WSIB Clearance Certificate Ontario: Complete Guide (2026)
What is a WSIB Clearance Certificate?
A WSIB clearance certificate is a document issued by the Workplace Safety and Insurance Board confirming your business is registered and in good standing. If you work in construction in Ontario, you need one before starting any job.
The clearance proves two things: you are registered with WSIB (or have a valid exemption), and your premiums are paid and up to date. Without it, both you and the company that hired you are breaking the law.
Who Needs a WSIB Clearance Certificate in Ontario?
In the construction industry, clearances are mandatory. Both the principal (the business hiring you) and the contractor (you) must have valid clearances before any work begins. No exceptions.
This applies to every construction trade:
- General contracting
- Electrical
- Plumbing
- HVAC
- Roofing
- Foundation and structural work
- Demolition
The only exemption: home repairs or renovations done by the resident, occupant, or family member. If you are being paid to do the work, you need a clearance.
For non-construction industries, WSIB coverage may be voluntary. But most general contractors and property managers will not hire you without one, regardless of your trade.
Do You Need WSIB as a Sole Proprietor?
This is the most common question. The answer depends on your industry.
If you work in construction, WSIB coverage is mandatory even if you are a sole proprietor with no employees. Ontario law requires it. There is no opt-out.
If you work outside construction (landscaping, cleaning, painting), you can choose voluntary coverage. Most contractors opt in anyway because: general contractors require it before hiring you, it protects you if you get injured on a job, and it is a tax-deductible business expense.
Bottom line: if you do any construction work in Ontario, register with WSIB. Do not wait until a GC asks for your clearance.
How to Get Your Clearance Certificate
There are three ways to get a WSIB clearance certificate.
1. Online Quick Access (fastest)
Go to the WSIB clearance portal at clearances.wsib.ca. No login required. Enter your business details and get your clearance number immediately if your account is in good standing.
2. Full Online Services Portal
Register for WSIB online services at wsib.ca. This gives you additional features: create contractor lists, search by business details, and set up automatic email notifications when your clearance is renewed.
3. Email Request
Email WSIB directly. Takes 3 to 5 business days. Only use this if the online options are not working for you.
Registering for the First Time
If you have never registered with WSIB:
- Go to wsib.ca and click "Register your business"
- Have your business number (BN) from CRA ready
- WSIB assigns a rate group based on your trade
- Most new businesses that need a clearance immediately must make an initial advance payment of $250. This is not a fee. It gets applied as a credit toward your future premiums.
- Once registered and in good standing, request your clearance through any of the three methods above
The process takes about 15 minutes online if you have your documents ready.
What "Good Standing" Means
WSIB will only issue a clearance if your account meets all four conditions:
- Your registration is open and active
- Your business activities are classified in the correct rate group
- You have reported premiums for all past reporting periods
- All premiums and amounts owing are paid
If any of these are out of order, your clearance request gets denied until you fix it. The most common problem: forgetting to file your annual reconciliation form.
How Much Does It Cost?
The clearance certificate itself is free. WSIB does not charge for issuing clearances.
What costs money is the WSIB premium you pay on your insurable payroll. Your rate depends on your construction class and your claims history.
2026 WSIB Premium Rates for Construction
| Class | Description | Rate per $100 of payroll |
|---|---|---|
| G1 | Residential Building Construction | $2.18 |
| G2 | Infrastructure Construction | $1.72 |
| G3 | Foundation, Structure, Building Exterior | $3.55 |
| G4 | Building Equipment Construction | $1.54 |
| G5 | Specialty Trades (electrical, plumbing, HVAC) | $2.15 |
| G6 | Non-residential Building Construction | $1.61 |
Source: WSIB 2026 Premium Rates
The average across all Ontario industries is $1.23 per $100 of insurable payroll for 2026, down from $1.25 in 2025.
Your individual rate may be higher or lower depending on your claims experience. A clean safety record gets you a discount. Multiple claims push your rate up.
The maximum insurable earnings ceiling for 2026 is $121,700 per worker. You do not pay premiums on earnings above this amount.
Quick Math
If you are a sole proprietor electrician (G5 class) paying yourself $80,000/year:
$80,000 / 100 x $2.15 = $1,720/year in WSIB premiums
That works out to about $143/month. For most contractors, WSIB premiums are a fully deductible business expense.
WSIB vs Private Liability Insurance
Contractors often confuse WSIB coverage with general liability insurance. They are not the same thing, and you likely need both.
WSIB covers workplace injuries. If you or your employee gets hurt on a job site, WSIB pays for medical treatment, lost wages, and rehabilitation. It is workers' compensation.
General liability insurance covers property damage and third-party injuries. If you accidentally flood a client's basement or a homeowner trips over your equipment, liability insurance covers the claim. WSIB does not.
One does not replace the other. A general contractor will typically ask for both your WSIB clearance certificate and your certificate of insurance (COI) before hiring you. If you only have one, you are not fully covered.
Validity and Renewal
Clearance certificates are valid for up to 90 days from the date of issue.
2026 Renewal Schedule
WSIB renews clearances on a fixed quarterly schedule:
- February 20, 2026
- May 20, 2026
- August 20, 2026
- November 20, 2026
You do not need to manually renew each time. If your account is in good standing on the renewal date, WSIB auto-renews your clearance. Set up email notifications in your online account to get a copy automatically.
Set a calendar reminder 2 weeks before each renewal date. If your premiums are behind, that gives you time to pay before the renewal fails.
How Long Does the Whole Process Take?
If you are starting from scratch, here is a realistic timeline:
- Day 1: Register with WSIB online (15 minutes). You need your CRA business number.
- Day 1: Pay the $250 initial advance if required.
- Day 1-3: WSIB processes your registration and assigns your rate group.
- Day 3-5: Your account shows as in good standing.
- Day 5: Request your clearance certificate online (takes 5 minutes).
If your account is already active and in good standing, you can get a clearance in under 10 minutes. The bottleneck is always registration and that first advance payment. Do not leave this to the last minute before a big job.
Common Mistakes
1. Letting it lapse
Your clearance expires after 90 days. If your account falls out of good standing, it will not renew. Some contractors discover this only when a GC asks for proof and they cannot provide it. By then you have lost the job.
2. Wrong principal name
Each clearance is tied to a specific principal (the company hiring you). If you enter the wrong legal name, the clearance is invalid for that contract. Always confirm the exact legal business name with your client before requesting.
3. Not covering helpers
If you hire someone for even one day, they need WSIB coverage. This includes family members. WSIB audits are common in construction. If they find unreported workers, you owe back premiums plus penalties.
4. Skipping annual reconciliation
WSIB requires you to file a reconciliation form each year reporting your actual insurable earnings. If you skip this, your account falls out of good standing and your clearance stops renewing. It is the single most common reason contractors lose their clearance without realizing it.
5. Not keeping records
You are legally required to keep copies of all clearance certificates for at least three years. Keep a dedicated folder, digital or paper. WSIB auditors will ask for these.
Penalties for Working Without a Clearance
The consequences are serious on both sides.
For the contractor:
- Maximum fine of $100,000 per offence
- Corporate prosecution: fines up to $500,000
- Individual penalties: up to $25,000 and six months imprisonment for serious violations (unreported injuries, false information)
For the principal who hired you:
- They become liable for your WSIB premiums, up to the value of the labour portion of your contract
- They face the same maximum fines
In practice, most general contractors will simply refuse to hire you without a valid clearance. Some withhold payment until you provide one. It is not a negotiation point.
