Since 1993, the Canadian Working Divers Institute trains commercial divers at a reasonable cost.

The Canadian Working Divers Institute trains commercial divers at a reasonable cost to compete in a growing industry, both nationally and internationally. The commercial diving industry demands travel, long hours, practical skills, self-motivation and strong work ethics and habits. It is not enough that a student enjoys diving; he/she must also enjoy the lifestyle that accompanies the career. This course gives the students the skills and knowledge expected by the commercial diving industry.

All in-water practical projects duplicate (not simulate) actual working environments. At C.W.D.I. projects include more complex underwater work and more time in the water than standards require.

The course consists of 12 consecutive weeks of intensive training. Each week will include:

  • 24 hours theory
  • 24 hours of diving
  • 12 hours of equipment maintenance as well as setting up and breaking down gear
  • 12 hours of independent study and tutoring


  • Grade 12 or equivalent
  • C.P.R. and First Aid (valid to date)
  • SCUBA certification (open water)
  • Diving Medical - By a Hyperbaric Physician - listed at:
