A business liability premium in Canada is an insurer's estimate of how often a business like yours is sued or blamed for injury or damage, how expensive those claims are to defend and settle, plus provincial premium taxes, commissions and a margin. Two insurers can rate the same bakery, roofer or consultant very differently because each uses its own classification and rating model. These guides explain the moving parts so you can see why a quote is high and which levers are actually yours.
Start with the overview of business liability insurance costs. It links to guides on the rating factors insurers use, the difference between commercial general liability (CGL) and professional liability, how to choose a limit of $1 million, $2 million or $5 million, and the taxes that some provinces add to commercial premiums.
Insurance in Canada is regulated by each province and territory, and Quebec runs on the Civil Code rather than common law, so two guides cover provincial differences and the rules worth re-checking in 2026. Every dollar figure on this site is an illustrative example, not a market rate; rules are described as they stand in October 2026, with the official source to confirm them.
