WSIB Form 7 — the report you file when a worker gets hurt
Form 7 is the Employer’s Report of Injury or Disease — the report Ontario employers give WSIB after a work-related injury or illness. The deadline is short and the questions are specific; this worksheet gathers everything before you file.
Free to fill and print
The worksheet opens in Blue Crane's Form Maker: fill the fields on screen, print, done — no account.

Worksheet and record, not a filing. Where an official form or filing exists, this prepares the information and keeps your copy — the filing itself is done with the regulator.
When Form 7 is required
Under Ontario’s Workplace Safety and Insurance Act, an employer must report a work-related injury or illness to WSIB once it learns the worker needed health care or lost time or wages beyond the day of the incident. The window to file is tight — the Act sets it, and late reporting can mean penalties.
The report itself is filed with WSIB, online or by the channels WSIB provides. The worksheet on this page is preparation and record-keeping — it gathers the same details so the filing takes minutes, and keeps your copy with the incident file.
What Form 7 asks for
Have these ready before you start the filing:
- Your business details and WSIB account number
- The worker’s name, job, and employment details
- When and where the injury happened, and when it was reported to you
- A factual description of what happened — what, not who was at fault
- The part of body and nature of the injury, and any health care provided
- Whether lost time is expected, and the worker’s earnings information
Pair it with the incident paper trail
A Form 7 rarely travels alone. The incident report, witness statements, and first aid record from the same event should sit in the same file — WSIB, your insurer, and the Ministry may all ask for them.
Frequently asked questions
What is WSIB Form 7?
Form 7 is the Employer’s Report of Injury or Disease — the report an Ontario employer files with WSIB when a worker suffers a work-related injury or illness that requires health care or causes lost time or wages. The obligation comes from the Workplace Safety and Insurance Act.
How quickly does Form 7 have to be filed?
The Act sets a short, firm reporting deadline that runs from when the employer learns of the injury. Check WSIB’s current guidance for the exact window — and treat it as days, not weeks. Late reporting can carry penalties.
Does a first-aid-only injury need a Form 7?
Where the worker only received first aid and there was no health care from a professional and no lost time or wages, a Form 7 is generally not triggered — but you should still record the incident and the first aid given. If health care or lost time follows later, the reporting obligation can be triggered then.
Is this worksheet the official Form 7?
No. The official report is filed with WSIB. This worksheet gathers the same information in advance and keeps your completed copy with the incident file — preparation and record-keeping, not the filing.
