Insurer
An insurer is the insurance company or organization that provides financial protection to individuals or groups in exchange for premium payments. The insurer assumes the risk of potential loss and agrees to pay benefits for covered claims according to the terms of the policy. Insurers evaluate applications, determine premiums, issue policies, and manage claims through underwriting and administration processes.
How It Works
An insurer pools risk by underwriting insurance and annuities, collecting premiums, building and investing reserves, and making the contractual payments it has promised, with fees set according to the expected incidence of the insured risk and the expected return on investment. For accident and sickness coverage under Canada's Insurance Companies Act, the insurer undertakes to pay a sum of money toward a person's health care, including dental and preventative care, and in Quebec's Insurers Act that activity is defined as undertaking to make a payment under an insurance contract if a covered risk occurs. Insurers may offer both individual and group products, and they are regulated by federal and provincial authorities to maintain solvency, transparency, and compliance with consumer protection laws.
Example:
Say you buy a personal health and dental policy from a Canadian insurer such as a provincial Blue Cross, Sun Life, or Manulife. That company is your insurer, so it reviews your application, collects your premiums, and pays eligible claims, like a portion of a dental cleaning or a prescription drug cost, according to your policy's terms. If instead you are covered through your employer's group benefits plan, your employer is the plan sponsor while the insurer is the company that administers and guarantees those benefits.
What to Watch For:
Under a group plan, remember that your employer is not the insurer. Your employer is the policyholder or plan sponsor, while the insurer administers and guarantees the benefits. With a personal health plan, you usually pay a monthly premium for coverage, so check your policy to find out whether your insurer covers only a percentage of each claim or only a maximum annual amount. For critical illness insurance, insurers may differ in how they define critical illness and which conditions they cover, and the insurer usually pays the benefit after the diagnosis.
