Short Answer
The best time to buy life insurance is before you need it — specifically, when you are young and healthy and have someone who would be financially harmed by your death. Waiting costs more every year and risks a health event that makes coverage unavailable or expensive.
Life Stage Guide: When Coverage Is Most Critical
| Life stage | Coverage need | Priority |
|---|---|---|
| Single, no dependents, no co-signed debt | Low — no one depends on your income | Optional |
| In a relationship, no children, shared mortgage | Moderate — partner relies on your income contribution | Consider |
| Partner / children / mortgage | High — peak need | Buy now |
| Children approaching independence, mortgage shrinking | Moderate — need declining | Review and right-size |
| Children independent, mortgage paid, assets accumulated | Low to none | Reassess |
| Retired, debt-free, assets sufficient for survivor | Minimal | Consider letting lapse or maintaining minimal coverage |
The Cost of Waiting: Premiums by Age
Approximate monthly cost for $1,000,000 of 20-year term, non-smoker:
| Age at purchase | Approximate male premium | Approximate female premium |
|---|---|---|
| 25 | $38–$50/month | $30–$40/month |
| 30 | $50–$65/month | $40–$52/month |
| 35 | $72–$90/month | $57–$72/month |
| 40 | $120–$155/month | $95–$120/month |
| 45 | $200–$260/month | $160–$205/month |
| 50 | $340–$430/month | $270–$345/month |
Approximate ranges — varies by insurer and health class. Smokers pay 2–3x non-smoker rates.
Waiting from 30 to 40 nearly doubles the monthly cost. Over a 20-year term, that difference adds up to $15,000–$25,000 in extra premiums.
Key Trigger Events: When to Buy or Reassess
| Trigger event | Action |
|---|---|
| Getting married or moving in with a long-term partner | Buy if not already covered — partner depends on your income |
| First pregnancy | Buy before birth — secure at pre-pregnancy health status |
| Taking on a mortgage | Coverage amount should account for mortgage balance |
| Having a second or third child | Review coverage amount — obligations have grown |
| Income increase | Coverage amount should grow with income to replace |
| Starting a business | Business partner protection, key person, or personal coverage |
| Death of a spouse | Review own coverage needs independently |
| Divorce | Remove former spouse as beneficiary; reassess coverage need |
| Child becomes financially independent | Total need decreases — review coverage |
| Mortgage payoff | One major obligation eliminated — coverage may be reducible |
How Much Coverage Do You Need?
| Quick calculation | How |
|---|---|
| Income replacement | Annual income × 10–12 |
| DIME method | Debts + Income years needed + Mortgage + Education funding goals |
| Subtract existing assets | Savings, investments, existing group coverage |
| = Coverage gap to buy |
Example: $100,000 income × 10 = $1,000,000. Minus $200,000 in savings and $200,000 in group coverage = $600,000 to purchase individually.
What Happens If You Wait and Your Health Changes
| Health event | Impact on future insurability |
|---|---|
| Type 2 diabetes diagnosis | Rated policy (higher premium) or exclusions |
| Heart condition | May be declined or heavily rated |
| Cancer diagnosis | Likely declined for new coverage |
| Mental health treatment | Can affect premium class depending on severity and recency |
| Sleep apnea with treatment | Often still insurable; minor impact |
Once you are medically declined, privately purchased life insurance becomes difficult or impossible to obtain through normal channels. Group insurance through an employer (if you join one after) may provide limited guaranteed coverage regardless of health — but it is not portable.
When You Probably Don’t Need Life Insurance Anymore
| Criteria | Suggests coverage may be unnecessary |
|---|---|
| Children are fully independent adults | Peak dependency period is over |
| Mortgage is paid off | Largest co-signed obligation is gone |
| Savings and investments can support surviving spouse | Self-funded survivor income |
| No co-signed business debts | No business liability to transfer |
| Near or in retirement with pension income | Replacement income already structured |
Many Canadians approaching 60 find their need has largely passed, particularly if they have accumulated significant assets and their term policy is expiring anyway.
Bottom Line
The right time to buy life insurance is as early as your situation creates a dependency — a partner, a child, a mortgage, or a business partnership. Locking in rates while young and healthy is the single biggest financial lever in life insurance decisions. Every year you wait costs more and every unanticipated health event makes coverage harder to get.
