Life Insurance and Your BMI: What to Expect If You're Overweight
Life insurance when you're overweight or have a high BMI: how Canadian insurers use build tables, where cut-offs fall, and what a rating adds to the cost.
If you are carrying extra weight and wondering whether it will stop you from getting life insurance, the short answer is: almost certainly not, but it may affect your rate. Canadian insurers use height-and-weight build tables, which line up closely with BMI, to place applicants in a health class. Many people with a BMI in the 30s are approved at standard rates. Most of the rest receive a rating that raises the premium rather than a decline. It is the combination of weight with other conditions that produces the difficult files.
This article is for Ontario adults who are overweight or have obesity and want to know what an underwriter will actually do with that information. We cover how build tables work, where the cut-offs tend to fall, why weight is seldom assessed by itself, how recent weight loss and surgery are treated, and what a rating adds to the cost. We are insurance advisors, not physicians, so this is about how insurers make decisions, not health guidance.
Build tables, not just BMI
Insurers do not literally ask for your BMI. They ask for height and weight and compare them to a build table that sets a maximum weight for each height at each health class. The tables are proprietary and differ between companies, but they translate quite closely into BMI bands, which is why BMI is the easiest way to talk about them.
A few things that surprise people:
- Every insurer has its own table. The same 5’10” and 240 lb applicant might be standard at one company and rated at another.
- The tables set maximums for each class, so your build affects not only whether you are approved but whether you qualify for the discounted preferred and preferred plus classes.
- Muscular applicants sometimes get caught by the tables. If you are a competitive athlete or strength trainer with a high weight and low body fat, say so, because some underwriters will consider waist measurement or body composition instead.
For a full walk-through of health classes and how they are assigned, our guide to life insurance underwriting is the place to start.
Where the lines usually fall
The table below describes the general pattern across Canadian insurers, expressed as BMI for convenience. It is a guide to what we commonly see, not a rulebook, and individual companies deviate from it in both directions.
| Approximate BMI | Typical assessment (build alone, no other conditions) |
|---|---|
| Under 18.5 | May be rated or asked for more information; very low weight raises its own questions |
| 18.5–27 | Standard; preferred and preferred plus classes usually available |
| 27–30 | Standard at most insurers; preferred plus often out of reach, preferred sometimes available |
| 30–34 | Standard at many insurers; mild rating (roughly 25–50%) at others |
| 35–39 | Rating of roughly 50–125% at most insurers; standard at a small number |
| 40–44 | Rating of roughly 100–200%, or a postponement; some insurers decline |
| 45 and above | Traditional coverage often declined; simplified or guaranteed issue usually still available |
Ratings in Canada are typically expressed as a percentage added to the standard premium. A “+50%” rating means you pay one and a half times the standard rate for the same coverage.
Age matters too. Underwriters are generally somewhat more tolerant of a higher build in older applicants than in younger ones, on the reasoning that a 30-year-old with a BMI of 38 has more years for related conditions to develop than a 60-year-old with the same build.
It is rarely weight alone
The most important thing to understand is that build is one input among several, and the underwriter is really asking whether the extra weight is already affecting your health. That is why the paramedical exam and the application questions matter so much.
The conditions that most often compound a high BMI in underwriting:
- High blood pressure, treated or untreated. Our article on life insurance with high blood pressure explains how it is assessed.
- Elevated blood sugar or type 2 diabetes. Blood tests from the paramedical will show HbA1c and fasting glucose regardless of what you report. See life insurance for diabetics.
- Sleep apnea, diagnosed or suspected. Treated apnea with good CPAP compliance is often fine; untreated apnea alongside a high BMI usually is not. Our guide to life insurance with sleep apnea has the details.
- Cholesterol and liver enzymes outside the normal range.
- Family history of early heart disease or diabetes.
- Smoking. A smoker with a high BMI is rated on both counts and the effects compound.
Here is the practical consequence. A person with a BMI of 36, normal blood pressure, normal blood work and no sleep apnea will often receive a modest rating or, at some insurers, standard rates. A person with a BMI of 32, treated hypertension and borderline blood sugar may be rated more heavily, even though the build number is lower. A clean paramedical is your strongest asset.
Weight loss, surgery and being underweight
Underwriters are cautious about weight that has only just come off, because the data shows it often returns. Two common practices:
The add-back rule. If you have lost weight in the last twelve months, many insurers will credit only part of it, commonly around half, when placing you on the build table. Lose 40 lb this year and you may be assessed as if you had lost 20. Weight that has been stable for a year or more is credited in full. This is not a reason to delay applying; it is a reason to apply, get covered, and request a reconsideration once the loss has held for a year.
Bariatric surgery. After gastric bypass, sleeve or banding, insurers typically postpone for six to twelve months. They want to see that weight has stabilized, that there have been no surgical complications, and that nutritional markers are in range. Once that period has passed, many applicants are assessed at their new weight, and improvements in blood pressure and blood sugar frequently move them into a better class than they had before surgery.
