How Much Do Group Benefits Cost for an Ontario Construction Company? (2026 Guide)

Real cost ranges for Ontario construction companies in 2026 — per employee, per hour, and per crew size — plus what drives the number and what most guides miss.

The honest answer up front

Group benefits for an Ontario construction company typically cost between $140 and $380 per employee per month in 2026. Most small and mid-size contractors land somewhere between $185 and $300 when the plan is structured properly.

That range sounds wide because it is. A 6-person framing crew with young workers and a basic dental plan will look very different from a 20-person mechanical contractor with older journeymen and full disability coverage. The number is real — it just moves depending on four things: who's on your crew, what coverage you're building in, how you structure disability, and whether you're buying through the right channel.

This article breaks down what actually drives the number, gives you worked examples for 5, 10, and 20-person crews, and explains the pieces of Ontario construction benefits that most generic cost guides skip entirely — like WSIB gaps, seasonal workforce eligibility, and the charges that don't show up on the headline premium.

What group benefits actually cover

Before we get into cost, it helps to be clear on what you're pricing. A group benefits plan for a construction company typically includes some combination of:

Extended health care — prescription drugs, vision care, paramedicals (physiotherapy, chiro, massage)
Dental — preventive (cleanings, x-rays), basic restorative (fillings), and sometimes major and orthodontics
Life insurance and AD&D — death benefit and accidental death and dismemberment coverage
Short-term disability (STD) — income replacement for illness or non-occupational injury, typically for the first 17 weeks
Long-term disability (LTD) — longer-term income replacement, usually kicking in after STD ends
Employee Assistance Program (EAP) — mental health counselling, financial support, and wellness resources

Not every plan needs all of these. A lot of construction owners start with health, dental, life, and EAP, and add disability once the business stabilizes. The right combination depends on your crew demographics and what you're trying to accomplish with the plan.

Do I need to include all of this from day one?

No. Most small contractors start with a disciplined core — health, dental, life, and EAP — and build from there. What you want to avoid is starting too thin and having the plan feel meaningless to employees, or starting too rich and creating renewal pressure you can't sustain.

What drives the cost for a construction company

The premium your carrier charges is not random. It's built from a small number of variables, and understanding them is the fastest way to stop feeling like benefits pricing is a black box.

Crew size is the biggest lever. More employees means more pooled risk, which means lower per-person cost. A 20-person company will almost always pay less per head than a 5-person one, even with the same plan design.

Average age matters more than most owners expect. An older crew drives higher drug costs, more dental utilization, and more disability risk. Even a 5-year difference in average age across a 10-person team can meaningfully move the renewal.

Plan design — what you cover and at what reimbursement level — is the most controllable driver. A plan with 90% dental reimbursement on major work costs more than one at 50%. A plan with a rich paramedical maximum costs more than one with a tight cap. These are real levers you can adjust.

Disability structure is often the single biggest cost driver people don't see coming. Long-term disability in particular can swing the premium significantly depending on the elimination period, benefit percentage, and definition of disability you choose. For physically demanding trades, this coverage matters a lot — and pricing it wrong in either direction is a common mistake.

Claims history starts mattering once you've been on a plan for 12 to 24 months. A clean claims year holds your renewal rate down. A heavy year — one LTD claim, a few large drug bills — can push renewal rates up 15 to 25 percent. This is why plan design and employee communication both affect long-term cost.

Industry and occupation class also feeds into disability pricing specifically. Construction trades are rated as higher-risk occupations, which affects what carriers will offer and at what rate. A licensed broker who works in the construction space will know which carriers price this category most competitively.

Cost by crew size — worked examples

Here are three realistic cost scenarios for Ontario construction companies in 2026. These are not hypothetical minimums — they reflect what a properly structured plan from a competitive carrier actually looks like.

