Business Insurance Liability and Medical? - medical liability insurance

I am interested in setting up a similar business in a temporary employment agency and I wonder, given the nature of the business insurance. (Ontario, Canada). There is no official car.
I would also like an explanation for the cost of health insurance for workers in general, what are the costs of insurance and how it is calculated and paid?
Are there any good companies to buy in? I have connected to the Great West Life insurance business from my old job, but I do not understand how it works or how the call from outside my small part.
