Verify Licensing and Insurance
In Alberta, many trades require a journeyman certificate or a contractor licence issued by Alberta Apprenticeship and Industry Training (AIT). Electricians, plumbers, gas fitters, and HVAC technicians must be licensed — it's not optional, and working with an unlicensed tradesperson puts your home and your insurance coverage at risk.
Before you go any further with a contractor, ask to see their trade certificate or business licence number. You can verify Alberta trade certificates directly through the AIT online registry. For general contractors and renovators, check whether they hold a valid City of Calgary business licence.
Insurance is equally non-negotiable. Every contractor working on your home should carry two types: general liability insurance (covering damage to your property) and Workers' Compensation Board (WCB) coverage for their workers. Ask for a certificate of insurance and call the insurer to confirm it's current — a certificate can be forged or expired.