5-person crew (framing or finish contractor, mixed ages, lean plan)

Lean plan (health + dental + life + EAP, no disability): $145 to $190 per employee per month
Monthly total: roughly $725 to $950
Hourly equivalent: approximately $0.90 to $1.20 per worker per hour

10-person company (mechanical or electrical trade, average age mid-30s, balanced plan)

Balanced plan (health + dental + life + STD + LTD + EAP): $205 to $275 per employee per month
Monthly total: roughly $2,050 to $2,750
Hourly equivalent: approximately $1.30 to $1.75 per worker per hour

20-person company (general contractor, mixed field and office, fuller plan)

Competitive plan (fuller health + dental + life + disability + EAP): $195 to $265 per employee per month
Monthly total: roughly $3,900 to $5,300
Hourly equivalent: approximately $1.25 to $1.70 per worker per hour

The per-hour framing is worth pausing on. Construction estimators think in dollars per hour — labour burden, equipment, materials. Benefits are part of your labour burden, and framing them that way makes the budget conversation easier. At $1.50 per hour per person, a 10-person plan costs about the same as one moderate equipment rental. That's useful context when you're deciding whether to make this happen.

For a more detailed breakdown of the 5 to 10 person range, see our article on group benefits cost for 5 to 10 person construction companies and our guide on cost for 10 to 20 person companies.

How do I use the per-hour number in my bids?

The simplest approach: take your annual plan cost, divide by total employee hours worked per year, and add that to your labour burden rate. Most Ontario contractors running a proper job costing system already have a place for this. If you're not tracking it, you're effectively absorbing the cost invisibly instead of recovering it on jobs.

WSIB is not a benefits plan — here's the gap

This is probably the most common misconception among Ontario construction owners who are new to group benefits: that WSIB coverage means employees are already protected.

WSIB covers occupational injuries and illnesses — things that happen on the job, caused by work. It does not cover:

Non-occupational illness — cancer, heart disease, mental health conditions that didn't happen on a job site
Prescription drugs for non-work-related conditions
Dental care
Vision care
Mental health counselling for personal or family issues
Income replacement if an employee is off work for a reason that isn't a WSIB-eligible claim

The average construction worker is far more likely to go off work for a non-occupational reason — a back problem that started slowly, a mental health crisis, a cancer diagnosis — than for a workplace accident specifically. WSIB handles one slice. Group benefits handle the rest.

For a full breakdown of what each covers and where the gaps are, see our dedicated article on the difference between WSIB and group benefits in Ontario.

The seasonal workforce problem — who's actually eligible

This is where a lot of Ontario construction benefits plans quietly fail. Most carriers require employees to work a minimum number of hours per week — typically 20 to 25 — to be eligible for coverage. That works fine for your full-time employees. It creates real problems for anyone else.

If you run a seasonal operation, lay workers off in the winter, or regularly bring on crew members project by project, you need to have a clear conversation with your broker about how eligibility is structured. The questions to ask:

Is there an hours bank provision? Some plans allow workers to bank eligible hours so coverage continues through slower periods.
What happens when someone is laid off and then rehired? Is there a new waiting period, or does coverage reinstate?
How does the carrier handle seasonal patterns? Some are more flexible than others.
Are your subcontractors or owner-operators eligible at all? Usually not, but there are exceptions.

Getting this wrong creates two problems: employees who think they're covered but aren't, and claims disputes at exactly the wrong moment. A good construction benefits advisor should be mapping your workforce structure before recommending a plan — not after.

What about union crew vs non-union?

Union employees covered by a collective agreement typically get their benefits through the union plan — your obligations are defined by the agreement. Non-union employees are where your group plan applies. If you run both, make sure you're not duplicating coverage on one side or leaving the other side unprotected.

Who pays — cost-sharing on a job-cost basis

Most group benefits plans in construction are cost-shared between employer and employee. The most common structure is the employer paying 80% of the premium and the employee contributing 20%. Some companies pay 100%. A few go 50/50, though that tends to create more employee resistance to the plan.

What this looks like in practice on a 10-person plan costing $2,300 per month:

Employer pays $1,840 (80%)
Employee contributes $460 across the team — roughly $46 each, usually through payroll deduction

There are also tax implications worth knowing. Employer-paid health and dental premiums are a tax-deductible business expense. Most extended health and dental benefits received by employees are tax-free. Life and disability premiums have different treatment — the rules are worth reviewing with your accountant or broker depending on how you structure the plan.

For a deeper breakdown of how much the employer share should be, see our article on how much Ontario employers should contribute toward group benefits.

The real cost beyond the premium

The headline premium number is not the complete picture. Here are the charges that regularly catch construction owners off guard when they see their first invoice or renewal statement.

Ontario Retail Sales Tax (RST) on insurance premiums — Ontario charges 8% RST on group insurance premiums (life, disability, and some other lines). This is not always broken out clearly on quotes, but it is real. On a $2,500 monthly premium, that's $200/month you may not have factored in.

