Hazardous area classification/equipment selection training/course

hi,
I'm newly joined this forum but have consulted it in the past for answers to several questions.
At my work place, I am supervising equipment design and installation (hazardous location environment, Class 1 Zone 1). I work in Ontario primarily.
Are there any courses which are offered that'll provide a good understanding of the CEC/CSA codes applicable to hazardous locations?

Thanks
