Broken shoulder blade.... that does not sound like a good time. We can call you Enea.It's definitely possible to hurt yourself on the 125s. I broke a collarbone and shoulder blade during an endurance race. Apparently you have to really eff up to break your shoulder blade. The nurses were all very impressed.
I went through my workplace general health insurance for that. Although after this discussion, it looks like maybe you could be covered under the statutory accident benefits of your regular car insurance. The legal logic is convoluted and there's not a clear-cut answer.
In any case, Racer5's insurance is to cover them in case of liability. From what I understand, it could be used by the government to recover OHIP costs, or to pay out if someone sued Racer5. It would not be your first avenue of compensation.
I guess I have to read the fine print on my work insurance.
I can't find anything that offers track day personal disability insurance.
