Ontario construction businesses can claim up to $2,500 back from the Workplace Safety and Insurance Board (WSIB) for each qualifying project’s Automated External Defibrillator (AED), including taxes. AEDs purchased between July 1, 2025, and June 30, 2027, qualify, and you must submit every request by July 31, 2027.
This guide explains who’s eligible, the exact claim steps in your WSIB account, and what the program does and doesn’t cover. Ontario’s new AED requirements for construction sites make an AED mandatory on qualifying projects under Ontario Regulation (O. Reg.) 157/25. The reimbursement helps offset that cost.

Who is eligible?
You’re eligible if you can confirm all five statements on the WSIB’s reimbursement request form. The form asks you to declare each one before you submit:
- Constructor: You’re the constructor of the project site. Under Ontario’s Occupational Health and Safety Act (OHSA), the constructor has the greatest control over health and safety on site.
- WSIB account: Your business is registered with the WSIB and has an active account.
- Project length: You expect the project to run for three months or longer.
- Crew size: You expect 20 or more people, including subcontractors, to work on site regularly.
- First aid: A person trained in first aid is on site whenever work is underway.
These criteria mirror the thresholds in O. Reg. 157/25. The regulation requires an AED on projects that regularly employ 20 or more workers and are expected to last three months or more.
Each qualifying project gets its own claim. You can request reimbursement for one AED on every qualifying project you run, with a separate form for each site.

How to claim, step by step
Claiming takes six steps. Most of the work is gathering details you’ll already have from your purchase.
- Buy a qualifying AED and keep the itemized invoice. The regulation calls for a Health Canada-licensed AED. Make sure your invoice shows the seller, make, model, purchase date, and price, since the form asks for each one.
- Sign in to WSIB online services and open the Business Safety Portal. From your business home menu, select “access free health and safety resources” and follow the prompts to create your portal account.
- Download the reimbursement request form. The link to the Automated External Defibrillators for Construction Projects Reimbursement Form is on the Business Safety Portal home page.
- Complete one form per project site. Have your seven-digit WSIB account number, project address, expected duration, crew size, and AED purchase details ready. Add your Notice of Project number if your project has one.
- Upload the form before July 31, 2027. Sign in to your online services account and follow the prompts to upload it. Keep your receipt or invoice on file, because the WSIB may ask for proof of purchase.
- Watch for the WSIB’s decision. The WSIB emails you within two to four weeks to approve the request or ask for more information. Approved amounts appear as a credit on your WSIB account about three weeks later.

What the reimbursement covers, and what it doesn’t
The reimbursement covers the purchase cost of one AED per qualifying project, up to $2,500 including taxes. The program pays for AEDs you buy, so leased units don’t qualify.
The device is one part of what O. Reg. 157/25 asks of construction sites. Plan to budget separately for:
- Signs at the AED and around the site showing where it is
- Installation that protects the AED from dust and moisture
- Quarterly inspections by a competent worker, with a written record
- CPR and AED training, since a trained worker must be present whenever work is in progress
- Ongoing upkeep, such as replacement pads and batteries
Our specialists can help you price these items alongside the AED, so your full compliance budget is clear from the start.
Deadlines, and what happens if you miss them
There are two dates to keep in mind for the program.
- June 30, 2027: Last day to buy an AED that qualifies
- July 31, 2027: Last day to submit your request
That gives you one extra month after purchases close to finish your paperwork. July 31, 2027, is the WSIB’s final day for requests, so late submissions won’t be accepted. Your project’s AED requirement under O. Reg. 157/25 continues either way. Submitting soon after you buy leaves time to respond if the WSIB asks for more information.
Frequently Asked Questions
How much does the WSIB reimburse for an AED?
The WSIB pays back up to $2,500 for one AED on each qualifying construction project. That limit includes applicable taxes. If your AED costs less, you’re reimbursed for what you paid. Approved amounts arrive as a credit on your WSIB account.
Can I claim for more than one construction site?
Yes. Every qualifying project can receive reimbursement for one AED, and each needs its own request form. A constructor running four eligible sites, for example, would submit four separate forms and could recover up to $2,500 for each.
Does the reimbursement cover training, signage, or installation?
No. The program pays only for the AED itself, up to the $2,500 limit. CPR and AED training, AED signs, installation, and quarterly inspections required under the regulation remain the constructor’s cost. It helps to plan for them at the same time you buy the AED.
What proof do I need?
Keep an itemized receipt or invoice that names the seller and shows the AED’s make, model, purchase date, and price. You’ll copy these details onto the request form. The WSIB may also ask to see the receipt to verify your claim.
Is my project eligible if it’s shorter than three months?
No. To qualify, you must expect the project to run for three months or more. Projects expected to last less than three months also fall outside the AED requirement in O. Reg. 157/25, so the regulation doesn’t mandate an AED there.
