Thank you, Mr. Chair.
I would like to thank all the witnesses for their powerful testimony.
Mr. McMillan, the figures you quoted are sobering and frankly riveting. Thank you for putting names, people and a human element to this issue. I think that's very important. I'd like to address some questions to you.
First of all, I'm curious about the most common causes of occupational carcinogens. Do we know what chemicals or what causes are responsible for the cancers being experienced by firefighters disproportionately?