Weight-loss medications. Newer prescription medications for weight management are increasingly common on applications. Insurers are still settling their approach, but in general the underwriter will want to know why it was prescribed, how long you have been on it, and whether weight has stabilized. Disclose it; the prescription record will show it anyway.
Being underweight
Less discussed but real: a very low BMI can also draw a rating or a request for more information. Underwriters associate low weight with eating disorders, undiagnosed illness, chronic conditions and, in older applicants, frailty. If you are naturally slim and healthy, a normal paramedical will usually settle it. If there is a medical reason for low weight, expect the underwriter to ask about it.
Preferred rates: the cost you do not see
Even when a higher build does not trigger a rating, it can cost you a discount. Preferred and preferred plus classes typically require a build well inside the standard limits, along with good blood pressure, cholesterol and no tobacco. The difference between preferred plus and standard can be 20–35% on the premium at some insurers.
So if you are at a BMI of 29 and expecting the best possible rate, the honest answer is that you will probably be approved at standard, a perfectly good outcome, but the top-tier discount is likely off the table until your build is lower.
What a rating actually costs
For a healthy non-smoker, indicative monthly premiums for $500,000 of 20-year term life insurance are roughly $32–$48 at age 40. That is an illustrative range, not a quote; age, health, smoking status, coverage amount and insurer all change the number. See our guide to life insurance rates at age 40 for the surrounding detail and life insurance costs in Ontario for the broader picture.
The table shows how a build rating changes that number. Illustrative only.
| Result | Indicative monthly premium, age 40 non-smoker, $500K 20-year term |
|---|---|
| Preferred plus (build well within limits) | roughly $26–$38 |
| Standard | roughly $32–$48 |
| Rated +50% | roughly $48–$72 |
| Rated +100% | roughly $64–$96 |
| Rated +150% | roughly $80–$120 |
Two ways to soften a rating. First, term lengths and coverage amounts can be adjusted; a rated $500,000 10-year policy may fit the budget where a rated 20-year does not, and can be re-shopped later. Second, most insurers will reconsider a build rating on request after weight has been stable at a lower level for a year or more.
Practical steps before you apply
- Know your numbers. Weigh yourself, and if you have recent blood pressure and blood work from your doctor, have them handy. Surprises at the paramedical are what cause delays and disappointing offers.
- Do not guess low. The nurse will weigh you for fully underwritten coverage, and an application that says 210 when the scale says 240 undermines the rest of your file.
- Schedule the paramedical well. Morning, fasting if asked, no heavy exercise the day before, and no alcohol the night before, so blood pressure and liver enzymes read normally.
- Mention muscle mass if it applies. Some insurers will use waist circumference or body-fat measurement as an alternative for athletic builds.
- Get treated conditions documented. If your blood pressure is controlled on medication or your apnea is managed on CPAP, bring the evidence; controlled conditions are assessed far better than unknown ones.
- Use a broker. Build tables differ more between insurers than almost any other underwriting factor. A broker can check your height and weight against several tables before you apply anywhere.
If you are declined or heavily rated
A decline for build from one insurer is worth a second opinion, because the tables genuinely vary. If traditional coverage is not available right now, simplified issue life insurance asks a short list of health questions and many simplified products either do not ask about weight or use a generous table. Amounts are smaller and premiums higher per dollar, but it is real coverage. For the hardest cases, guaranteed issue life insurance asks no health questions at all, with correspondingly small amounts and a waiting period.
Employer group coverage is issued without individual underwriting up to a set amount and is worth maximizing while you sort out an individual policy.

Frequently asked questions
What BMI is too high for life insurance in Canada?
There is no single cut-off. Most insurers approve standard rates into the low 30s, apply ratings through the mid-to-high 30s, and become more restrictive above 40, particularly if there are related conditions. Some companies are noticeably more generous than others at the same height and weight, so a decline or heavy rating at one insurer does not mean the same result everywhere.
Do life insurance companies actually weigh you?
For fully underwritten policies above a certain amount, a paramedical nurse visits and records your height and weight along with blood pressure and samples, so yes. For smaller amounts and simplified issue policies, you self-report on the application. Misstating your weight is a form of misrepresentation that can void a policy in the first two years, so be accurate.
Will I get a better rate if I lose weight before applying?
Possibly, but underwriters discount recent losses. A common approach is to add back roughly half of any weight lost in the last twelve months, on the basis that it may return. Weight that has been stable for a year or more is credited in full. If you are partway through a planned weight loss, applying now and asking for a reconsideration later is often the better approach than waiting uninsured.
Can I get life insurance after bariatric surgery?
Yes, but usually after a waiting period. Insurers commonly postpone for six to twelve months after gastric bypass or sleeve surgery to see that weight has stabilized and there are no complications. After that, many applicants are assessed at their new weight, and improvements in blood pressure or blood sugar can move them into a better class than before surgery.
