Use it or lose it: checking health and dental benefits before December 31
Most employer health and dental plans in Canada run on the calendar year, which means the annual maximum you have not used by December 31 does not roll over — it evaporates, and a fresh deductible starts in January. Canadian dental guidance puts typical annual maximums around $1,000 to $2,500 depending on the plan, and every fall the same pattern repeats: unused cleanings, an unfinished crown, a vision allowance never spent, and then a December scramble for appointments that no longer exist. October and November are when this is fixable calmly. This guide explains what actually expires, what does not, and the order to book things in so the value you have already paid for — through premiums and payroll deductions — gets used.
What expires, what resets, and what does neither
| Benefit element | Typical year-end behaviour | Your move |
|---|---|---|
| Dental annual maximum | Unused portion is lost; the maximum resets January 1 (commonly $1,000–$2,500) | Book outstanding treatment — fillings, the second half of a crown, periodontal work — early enough to complete it, not just start it |
| Deductible already met | Resets in January; treatment done this year after the deductible is met costs you only the co-insurance share | A met deductible is a discount with an expiry date — another reason unfinished treatment belongs in this year |
| Preventive allowances (cleanings, exams, X-rays) | Often covered at or near 100 percent, a set number per year, unused visits do not accumulate | If a cleaning is outstanding, book it now; December hygiene schedules fill first |
| Vision allowance | Typically a fixed amount per period (often 12 or 24 months — check which yours is) for glasses or contacts | Confirm the period end; a 24-month allowance expiring in February should not be panic-spent in December |
| Paramedical maximums (physio, massage, etc.) | Per-service annual maximums usually reset with the plan year | Use remaining amounts for care you genuinely need; booking treatment you do not need solely to spend a maximum helps no one, including you |
| Health spending account (HSA) | Varies: some forfeit at year-end, some allow a carry-forward of unused balances or a claims grace period | Read your plan's exact rule — the difference between forfeit and carry-forward is the whole decision |
| Orthodontic lifetime maximum | Lifetime, not annual — it does not expire at year-end | No December rush; starting earlier still starts the plan's payments earlier |
Two warnings belong on top of the table. Not every plan uses the calendar year — some run on an anniversary or school year — so the first task is confirming your plan's year and reset dates in the benefits portal rather than assuming December 31. And coverage percentages differ by category in most plans: basic and preventive care is commonly covered at a higher percentage (often 80–100 percent) than major restorative work (often around 50 percent), so the out-of-pocket estimate for that crown should come from a pre-determination, not from optimism.
The autumn procedure
- Pull your real numbers. Log into the benefits portal and record, per family member: remaining dental maximum, deductible status, preventive visits used, vision allowance and its period end, paramedical balances, and any HSA balance with its forfeiture or carry-forward rule. Screenshot it; this page is the plan.
- List unfinished business. Ask your dentist's office what treatment is on file as recommended-but-unscheduled for everyone on the plan. This list — not the maximum — is what the remaining weeks are for.
- Get a pre-determination for anything major. For crowns and other major work, have the office submit the estimate to the insurer and confirm coverage and your share before booking. Two-stage treatments need both appointments inside the year for the year's maximum to apply as expected — confirm how your plan treats treatment spanning the reset.
- Book in scarcity order. Hygiene and dental surgery slots disappear first, then specialist appointments, then optical and paramedical. Book the constrained ones in October even for December dates.
- Spend the HSA last and deliberately. If your spending account forfeits, eligible expenses you would pay anyway — including, in some plans, the employee share of health and dental premiums or the co-insurance the main plan did not cover — are the honest way to use a balance. Check your plan's eligible-expense list and claim-submission grace period before assuming a December 31 service date is a December 31 claim deadline; many plans allow claims to be submitted weeks into the new year for prior-year expenses.
- Keep every receipt and explanation-of-benefits statement. Year-end is also when duplicate claims, misapplied maximums and coordination-of-benefits errors surface — a spouse's plan may cover part of what yours did not, and none of that can be reconstructed in February from memory.
What success looks like by mid-December: every genuinely needed treatment completed or firmly booked inside the year, remaining maximums spent only on care that was actually warranted, claims submitted with receipts kept, and a note in next year's calendar for early October — because the entire exercise is easier as an autumn routine than as a December emergency.
Two family situations worth handling deliberately
Families with two working partners hold an advantage that expires on the same schedule: coordination between two plans can cover a large treatment more completely than either plan alone, but only when claims are submitted in the correct order with the first plan's statement attached — paperwork that is far easier to assemble in November than to reconstruct in February. The second situation is the family member mid-treatment when the year turns: orthodontics, periodontal programs and multi-stage dental work all span the reset, and plans differ in whether the year's maximum that applies is the one in force when treatment started or when each stage completes. Ask the insurer that question in writing before the second stage is booked; the answer is worth real money and cannot be negotiated afterward.
FAQ
Both my partner and I have plans. Does order matter? Yes — coordination of benefits decides which plan pays first (typically the plan of the person receiving care is primary for their own claims, with specific rules for children's claims). Submitting to the primary plan first, then sending the remaining balance to the secondary plan with the first plan's statement, is how families legitimately recover more of a bill — and it only works with both plans' documents kept.
Should I book treatment I do not need to "use the money"? No. Benefits are insurance, not a gift card; unnecessary treatment carries real cost in time, discomfort and risk, and premiums fund the pool everyone draws on. The goal of this guide is narrower: stop paying for needed care twice — once in premiums, once out of pocket in January.
My plan year is not the calendar year. Does any of this apply? All of it, shifted to your plan's reset date. The procedure is identical; only the deadline moves, which is why step one is confirming your own plan year.
