What is contractors insurance?
Contractors insurance is a programme of separate policies arranged around a construction operation rather than a single contract. It combines liability for injury and damage caused to others, property coverage on the tools and equipment the contractor owns, coverage for work in progress, and automobile coverage for the vehicles used. Surety bonds sit alongside it as a separate instrument.
A surety bond is not insurance and does not work like it. A bond is a three-party guarantee: the surety promises the project owner that the contractor will perform, and the contractor indemnifies the surety for anything it pays out. Insurance transfers risk away from the contractor; a bond ultimately leaves it with the contractor.

How much does contractors insurance cost in Ontario?
The factors that move an Ontario contractors insurance premium, in approximate order of influence, and why insurers look at each one.
| Rating factor | Why |
|---|---|
| Trade classification | Roofing, excavation and structural work sit far above interior finishing classes. |
| Annual revenue and payroll | Contractor liability rates are applied per unit of revenue or payroll. |
| Work at height and hot work performed | Falls and torch work are the two largest severity drivers in construction. |
| Subcontractors used and their limits | Uninsured subcontractors transfer their exposure back to the hiring contractor. |
| Value of owned equipment scheduled | The equipment schedule is the insurer's exposure on theft or total loss. |
| Residential against commercial and institutional work | Each segment carries a different completed-operations claim pattern. |
| Claims history over the past five years | Loss history is a filed underwriting factor for every commercial insurer. |
| Health and safety programme in place | Documented training and site procedure reduce both frequency and severity. |
What insurance is a contractor required to carry in Ontario?
Workplace safety insurance coverage through the Workplace Safety and Insurance Board has been mandatory in Ontario construction since 1 January 2013, extending to most independent operators, sole proprietors and partners. No provincial statute requires commercial general liability for most trades. Under Ontario's Construction Act, public contracts at or above the prescribed threshold require performance and payment bonds.
Beyond those requirements, coverage is driven by contract. Which policies are arranged, and at which limits, depends on circumstances that vary from one contractor to the next:
- What limits the general contractor, project owner or municipality specifies, and which parties must be named as additional insured.
- The trades performed, and whether they include roofing, excavation, hot work or work at height.
- The value of owned and leased equipment, and where it is stored overnight.
- Whether subcontractors are engaged, and whether their certificates are collected and current.
- Whether the contractor provides any design or engineering input alongside the physical work.
- Whether projects require bid, performance or labour and material payment bonds.
What situations does contractors insurance commonly address in Ontario?

Frequently asked questions
What insurance does a contractor need in Ontario?
An Ontario contractor programme commonly combines commercial general liability, contractors equipment, tools coverage, non-owned automobile liability and, where design input is provided, contractors professional liability. Workplace safety insurance through the Workplace Safety and Insurance Board is mandatory in construction. Which policies apply depends on the trades performed and the contracts in force.
Is WSIB coverage mandatory for Ontario contractors?
Workplace safety insurance coverage through the Workplace Safety and Insurance Board has been mandatory in Ontario construction since 1 January 2013, extending to most independent operators, sole proprietors and partners in construction. A limited exemption applies to certain executive officers and partners who perform no construction work. The WSIB determines eligibility in each case.
Do I need a surety bond in Ontario?
Under Ontario's Construction Act, a contractor on a public contract at or above the prescribed threshold must furnish a performance bond and a labour and material payment bond. Private owners and general contractors impose bonding requirements by contract. Whether a bond is required on a given project is set by the tender documents or the contract.
What is the difference between a surety bond and insurance?
Insurance is a two-party contract that transfers risk from the insured to the insurer. A surety bond is a three-party guarantee: the surety promises the project owner that the contractor will perform, and the contractor indemnifies the surety for anything it pays. A paid bond claim is recovered from the contractor; a paid insurance claim is not.
Does contractors insurance cover faulty workmanship?
Commercial general liability wordings exclude the cost of correcting the contractor's own faulty workmanship, and they exclude damage to the particular part of the property being worked on. Resulting damage to other property is commonly covered. That distinction is where most Ontario construction coverage disputes sit, and the issued policy governs.
Are tools covered if they are stolen from a work van in Ontario?
Tools coverage responds to theft from a vehicle on most Ontario contractor wordings, subject to the scheduled and unscheduled limits and to a forcible-entry requirement. Tools left in an unlocked vehicle are excluded on most wordings. Limits, sub-limits and security conditions vary by insurer, and the issued policy governs.
