My brother is considering starting a career in commercial diving. He has his advanced Open Water Certificate already but will probably be looking to take a full certification course within the next year. Are there any schools in Canada which you would reccomend?

What options does he have as a commercial diver? What different directions would you reccomend for a 21 year old just starting out? Is a life long career possible?

How long do commercial divers typically work for? I've heard an average of 3-4years and then they get out and work a different angle of the industry like be an ROV technician, off-shore supervisor, or work for a company that hires the divers.

Besides the obvious, what are some of the lesser known dangers in this industry? What is the fatality rate?
