What affects the price

Medicare costs aren't one-size-fits-all. Your monthly premium and out-of-pocket expenses depend on several specific factors. Your zip code matters, as local plan availability varies significantly by region. The type of coverage you select—whether it is a Medicare Supplement or a Medicare Advantage plan—plays a major role in what you pay. Additionally, your current health needs, the specific prescription medications you take, and your preferred doctors can shift your total costs up or down. Because these variables change for every individual, there is no flat rate for everyone. Exact pricing confirmed free on the call.

About this service

These are private policies, often called Medigap, designed to pay for the out-of-pocket costs that the original program does not cover, like copayments. You need this if you want more predictable healthcare spending throughout the year.

Frequently asked in Ontario

Is Medicare free after 65?

Many individuals qualify for Medicare Part A without a monthly premium, which is a great benefit. However, you'll still be responsible for deductibles and coinsurance. Part B usually has a monthly premium, and many people in Ontario choose a Medicare Supplement plan to help manage these out-of-pocket costs.

What is Medicare and what does it do?

Medicare is the federal health insurance program for individuals 65 and older, certain younger people with disabilities, and those with End-Stage Renal Disease. It covers hospital stays (Part A) and medical services (Part B). For comprehensive coverage in Ontario, many residents consider a Medicare Supplement plan.

What are the 6 things Medicare doesn't cover?

Original Medicare generally does not cover long-term care, most dental care, routine vision exams, hearing aids, routine foot care, and cosmetic surgery. These are common areas where Medicare Supplement plans can offer valuable financial assistance to residents of Ontario.

What are the three requirements for Medicare?

The primary requirements are typically being 65 or older and a U.S. citizen or legal resident for at least five years. You may also qualify if you are under 65 and have received Social Security disability benefits for 24 months, or if you have End-Stage Renal Disease.

How much will Medicare cost me each month?

This amount can change annually and is subject to income-related adjustments. Not everyone pays this exact amount; your specific premium might be different. It's best to get a personalized quote for your Medicare Supplement options.