Pooling charges — Carriers often add a pooling or stop-loss charge to protect against catastrophic claims. This fee is typically built into the premium but occasionally shown separately. Ask your broker to identify it.

Administration fees — Some carriers and some plan structures include a flat or percentage-based admin fee. This should be transparent on your quote.

Broker compensation — If you're buying through a broker, their compensation is typically built into the premium in the form of a percentage commission. This is industry standard and usually not a hidden cost, but understanding that it exists helps you ask the right questions about whether you're getting independent advice or just a sale.

When comparing quotes, ask for the all-in monthly cost including RST, pooling, and admin. Two plans with similar headline premiums can look quite different once these are added.

How to reduce cost without gutting coverage

There are real ways to bring cost down without building a plan your employees won't value. Here are the ones that actually work for small and mid-size construction companies.

Pool with other employers — Industry association plans and multi-employer pools give smaller groups access to large-group pricing. For an Ontario construction company with fewer than 10 employees, this can meaningfully reduce premiums. Ask your broker whether you qualify for any pooled programs specific to the trades.

Design the plan for your actual crew — A 28-year-old crew doesn't need the same dental maximums as a 45-year-old one. A company where most employees have working spouses with coverage doesn't need to pay for rich family dental. Fit the plan to reality rather than defaulting to a standard template.

Adjust the elimination period on disability — Moving the STD elimination period from day 1 to day 8 or day 15 can reduce premiums noticeably. If your company has the cash flow to cover a few sick days before the plan kicks in, this is one of the cleanest cost levers available.

Shop the renewal before you sign — Your carrier is pricing renewal based on your claims history. A broker who works with multiple carriers can benchmark your renewal against the market and move the business if a better fit exists. If you've been with the same carrier for three or more years without ever shopping it, you may be overpaying. See our article on why renewal rates go up for construction companies and how to respond.

Communicate the plan so people actually use it — Underutilized plans tend to have worse renewal rates over time. When employees don't use preventive dental or paramedicals, they show up with bigger claims later. A plan your crew understands and uses regularly actually performs better at renewal than one nobody touches until something goes wrong.

Can I reduce cost by going direct to an insurer instead of using a broker?

Sometimes, but usually not by as much as people expect — and the tradeoffs matter. A direct insurer typically offers one carrier's products at one set of rates. A broker with construction experience can compare multiple carriers, identify the ones that price construction trades most competitively, and help you design the plan properly. For a fuller comparison, see our article on broker vs direct insurer for small Ontario employers.

Is it worth it for a small construction company

The honest answer: for most Ontario construction companies with 5 or more employees, yes — but only if the plan is designed well and the owner is clear on what they're trying to accomplish.

Here's the retention math. The average cost to replace a skilled tradesperson — recruiting, onboarding, ramp-up, productivity loss — runs between $15,000 and $40,000 depending on the role. A 10-person plan at $250 per employee per month costs $30,000 per year. If the plan helps you keep even one person who would otherwise leave for a competitor offering benefits, it has likely paid for itself.

That's not a hypothetical. In a tight Ontario construction labour market, benefits have moved from a "nice to have" to a real recruiting factor — particularly for licensed tradespeople with options. A company without benefits is increasingly competing at a disadvantage against one with a reasonable plan.

Where it's not worth it: if you're building a plan just to check a box, with no real commitment to helping employees understand and use it. A plan that exists on paper but doesn't serve your team doesn't retain anyone.

What's the minimum crew size where benefits make sense?

Most carriers will write a group plan starting at 3 employees. At 3 to 5 people, the plan is worth exploring if you have even one key employee you can't afford to lose. At 8 or more, it almost always makes financial sense once you account for the retention value. At 15 or more, not having a plan is a competitive disadvantage in most Ontario trades markets.

Are benefits mandatory for construction workers in Ontario?

No — group benefits beyond statutory minimums (CPP, EI, WSIB) are not legally required for most non-union Ontario construction employers. But "not mandatory" and "not worth doing" are different questions. Market expectations have shifted enough that treating it as optional is becoming increasingly costly in recruiting terms.

Where to go from here

If you're pricing a plan for the first time, the best starting point is getting a real number for your specific crew — not a range from a generic guide. Crew size, average age, trades mix, and what you want to accomplish with the plan all matter.
