Contractor Insurance in Ontario
Ontario contractor insurance explained with compulsory WSIB construction coverage, clearance requirements and common private commercial insurance.
Many construction owners and independent operators must have WSIB coverage
WSIB's expanded compulsory coverage rules apply broadly to people who own or run businesses in construction, including many independent operators, sole proprietors, partners and executive officers, with specified exceptions. WSIB guidance says a clearance is required before construction work starts when the compulsory-coverage rules apply.
WSIB — Expanded compulsory coverage in construction Q&A →WSIB does not replace commercial general liability insurance
Workers' compensation and private liability insurance protect against different types of risk. Contractors may also encounter CGL requirements in client or subcontract agreements, along with coverage needs for tools, equipment, commercial vehicles and property.

Insurance checklist before comparing policies
List the operations you actually perform instead of relying only on a broad profession label.
Identify licensing, WSIB, lease and client requirements before comparing optional private coverage.
Include portable tools, stock, equipment, premises, vans, trucks and trailers.
A lower premium can reflect a lower limit, higher deductible or different coverage wording.
Frequently asked questions
There is no single answer based only on the profession name. Ontario requirements can come from trade licensing, WSIB rules, vehicle law, a lease or a client contract. The official context on this page identifies the profession-specific rule we can document; private commercial coverage should be reviewed separately.
Common questions include commercial general liability, tools or property, commercial auto, business interruption and contract requirements. Professional-service businesses may also need to consider E&O and cyber exposure. The right combination depends on actual operations.
Canada Rate Lab does not publish one generic profession premium because operations, revenue, payroll, workers, locations, tools, vehicles, claims, limits and deductibles can materially change the price. Cost ranges will be published only when the business profile and source data can be documented.
No. WSIB is Ontario's workplace insurance system and private CGL or professional liability are commercial insurance products. A business can have WSIB obligations and still need separate private coverage for third-party, property, vehicle or professional risks.
How Canada Rate Lab will build cost ranges
We will not publish one generic small-business premium and apply it to every profession. Future ranges will identify the business activity, province, revenue/payroll assumptions, number of workers, liability limit, vehicles and other meaningful variables. Statutory workplace requirements will be shown separately from the private premium estimate.
