What it is

A small team of certified commercial divers and a surface supervisor who inspect, clean and carry out light repairs underwater. Typical jobs include docks, wharves, bridge piers, water intakes, culverts, reservoirs and boat ramps, often with camera or photo reports.

Your first three steps

  1. Train and certify through an accredited commercial diving school, and gain on-the-job experience with an established contractor
  2. Check your province's occupational health and safety rules for diving crews, and get a quote for liability, marine and WCB/WSIB coverage
  3. Register as a supplier with local municipalities and marinas, and ask to be added to their quote or tender lists
Who pays

Municipalities, water utilities, marinas, port and harbour authorities, hydro and industrial sites, and property managers with waterfront assets.

How it makes money

Day rates or fixed quotes per job, plus charges for equipment, travel and inspection reports. Work often comes through repeat contracts and tender lists.

Skills that help
  • Commercial diver certification
  • Safe dive planning and supervision
  • Basic underwater repair and inspection
  • Clear reporting and quoting
Watch out for
  • Commercial diving is tightly regulated. Check with your provincial occupational health and safety regulator about crew size, supervisor and equipment requirements, and about how the CSA Z275.2 occupational safety code for diving operations applies in your province
  • Insurance is costly and often required for tenders. Check commercial general liability, marine and WCB/WSIB rules in your province
  • Equipment such as surface-supplied air, a standby diver kit and a boat or truck is a major upfront cost
  • Winter freeze-up and weather can pause work in much of Canada, so plan cash flow for the off-season
  • Diving is high-risk work, so check every safety, medical and first-aid requirement before taking jobs
