Group Benefits Plans for Small Businesses in Canada

A group benefits plan is the traditional employer health benefit in Canada: a group insurance policy that covers employees and their dependents for prescription drugs, dental, vision, paramedical, and more. For small businesses, the details — minimum enrolment, insured vs ASO models, cost-sharing structure, and which insurer actually fits your team size — determine whether the plan is worth the cost or quietly wasted money. Here is what you need to know before you sign.

What a group benefits plan covers

Group benefits plans are modular. Canadian insurers offer a base of core coverages that can be layered based on budget and employee needs:

Life and accidental death insurance (AD&D): Usually included in any plan as a base layer. Pays a lump sum to beneficiaries in the event of death or qualifying accidental injury. Cheapest coverage per dollar of perceived value — high retention signal at low cost.
Prescription drug coverage: Covers a percentage of prescription medications up to annual maximums. Most basic SMB plans cover 80% of drug costs after a small deductible, with an annual maximum of $5,000–$10,000. Drug coverage is the most-used benefit by employees with dependents.
Basic dental: Covers preventive and restorative dental at 70%–80% up to an annual maximum (typically $750–$1,500). Note that provincial OHIP does not cover dental for adults, making employer dental one of the most valued coverages employees receive.
Extended dental: Adds major restorative work (crowns, bridges, dentures) and orthodontics. Significantly increases premium cost. Often reasonable to add after the first plan year once claims experience is established.
Vision care: Covers eyeglasses and contact lenses, typically to a biennial maximum of $200–$400. Low premium add-on with high perceived value.
Paramedical: Covers physiotherapy, chiropractic, massage therapy, naturopathy, psychotherapy, and other services. Annual per-practitioner maximums of $300–$750 are typical. Mental health counselling coverage here has become the most-cited employee priority in post-pandemic surveys.
Long-term disability (LTD): Provides income replacement (typically 60–67% of salary) for employees unable to work due to illness or injury beyond a waiting period (90–120 days). LTD adds meaningful premium cost but is highly valued by employees who depend on their income.

Minimum enrolment requirements

Most Canadian group plan insurers impose minimum enrolment requirements to manage adverse selection (the risk that only sick employees sign up, driving up claims). Key rules:

Minimum 70% participation: The most common requirement. If you have 10 eligible employees, at least 7 must enrol. Employees who waive coverage because they have a spouse's plan are typically excluded from the denominator, which helps reach the threshold.
Minimum 3–5 enrolled lives: Many insurers will not write a group plan for fewer than 3 or 5 enrolled employees, regardless of participation percentage. For very small businesses, Chambers of Commerce Group Insurance, Manulife FlexCare, and some provincial associations operate plans that accommodate smaller groups.
Waiting periods: Most plans allow employers to set a waiting period before new employees become eligible (commonly 3 months). Some plans allow immediate coverage on day one, which can be a recruiting differentiator.

Group plan premiums are typically split between employer and employee. The split you choose affects both your cost and the benefit's retention signal:

100% employer-paid: Maximum retention signal. Employees receive the benefit at no cost, which is a meaningful differentiator against competitors who require employee contributions. Best for businesses where benefits are a primary hiring leverage.
75% employer / 25% employee (most common): The standard structure in Canadian SMBs. Reduces employer cost while keeping employee out-of-pocket low enough that most will see the value and enrol. Employee contributions are made from pre-tax payroll deductions.
50% employer / 50% employee: Acceptable for extended coverages (dental top-up, LTD). Can feel thin as the primary split and may reduce plan perceived value. Not recommended below this threshold for core coverage.

Employee premium contributions are made from post-tax or pre-tax income depending on how the plan is set up. Employer premium contributions are a deductible business expense. Employee premium contributions for non-Quebec employees are not subject to payroll taxes (CPP, EI).

Top insurers for small Canadian businesses

These are the most commonly recommended options for Canadian small businesses with under 50 employees, based on plan flexibility, minimum enrolment requirements, and claim support quality:

Manulife FlexCare (or GroupCare): Canada's largest group insurer. FlexCare is designed for groups as small as 2 lives and offers flexible module selection. Strong digital claims experience. GroupCare is for teams of 10+.
Sun Life SunFlex: Purpose-built for small and medium Canadian businesses. Modular design allows you to add or remove coverage categories annually. Good broker support across the country.
Green Shield Canada (GSC): Not-for-profit insurer with competitive pricing for small groups. Strong prescription drug formulary management. Particularly good for practices with predictable claims (employee population without major drug plan usage).
Chambers of Commerce Group Insurance Plan: Administered by Johnston Group; designed specifically for Canadian small businesses and association members. Accepts very small groups (under 5), which makes it one of the few options for micro-employers. Available through local Chambers of Commerce membership.

Insured vs Administrative Services Only (ASO)

As a group grows past 25–30 employees, two plan models become available:

Insured model (for smaller groups): The insurer takes on claims risk in exchange for fixed monthly premiums. If claims are low, the insurer profits; if claims are high, the insurer absorbs the loss (subject to renewal rate adjustments). Predictable employer cost. Suited to groups under 25–30 people where the employer cannot absorb claims volatility.
Administrative Services Only (ASO): The employer self-insures and pays actual claims, using the insurer only for administration, adjudication, and stop-loss coverage above a threshold. If the group is healthy and claims are low, the employer keeps the difference rather than subsidizing the insurer's profit. ASO becomes cost-effective typically around 25+ enrolled lives. Requires stop-loss coverage to cap catastrophic risk.

For most small businesses (under 20 employees), the insured model is the right choice. Predictability matters more than potential savings from ASO at small group sizes.

Frequently asked questions

How many employees do I need to offer a group benefits plan in Canada?

Most insurers require a minimum of 3–5 enrolled employees and 70% participation of eligible employees. Some products (Chambers of Commerce Group Insurance, Manulife FlexCare) accommodate groups as small as 2. For businesses with fewer than 5 eligible employees, a Health Spending Account is usually more practical than a group plan.

What is the most common group benefits structure for Canadian small businesses?

A basic plan covering life insurance, prescription drugs, and basic dental at 75% employer / 25% employee cost-sharing. Many businesses then add paramedical (physiotherapy, massage, mental health) as a second priority. Extended dental and LTD are typically added after the first plan year once budget is confirmed.

Can employees waive out of a group plan in Canada?

Yes, if they have coverage through a spouse's plan. Employees who waive must complete a waiver form stating the reason. Most insurers exclude waivers from the 70% participation calculation, which helps small businesses meet the minimum. Employees who waive coverage typically lose the option to re-enrol until the next open enrolment period, except for qualifying life events (marriage, birth of a child).

How does plan renewal work and will my premiums go up?

Group plan premiums are reviewed at renewal (typically annually). Insurers analyse the group's actual claims experience and adjust the premium accordingly. A group with high drug or dental claims will see larger increases. A group with low claims may see modest increases or even flat rates. For small groups (under 15 people), a single high-cost claims year can significantly affect renewal rates.

What is the difference between a group plan and a Health Spending Account?

A group plan is insurance: the insurer covers claims up to plan maximums in exchange for monthly premiums. If claims exceed premiums, the insurer absorbs the loss in the short term (subject to renewal rate adjustments). A Health Spending Account is not insurance: the employer deposits a fixed amount per employee and employees claim eligible expenses up to that balance. HSAs are more cost-predictable and flexible; group plans provide better protection against high-cost claims that exceed an HSA balance.
