Check out IHSA's occupational health risk booklets ! These booklets, created by Ontario's Infrastructure Health & Safety Association (IHSA), contain prevention information for workers and a diagnostic toolkit for physicians and primary health providers. They are available for many trades on IHSA's website. Type "diagnostic toolkit for physicians" into their search window. The last two pages of each four-page booklet are to be provided to your doctor; they give your doctor information about the health risks of your job.
