Who this guide is for

This post is for the long tail of Ontario construction — the sole proprietor electrician, the 2-person plumbing outfit, the 4-person roofing crew, the small drywall contractor, the renovation handyman who occasionally subcontracts help. The big GCs have safety coordinators and HR teams. Small contractors don’t. The compliance reality is the same; the resources available to manage it are very different.

The good news: small contractor compliance is usually much simpler and cheaper than people expect.

The sole proprietor question: do you need first aid coverage?

Regulation 1101 under the Workplace Safety and Insurance Act applies to workers. If you’re a sole proprietor working alone — no employees, no workers performing work for you — you’re generally not subject to Reg 1101’s first aid requirements. You’re the business owner, not a worker.

However:

• The moment you hire even one employee, Reg 1101 applies
• If you regularly bring in subcontractors who work under your direction, the situation gets more complex — depending on the working relationship, they may be considered workers
• If you’re working on a customer site, the customer’s workplace safety rules may apply
• If you’re a subcontractor on a GC’s project, the constructor’s site safety program will include first aid expectations
• Trade associations, IHSA-aligned safety programs, and many insurance providers expect first aid certification even for sole proprietors

The Reg 1101 thresholds for small crews

Notice the threshold at 6 workers. Most small contractors operate around this size — sometimes 4 workers on a job, sometimes 8. The practical recommendation is to train for the larger expected crew size: Standard First Aid + CPR for the owner-operator. Once trained at that level, you cover both small and large crew scenarios.

Most common small contractor scenarios

Sole proprietor electrician with no employees

Not covered by Reg 1101. Recommended: Standard First Aid + CPR anyway. Electrical work involves cardiac arrhythmia risk from contact incidents — being CPR-trained could literally save your own customer’s life if you’re called to assess an existing problem and the homeowner is already injured.

Owner + 1 helper (small reno or trades)

Reg 1101 applies. Emergency First Aid + CPR satisfies the requirement. Best practice: both of you trained, so coverage isn’t dependent on one person being present.

Owner + 3 employees (small home builder or trades subcontractor)

Reg 1101 applies. Still in the 1–5 worker bracket, so Emergency First Aid + CPR is the minimum. Most operators train 2 of the 4 so coverage is redundant.

Owner + 5–8 employees (growing trades business)

You’ll cross the 6-worker threshold sometimes. Best practice: train the owner and at least one foreman in Standard First Aid + CPR. Either certification covers crews under 6, but you need Standard for any 6+ shifts.

Owner + 10+ employees (small GC or established trades)

Standard First Aid + CPR required. Train owner, foreman, and at least one trusted senior worker for redundancy. Consider on-site group training rather than sending people individually.

Total annual compliance cost for a small contractor

Here’s the math most people don’t run because they assume it’s expensive:

For a small contractor, the annual cost of full Reg 1101 compliance is roughly the same as a smartphone bill. The cost of being uncovered when something happens — fines, WSIB premium surcharges, civil liability, having to shut down a project — is dramatically higher.

How to actually do this without overcomplicating it

Step-by-step for a sole proprietor or small crew:

If you’re a sole proprietor

1. Take Standard First Aid + CPR Level C AED (1 time, then recertify every 3 years)
2. Keep a basic first aid kit in your van or truck
3. Done. You’re not strictly required to be certified, but you’re now positioned as a serious operator who can confidently work on customer sites and subcontract relationships.

If you’re a small contractor with employees

1. Take Standard First Aid + CPR Level C AED yourself (the owner)
2. Train at least one trusted employee in Emergency First Aid + CPR (or Standard if you ever have 6+ on a shift)
3. Buy a WSIB-compliant first aid kit and put it in your primary work vehicle or office
4. Download WSIB Form 82 (free from WSIB), fill in your designated first aider names, post it visibly in your shop or office
5. Photocopy your current first aid cards and post them beside Form 82
6. Set calendar reminders for the 3-year recertification cycle (Standard FA) or 1-year cycle (BLS if applicable)
7. You’re compliant.

If you’re a small subcontractor working on GC projects

1. Same as above, plus:
2. Confirm with the GC’s site safety coordinator what additional documentation they need from you (insurance certificates, your first aid records, etc.)
3. Confirm what site-specific safety orientation they require for your workers
4. Coordinate your first aid coverage with their broader site safety plan

Training options that fit small-budget operations

Public open class

Send yourself (and one employee) to a public Standard First Aid class at one of Life Safe’s six Ontario venues. Pay per person ($120 each), no minimum group size, schedule whenever fits your work week. Best for 1–3 people total.

Group sessions with other small operators

Some trade associations and chambers of commerce coordinate group training for member small businesses. Per-person cost can drop with a larger group split. Worth checking with your local chamber or trade association.

Two consecutive evenings

Standard First Aid is roughly 14 hours, typically split over 2 days. For owner-operators who can’t afford to lose a Saturday, two evening sessions (e.g., Tuesday and Wednesday 5pm–midnight) can fit around the workday.

Wait until off-season

For seasonal trades (roofing, painting, landscaping, exterior masonry), the slow season is the natural time to certify. Most operators do this between November and February.

Common small contractor compliance traps

• “I work alone so I don’t need anything.” Sole proprietors aren’t strictly covered, but customer site requirements, insurance expectations, and good practice all favour getting certified.
• “My helper is on contract, so they’re not my employee.” The CRA and WSIB tests for employee vs contractor are nuanced. If someone works under your direction, uses your tools, and works regular hours for you, they may be a worker for Reg 1101 purposes — even if you classify them as a contractor.
• “I’ll get certified when I get the next big job.” The next big job often requires the certification to bid. Get it before you need it.
• “My helper has a card from years ago, that’s good enough.” Standard First Aid expires after 3 years. Verify the expiry date — most “I have a card” responses turn out to be expired by 2+ years.
• Online-only courses. Don’t satisfy Reg 1101. See our WSIB approval explainer.
• No first aid kit in the truck. Required under Reg 1101 — and on construction your workplace is wherever the work is.

What WSIB looks at if you’re audited

WSIB doesn’t typically audit small contractors specifically for first aid compliance unless an incident has occurred. But if an incident happens — a worker is injured, makes a claim, or there’s a Ministry of Labour inspection — the inspector will check:

• Is there a current designated first aider on every shift?
• Is there a stocked first aid kit on site?
• Are the required postings (Form 82, certificate copies, kit location) in place?
• Are training records current?
• Did the incident response follow appropriate protocols?

Small contractors who have these basics in place sail through inspections. Small contractors who don’t end up with orders, fines, premium surcharges, and a much harder time bidding future work.

The realistic take

Small contractor first aid compliance is one of those things that feels overwhelming when you’re trying to figure it out, and feels trivial once you’ve actually done it. The total cost is a few hundred dollars every three years. The total time investment is a couple of days of training. The benefit is that you can confidently work on any site, bid any job, and respond effectively if something happens to you, your worker, or your customer.
