Canadian Dental Care Plan Eligibility: Who Qualifies and Why Work Benefits Matter

Current as of October 2026. Government programs, tax rules and prices change. Check the official sources listed at the end of this page before making a decision, and confirm details with a licensed advisor.

The four CDCP eligibility criteria at a glance

As of October 2026, the Government of Canada says you must meet all four of its eligibility requirements to qualify for the Canadian Dental Care Plan. Missing any one of them means you cannot join, even if you meet the other three. If you want the bigger picture on what the plan covers and how it works day to day, start with our overview of the Canadian Dental Care Plan.

Here is the short version of the four criteria, as published on Canada.ca:

• No access to dental insurance or coverage through work, a pension, a family member's work or pension plan, a professional or student organization, or a plan you buy yourself.
• A filed Canadian tax return for the previous year, for you and, if you have one, your spouse or common-law partner.
• Adjusted family net income under $90,000.
• Canadian residency for tax purposes, for you and your spouse or common-law partner.

The access to dental insurance test, explained

This is the rule that trips people up most often, and it is the one that connects directly to the workplace. As of October 2026, Canada.ca states that you are not eligible if you have access to dental insurance or coverage through your own work or pension plan, a family member's work or pension plan, a professional or student organization, or insurance you purchased yourself, including supplementary or top-up coverage. A health spending account that can be used for dental costs also counts as access.

The key word is access, not use. According to the federal rules, you are considered to have access even if you have never used the coverage, chose not to enrol, would have to pay premiums for it, or find that it does not cover the full cost of your care. In plain terms: if dental coverage was offered to you, the CDCP generally treats you as having it.

There are a few important nuances published by the government:

• Government social programs do not disqualify you. Canada.ca says that if you have dental coverage through a provincial, territorial or federal government social program, you could still qualify for the CDCP. A provincial program such as Healthy Smiles Ontario is a government program rather than private insurance, but confirm your situation with Service Canada.
• Some retirees have an exception. Retired people who opted out of dental coverage through their pension before December 11, 2023, and cannot opt back in, may still qualify.
• Partial coverage still counts. A plan that only pays part of a cleaning or caps out quickly is still access to dental coverage under the rules.

How the $90,000 income threshold works

As of October 2026, your adjusted family net income must be less than $90,000. This is a family figure, so it combines your net income with your spouse's or common-law partner's. Canada.ca describes the calculation as starting from family net income (line 23600 of the tax return), subtracting any Universal Child Care Benefit and Registered Disability Savings Plan income reported, and adding back certain amounts repaid. That is why filing a tax return every year matters so much: without it, the government cannot assess your income.

Income also affects how much the plan pays. As of October 2026, the federal coverage page sets out three levels of co-payment based on adjusted family net income:

• Under $70,000: the CDCP covers 100% of eligible costs at its established fees.
• $70,000 to $79,999: the CDCP covers 60% of eligible costs.
• $80,000 to $89,999: the CDCP covers 40% of eligible costs.

Applying, renewing and staying eligible

As of October 2026, Canada.ca says applications are open for the 2026 to 2027 benefit period, and you can apply online through My Service Canada Account, online through Canada.ca, or by phone. Dependants can be included on an application, but a spouse or common-law partner must submit their own application to be covered.

Eligibility is not a one-time check. The government states that each benefit period ends on June 30 and that members must renew every year, confirming their information and their dental coverage situation. Both the member and their spouse need to have filed their taxes for the previous year and received a notice of assessment.

The government also runs member eligibility reviews that compare the information in an application with the T4 or T4A slips reported for the member and their spouse or common-law partner. If a review finds that someone had access to dental insurance, Canada.ca says they may have to reimburse the Government of Canada for services the plan paid while they were ineligible, and cannot reapply until the amount owed is fully repaid. Anyone whose job situation changes, for example starting a new role that offers a group dental plan, should check their eligibility rather than assume it carries over.

What employers need to know: the T4 box 45 code

Since the Dental Care Measures Act came into force in 2023, employers and pension plan administrators have been required to report whether they offer dental coverage. As of October 2026, this appears in box 45 of the T4 slip for employees, and box 015 of the T4A slip for pensioners when there is an amount in box 016. According to the CRA, box 45 is mandatory on T4 slips for 2023 and later, and it reflects whether the employee or their family members were eligible to access dental coverage on December 31 of the year. If you do not offer dental coverage, you still complete it, using code 1.

The government publishes five codes:

• Code 1: not offered access to any kind of dental insurance or coverage.
• Code 2: employee or pensioner only.
• Code 3: employee or pensioner, their spouse or common-law partner, and dependent children.
• Code 4: employee or pensioner and their spouse or common-law partner.
• Code 5: employee or pensioner and their dependent children.

How employers and employees should think about the CDCP

For employers, the practical takeaway is that the CDCP is not a substitute you can lean on while also offering a dental plan. Once you offer dental coverage, or a health spending account that pays dental expenses, your employees (and often their families) generally have access under the federal rules, even if some of them waive the benefit. Getting box 45 right on every T4 protects your team from surprise eligibility reviews down the road.

For many small businesses, the more useful question is what your people actually need. The CDCP is income tested and pays at its own established fees, so members may owe extra if a clinic charges more than the plan reimburses. A group plan, by contrast, can be designed around your workforce: the twice-yearly cleaning, the cracked filling, a child's checkup, maybe orthodontics. An advisor can walk you through how a plan's design and cost trade off, and how offering coverage interacts with government programs your employees might otherwise use.

For employees, the simplest check is your most recent T4: a code of 2, 3, 4 or 5 in box 45 means your employer reported offering you dental coverage. If you are unsure, ask HR before you apply. If you are an employer weighing whether to add dental coverage, or wondering how your current plan compares, you can get matched with a licensed benefits advisor who can explain your options.

Common questions

Can I qualify for the CDCP if I turned down my employer's dental plan?

Generally no. As of October 2026, Canada.ca says you are considered to have access to dental insurance even if you chose not to enrol, never used it, or would have to pay premiums. Declining the coverage does not change that.

Does a health spending account count as dental insurance for the CDCP?

Yes, if it can be used for dental costs. As of October 2026, the federal eligibility page lists health spending accounts covering dental costs as a form of access that makes you ineligible.

What is the income limit for the Canadian Dental Care Plan?

As of October 2026, your adjusted family net income must be less than $90,000. Families with income from $70,000 to $89,999 can still qualify but pay a co-payment on eligible services.

Does Healthy Smiles Ontario or another government program disqualify me?

Generally no. As of October 2026, Canada.ca states that people with dental coverage through a provincial, territorial or federal government social program could still qualify for the CDCP, as long as they meet the other criteria.

What happens if I join the CDCP and later get dental benefits at work?

Your eligibility can change. Members must renew yearly, and the government reviews eligibility against T4 and T4A slips. As of October 2026, the government says ineligible members may have to repay services paid while they were ineligible, so update your information when your coverage changes.
