If you’re considering offering group health and dental benefits to your employees, you may be surprised to learn that many group benefits plans require mandatory participation.

For small-business owners in Alberta, this can raise important questions. Why can’t employees simply choose whether they want coverage? Can an employer offer benefits to only certain employees? What happens when someone already has coverage through a spouse?

Understanding mandatory participation can help you choose the right employee benefits plan, avoid enrollment issues and ensure your business follows the applicable plan requirements.

What Is Mandatory Participation in Employee Benefits?

Mandatory participation generally means that all employees who meet the plan’s eligibility requirements must be enrolled in the applicable benefits coverage, unless a permitted exception applies.

For example, if your business offers a group health and dental plan to eligible full-time employees, you generally cannot allow some employees to participate while excluding others simply because they do not want the coverage.

The exact requirements depend on the insurer, the contract, the employee’s eligibility and the type of benefits being offered.

Mandatory participation is common in traditional group insurance arrangements because it helps ensure that the plan covers a reasonably broad cross-section of eligible employees.

1. It Helps Spread the Insurance Risk

One of the biggest reasons group benefits plans require participation is to spread risk across a group of employees.

Insurance works by collecting premiums from a group of insured members to help pay eligible claims. Not everyone will use the same amount of coverage in a given year.

Some employees may have very few claims, while others may need expensive prescription medications, dental treatment, paramedical services or other eligible healthcare expenses.

When participation is voluntary, employees who expect to use more benefits may be more likely to enrol, while healthier employees may choose to opt out. This can create an imbalance between the premiums collected and the claims paid.

Mandatory participation helps reduce this selection risk by encouraging broader participation among eligible employees.

Why does this matter? A more balanced insured group can support the sustainability and pricing of the benefits plan over time, although it does not guarantee stable premiums or prevent renewal increases.

2. It Helps Keep Premiums More Affordable

Group insurance pricing depends on several factors, including the number of insured employees, demographics, coverage levels, claims experience and the insurer’s pricing methodology.

If participation is optional, the people most likely to need coverage may be disproportionately represented in the insured group.

This can make it more difficult for insurers to price the plan sustainably.

By requiring eligible employees to participate, insurers can spread costs across a broader group rather than relying only on employees who actively choose to enrol.

For small businesses with only two to ten employees, this principle can be especially important. A small group has fewer members across whom claims risk can be distributed.

Mandatory participation does not mean every employee must receive identical coverage or that premiums cannot increase. It helps establish the participation conditions under which the insurer agrees to provide coverage.

3. It Promotes Fairness Among Employees

Mandatory participation can also help employers maintain a consistent benefits offering.

Imagine a business with six eligible employees. Three employees enrol in the health and dental plan, while the other three decline because they believe they will not need coverage.

The employees who enrol may receive valuable protection against eligible healthcare expenses, while those who decline may face significant out-of-pocket costs if their circumstances change.

A mandatory plan helps establish a consistent approach to coverage for eligible employees.

It can also support an employer’s overall compensation strategy by making group benefits part of the employment package rather than an optional perk available only to employees who choose to participate.

However, employers should apply eligibility rules consistently and follow the applicable employment agreements, insurer requirements and legal obligations.

4. What If an Employee Already Has Coverage Through Their Spouse?

This is one of the most common questions employers have about mandatory participation.

An employee may already have health and dental coverage through a spouse or partner’s employer-sponsored benefits plan. They may reasonably wonder why they need another plan.

The answer depends on the insurer’s rules and the coverage involved.

Health and dental coverage: Some plans allow an employee to waive all or part of their own coverage when they have proof of comparable coverage elsewhere. Other plans may have different requirements.

Where a waiver is permitted, the employee may need to provide evidence of the other coverage and complete the required paperwork.

Life insurance and disability benefits: These benefits are generally treated differently from health and dental coverage. Having coverage through a spouse does not necessarily allow an employee to waive their own life or disability benefits.

An employer should never assume that an employee can opt out simply because they have benefits elsewhere. Confirm the applicable insurer’s rules before making an enrollment decision.

5. Can Employees Opt Out of a Group Benefits Plan?

Sometimes, but it depends on the plan.

The following examples illustrate how participation requirements may work:

Situation	What may apply
An eligible employee does not want benefits	They may be required to enrol under the plan’s participation rules.
An employee has health and dental coverage through a spouse	A waiver may be permitted if the insurer’s rules allow it and the required proof is provided.
An employee has no other coverage	They may be required to enrol if they meet the plan’s eligibility requirements.
An employee works part-time	Eligibility depends on the plan’s definitions, minimum hours and other requirements.
An employee declines life or disability coverage	A separate waiver may not be permitted, even if they have coverage through a spouse.

These are general examples rather than universal rules. The governing contract and applicable requirements determine the actual outcome.

6. Why Can’t an Employer Offer Benefits Only to Employees Who Want Them?

Employers sometimes assume they can make a group benefits plan available only to employees who express interest.

However, group insurance contracts commonly establish minimum participation requirements and eligibility rules that the employer must follow.

Allowing employees to select themselves into coverage without meeting those requirements can undermine the insurer’s ability to spread risk across the group.

It can also create administrative problems, inconsistent treatment of employees and uncertainty about who is eligible for coverage.

Before implementing a benefits plan, employers should establish which employees are eligible, what participation is required and which exceptions are permitted.

An employer should not promise that employees can opt out until the insurer has confirmed the applicable rules.

7. What Does Mandatory Participation Mean for Small Businesses in Alberta?

For a small business with two or more employees, understanding participation requirements is an important part of choosing a group benefits plan.

Before requesting a quote, consider the following:

• Identify eligible employees. Determine who meets the insurer’s requirements for employment status, minimum hours and any applicable waiting period.
• Understand the participation rules. Ask whether all eligible employees must enrol and whether a minimum percentage of employees must participate.
• Confirm waiver provisions. Find out whether employees with coverage through a spouse can decline health and dental coverage and what proof is required.
• Budget for employer contributions. Decide how much the business will pay toward employee premiums and what employees will contribute, subject to applicable requirements.
• Prepare accurate enrollment information. Employee details and waiver documentation help the insurer determine eligibility and process enrollment correctly.

For example, if your business has five eligible employees but only two want benefits, the insurer may not permit the plan to proceed on that basis. The outcome depends on the plan’s minimum participation requirements and any permitted exceptions.

Discuss these details before selecting a plan to avoid surprises during enrollment.

The Bottom Line: Mandatory Participation Helps Make Group Insurance Work

Mandatory participation is a common feature of group benefits plans because it helps spread insurance risk, supports sustainable pricing and encourages consistent coverage among eligible employees.

Although some employees may be able to waive specific benefits when they have other coverage, opting out is not always permitted. The rules can differ between health and dental, life insurance and disability benefits.

For employers, the best approach is to understand the insurer’s requirements before offering coverage and communicate the rules clearly to employees.
