diploma rather then a certificate only, if you are choosing to make it a career path
i worked as OH&S manager for over 10+ years in the patch, and Partnership provincial safety auditor
in a time before OH&S certificate programs were so required, and when actual work experience was the prefered value (rant off)
the fact is that human resources dictates the terms of employees, and they don't recognize less then a diploma, so that or better is your ticket
toward that end goal, align your time and money in training that will further you to achieving a CRSP (canadian registered safety professional)
with a CRSP you'd be in demand, a diploma will get you in the door, a certificate is a starting point only really, but will be entry for the more minor position(s)
there are some specific training in certain fields (O&G and Construction, being a couple of the largest)
here's a link to the CRSP website, start there IMO
