In the hospital sector, there's WSIB. There's a workers compensation board. Depending on the injury, there's a reporting mechanism, and if you need medical assistance, there's time off. You're covered under that type of insurance in hospitals.
In other sectors, depending which group you're part of, there are some insurance services, but I'm not sure exactly what they are. There are some differences in jurisdictions. Having been a nurse in Ontario, I'm just speaking now of Ontario.
