Contractor Insurance in Alberta
How WCB-Alberta coverage, clearance letters, insurance certificates and private commercial coverage fit together for contractors and subcontractors.
Hiring an uninsured contractor can create coverage responsibility for the principal
WCB-Alberta says that if a company hires a contractor or subcontractor who does not have, or may not be eligible for, their own WCB account, the hiring company may be responsible for providing coverage and paying premiums on that contractor's behalf.
WCB-Alberta — Contractors and subcontractors →Alberta also tells consumers to check liability insurance
Alberta's official guidance for hiring contractors recommends checking that contractors and tradespeople have WCB coverage and asking to see an insurance certificate showing public liability and property damage coverage for workers on the job.
That is practical consumer guidance. It should not be converted into a claim that every Alberta contractor is legally required to carry the same private-liability limit.
Alberta — Hiring a contractor →Why clearance letters matter
WCB-Alberta recommends requesting a clearance letter before a contractor or subcontractor starts. The letter can confirm whether the business has WCB coverage, the industry the coverage applies to and whether the account is in good standing. WCB also recommends checking again before payment because a principal can become responsible for outstanding premiums in some circumstances.
A business can also make WCB coverage a condition of the contract. That is different from asking for proof of commercial general liability insurance.
WCB worker coverage in compulsory industries
If an Alberta employer operates in an industry where workers' compensation is compulsory, WCB says an account must be opened within 15 days of hiring the first worker. The definition of workers can include full-time, part-time, temporary, casual and certain contract or subcontract workers.

No single Alberta contractor price makes sense
A solo contractor doing light installation work does not present the same insurance exposure as a contractor with crews, heavy equipment, commercial vehicles and large project contracts. Canada Rate Lab's future cost dataset will segment contractor pricing by trade, revenue or payroll, workers, vehicles, liability limit and other meaningful variables.
