How to Get Business Insurance Quotes in Ontario
Describe the operation
Describe the operation honestly: trade, services, revenue, payroll, and how much of the work is subcontracted. The classification drives the price more than any discount.
Gather the inputs
Gather the paperwork quotes are built from: vehicle schedule and drivers, prior loss runs, a tool and equipment list, and any contracts that name required limits.
Match limits to contracts
Check every contract for insurance clauses before binding: required limits, additional insured wording, and waiver requests are cheaper to handle up front.
Compare carriers
Shop the same coverage across carriers before binding. Identical operations can quote apart, which makes comparison worth more than most discounts.

FAQ
Business Insurance in Ontario: FAQ
Start with general liability insurance. California requires workers compensation for most employers, commercial auto insurance typically applies to work vehicles, and property coverage follows premises and gear. The local guide for your trade has the detail.
It depends on the trade, payroll, revenue, vehicles, limits, and claims history. The typical California ranges on this page are the starting point; a quote prices each policy against your own operation.
California ties workers compensation to employment: most employers must carry it once they hire, subject to exemptions. Verify current thresholds with the state before adding staff.
Describe the operation accurately, gather loss runs and your vehicle and equipment lists, then compare several carriers against the same limits. Your trade's Ontario guide covers what carriers ask about for that business type.
Usually yes. Homeowners policies typically exclude or sharply limit business activity, so client visits, inventory, and equipment at home generally need their own coverage even for a small operation.
