How to Renew Your CDCP Coverage: A Plain-English Guide for Langley Patients
If your CDCP coverage is expiring, here’s the short version: renewal is not automatic, and you have to do it every year. The Canadian Dental Care Plan (CDCP) covers a single benefit period that ends each June 30, and you must confirm you still qualify before the next period begins — or your card stops working at the dental office.
The good news: renewing is quick once you know the steps. This plain-English guide walks Langley patients through exactly how to renew, what to have ready, and what to do if you’ve already missed this year’s deadline.
How to Renew Your CDCP Coverage in 4 Steps
- Know your renewal window. CDCP coverage ends June 30 each year. Renewal opens in the spring — for the 2026–2027 benefit year it ran from April 15 to June 1, 2026. Don’t wait for a letter; mark the spring window on your calendar.
- Gather what you need. Your CDCP member ID, Social Insurance Number, date of birth, current home/mailing address, and a filed tax return with Notice of Assessment for you and your spouse or common-law partner.
- Confirm you still qualify. You must have no access to private or employer/pension dental insurance, an adjusted family net income under $90,000, filed taxes for the previous year, and be a Canadian resident for tax purposes.
- Renew through My Service Canada Account. Log in, confirm or update your details, and re-attest that you still meet the requirements. Renewal usually takes under 15 minutes. Then check your renewal status before booking dental care.
Already missed the deadline? If you had coverage for 2025–2026 and didn’t renew by June 1, 2026, you can submit a new application for the 2026–2027 benefit year now — but there may be a gap in your coverage until it’s approved, and any dental care you receive during that gap won’t be covered or reimbursed retroactively. The next renewal period, for 2027–2028, opens in spring 2027.
Why Does CDCP Require Annual Renewal?
The program renews yearly because the federal government re-confirms that you still meet the eligibility criteria. Specifically, they re-check:
- Income — your adjusted family net income must still be under $90,000/year, based on your most recently filed tax return
- Insurance status — you must still have no access to private, employer, or pension dental insurance (this applies even if you’d have to pay a premium, choose not to use it, or previously opted out)
- Residency and tax filing — you must be a Canadian resident for tax purposes and have filed your taxes for the previous year
Because people’s circumstances change — new jobs, new employer benefits, changes in household income — the annual check ensures CDCP benefits go to those who continue to need them.
When Does CDCP Coverage Expire?
Every CDCP member’s coverage now runs on a standard benefit period that ends June 30. Renewal happens during a defined season in the spring rather than on a date tied to when you first enrolled. For the 2026–2027 year, that season ran April 15 to June 1, 2026.
Important: the government uses the contact information from your Canada Revenue Agency (CRA) account. If your address has changed and your CRA account hasn’t been updated, important notices may never reach you. Check your CRA My Account to confirm your details are current well before the spring renewal window opens.
How to Complete Your CDCP Renewal
The fastest and most reliable way to renew is online:
Online through My Service Canada Account (recommended)
Log in at canada.ca, open your CDCP page, confirm or update your information, and re-attest your eligibility. Confirmation is usually near-instant.
By phone
If you can’t renew online, call Service Canada to complete your renewal. For questions about your existing coverage or claims, Sun Life (the CDCP benefits administrator) can be reached at 1-888-225-0709, Monday to Friday. Have your member ID and SIN ready.
Renewal is not automatic — you must actively complete it each year, even if nothing in your situation has changed.
Beware of CDCP Renewal Scams
The CDCP will never ask you to pay to apply or renew. Be cautious of mail, phone calls, texts, emails, ads, or pop-ups asking for payment or for your banking or credit card details. Only renew through official Government of Canada channels (canada.ca and My Service Canada Account). If a message seems suspicious, don’t click — go directly to canada.ca instead.
What If Your Situation Changed Since You First Applied?
Life changes can affect your CDCP eligibility. Here’s what to know for the most common scenarios:
You started a new job with dental benefits
If your employer now offers dental coverage — even if you haven’t enrolled, don’t use it, or have to pay a premium — you are no longer eligible for CDCP. Check box 45 on your T4 (or box 015 on a T4A pension slip): a code of 2, 3, 4, or 5 means you have access to dental insurance.
Your household income went up
If your combined adjusted family net income crossed above $90,000, you’ll no longer qualify. If it shifted between brackets, your co-pay level adjusts automatically based on your tax return — you don’t need to report it separately.
Your income went down
This works in your favour. A lower income bracket can reduce your co-pay at renewal — or you may now qualify if you were previously just over the $90,000 threshold.
You got married or had a family member move in
Combined household income determines your co-pay, so a change in household composition may change the income bracket applied to your account.
You moved within Langley or to a new city
Moving within Canada doesn’t affect eligibility, but update your CRA address right away so notices reach you. Moving outside Canada would affect residency eligibility.
What Happens If You Miss the Renewal Deadline?
If your CDCP coverage lapses because you didn’t renew in time:
- Your member card stops being accepted at dental offices
- Any dental work billed to an expired account will be rejected
- You can submit a new application, but there may be a coverage gap — and care received during the gap is not reimbursed retroactively
To avoid gaps, set a reminder for early spring each year and renew as soon as the window opens. Don’t rely solely on a notice arriving in the mail.
Tips to Keep Your CDCP Coverage Uninterrupted
- File your taxes on time — renewal is tied to your most recent Notice of Assessment. If you haven’t filed, your renewal can be delayed.
- Update your CRA contact info every time you move — that’s where your mailing address is pulled from.
- Renew early in the spring window — log into My Service Canada Account as soon as renewals open rather than waiting until the deadline.
- Confirm your dates — your coverage runs to June 30; check My Service Canada Account if you’re unsure of your status.

Frequently Asked Questions
Does CDCP renew automatically?
No. CDCP renewal is not automatic. Even if your income, insurance status, and address are unchanged, you must actively renew each year — usually through My Service Canada Account — to confirm you still meet the eligibility requirements. If you don’t renew, your coverage ends.
When does CDCP coverage expire?
CDCP coverage runs on a benefit period that ends June 30 each year. You renew during a spring renewal season; for the 2026–2027 year it ran from April 15 to June 1, 2026. The next renewal period, for 2027–2028, opens in spring 2027.
What happens if I miss the CDCP renewal deadline?
Your coverage lapses and your member card stops being accepted at dental offices. You can submit a new application for the current benefit year, but there may be a gap in coverage until it’s approved — and any dental care received during that gap is not covered or reimbursed retroactively.
Can my dentist help with CDCP renewal?
Your dentist can’t renew your coverage for you — renewal is done through Service Canada — but the team at North Langley Family Dental can confirm whether your CDCP coverage is currently active before your appointment and explain what your plan covers. Renewing itself must be completed through My Service Canada Account or by phone with Service Canada.
How do I check when my CDCP coverage expires?
Your coverage period ends June 30, and you can confirm your exact status and renewal details through your My Service Canada Account. You can also call Sun Life’s CDCP member line at 1-888-225-0709 to confirm your current coverage.
