CGL policy to protect your own interests, satisfy your landlord's requirements, and meet lender obligations.
What limits should an Ontario manufacturer carry on a CGL policy?
A minimum of two million dollars per occurrence with a four million dollar aggregate is common for small to mid size manufacturers in Ontario. Businesses supplying large retailers, automotive OEMs, or public sector customers often need five million dollars or more. US exposure can require higher limits still. Review your customer contracts for the required minimums before your next renewal.
Does my CGL cover injuries that happen because of a defect in my product after it leaves the facility?
That falls under the products and completed operations section of your CGL, not the premises section. Verify that your policy does not carry a sublimit on products coverage that is materially lower than your premises limit, and confirm the products coverage territory includes all jurisdictions where your product is distributed.
What is the difference between an occurrence form and a claims made form for a manufacturer?
An occurrence form covers incidents that happen during the policy period, regardless of when the claim is filed. A claims made form covers claims reported during the policy period. Most Ontario manufacturers are better served by an occurrence form because product liability claims often surface years after the incident. Confirm your policy form with your broker.
How does WSIB interact with my commercial general liability policy in Ontario?
WSIB provides no fault coverage for work related injuries to your registered employees and eliminates their right to sue your business directly in most cases. Your CGL covers third party claims from people who are not your employees. The two programs operate in parallel. Gaps appear when worker classification is ambiguous or when a contractor's WSIB status has not been verified.
Can I get a certificate of insurance that names multiple customers as additional insureds?
Yes. Most CGL policies can be endorsed to name multiple additional insureds, though each endorsement may carry conditions. Some customers require blanket additional insured wording. Others require specific endorsements by name. Confirm the exact wording your customer requires before issuing the certificate, because a certificate that does not match the contract requirement can trigger a breach of contract dispute.
