Final answer:
Employer's Liability Insurance is required for employers not covered by provincial workers' compensation acts to protect against employee work-related injury or illness claims. Workman's compensation insurance, which is usually state-mandated, covers employees injured on the job by using funds contributed by employers.
Step-by-step explanation:
To address the question of what type of insurance is needed to ensure the liability of employers is not subject to provincial workers' compensation acts, the answer is B) Employer's Liability Insurance. This type of insurance is designed for employers who may not be covered under the standard workers' compensation act but still need to protect themselves against potential liability claims arising from employee work-related injuries or illnesses that are not covered by workers' compensation.
Workman's compensation insurance is a different type of coverage that is typically mandated at the state level and requires employers to contribute a small percentage of employee salaries to a fund. This insurance pays benefits to workers who are injured on the job. In cases where workers' compensation doesn't apply or an employer is exempt, Employer's Liability Insurance steps in to provide the necessary coverage.
