20, 25 or 30 years: choosing a term that fits your mortgage

Two clocks, often confused

Almost every conversation about this starts with the same mix-up, so it is worth clearing first.

The Financial Consumer Agency of Canada draws the line cleanly: the mortgage term is the time your mortgage contract is in effect, and the amortization period is the time it takes to pay your mortgage. Terms in Canada may range from a few months to five years or more, and at the end of each one you renew. Amortization runs much longer.

So when someone says "my mortgage is five years," they are describing the contract, not the debt. Sizing a life insurance term against that five year figure would leave the household uncovered for the two decades that follow.

How long the amortization can actually run

This is where a lot of advice is half-told, and the half that gets left out matters.

If your down payment is less than 20% of the price, the mortgage is insured and the agency sets out the ceiling: 30 years if you are a first-time buyer or buying a new build, and 25 years in all other cases. If your down payment is 20% or more, the agency is equally clear that your lender sets your maximum amortization period. In practice that means 30-year amortizations are widely available on uninsured mortgages, and some lenders go further.

So do not assume 25 years. Look at the number on your own mortgage documents, because that is the one your insurance term should be measured against.

Measure against the years of exposure

The useful question is not how long the mortgage lasts. It is how long your family would be in trouble if one income disappeared.

For most households two things drive that answer. The first is the amortization period, because that is genuinely how long the payments run. The second is your children, because the years when they are at home and dependent are the years when the loss of an income does the most damage.

Take the larger of the two and round up to the term lengths insurers actually sell. That usually produces 20, 25 or 30.

What each length tends to suit

20 years. The common choice for buyers in their late 30s and 40s. It carries you through the bulk of the amortization and through the school years, and it is the least expensive of the three. If your youngest will be independent inside 20 years and your amortization is close to done, this is often enough.

25 years. The natural fit when the amortization is 25 years and you are buying at or near the start of it. It matches the debt almost exactly and costs modestly more than 20.

30 years. Suits younger buyers, 30-year amortizations, and anyone with very young children. It is the most expensive of the three per month, but it is bought at your current age, which is the youngest you will ever be. For a buyer in their early 30s the extra years are cheaper now than a new policy would be later.

What happens when the term ends

A term policy expires, and the plan should include that date rather than arrive at it.

A 20-year policy bought at 35 ends at 55. Three things are usually available at that point. The policy can renew without new medical questions at a premium set on your age then, which is a large step up. You can convert it to permanent coverage, again without new medical questions, as long as you are still inside the conversion age limit in your contract. Or you can let it end because the mortgage is gone and the children are grown, which is the outcome most households are actually buying towards.

The conversion deadline is the one to write down. It is an age, not a number of years, it varies by insurer, and it often falls somewhere between 65 and 71. If your health changes at 50 and the privilege has already closed, the options narrow.

Why the length changes the price

A longer term costs more than a shorter one for the same amount of coverage, because the insurer is carrying the risk for more years and you are older during the later ones. The other inputs, including age, sex, health and nicotine, are covered in how prices are set.

What people underestimate is the cost of the alternative. The agency points out that with term insurance your premiums may increase when the policy renews, and by then you are 20 years older. Buying a shorter term to save a few dollars a month and then buying again in your mid-50s is usually the more expensive path.

The clause worth checking

Conversion. A convertible policy lets you swap into permanent coverage, up to an age set by the insurer, without answering new medical questions. That is the safety valve if your health changes and you still need coverage when the term ends, and the age limit is the part to compare between contracts.

Renewability is worth knowing about but is not much of a shopping decision: individual term policies sold in Canada are generally renewable at a stated, much higher premium. Ask what the renewal premiums are rather than whether the feature exists.

Where the bank's coverage sits in this

Creditor insurance attached to a mortgage does not have a term you choose. It runs with the mortgage, and the agency notes that eligibility usually has a maximum age, often between 65 and 70. The length is decided by the loan and by the certificate rather than by your family's situation, and the amount falls the whole way through. The full comparison walks through what that means over a typical amortization.

What this means for you

Ignore the number on your mortgage renewal letter when you are choosing an insurance term. Use the amortization period on your own documents and the age of your youngest child, take the larger, and round up.

Then price two options rather than one. Seeing 20 and 30 years side by side makes the decision a choice rather than a guess. You can see estimates for different terms in about two minutes, and if you want a second opinion on which one fits your household, that is exactly the sort of thing a licensed advisor is for.
