Adam Smith Agree, CBC calling it an "investigation" is hyperbolic and misleading.

Without assigning blame: a sad story / outcome, regardless of the quality of journalism.

As a healthcare professional and frequent flier, I'm curious about a few things as well...
- What is this 3rd party US company AC uses? Is there not a Canadian equivalent?
- How much discretion do the pilots have once they've contacted the above company? I know the final call rests with them but to what degree are they obligated to listen to the recommendation of medical company on the ground, or medical professional on board (if there was one)?
- Do all crew members have equivalent first aid training? And is there some sort of procedure or guidance on which crew member is in charge if no health care provider on board to volunteer assistance?

I've heard stories of colleagues assisting with in flight emergencies and contacting this company on the ground who has disregarded and minimized the story and findings of the healthcare provider on board providing assistance. There is, of course, an inherent financial incentive for airlines not to divert when possible.

Finally an observation: regarding the "timeline" of symptoms. While important, the (very limited) information and history provided is almost enough that I would have been advocating for diversion. Chest pain, (+ radiating to your back), vomiting, losing control of your bowels... Those symptoms earn you a high priority CTAS (triage) score in any Canadian emergency room.
