WSIB Form 7 — Employer's Report of Injury (Ontario)

A WSIB Form 7 — Employer's Report of Injury (Ontario) in Canada is a legally binding written instrument.S.C. 1985, c. L-2).

Form 7 serves as the employer's official notification to the WSIB that a workplace injury has occurred. It provides the WSIB with the information needed to open a claim, assign a claims adjudicator, assess entitlement, and calculate the worker's loss-of-earnings (LOE) benefit. The form captures the employer's WSIB account number and NAICS industry classification, the injured worker's personal information and employment history, a detailed description of how and where the accident occurred, the nature of the injury and body part affected, information about medical treatment received, and the worker's regular earnings — which form the basis for calculating LOE benefits at 85% of net average earnings under WSIA s.43.

In Ontario, almost all employers are covered under Schedule 1 (mandatory insurance) or Schedule 2 (self-insured) of the WSIA. Approximately 300,000 Ontario employers are registered with WSIB, covering some 5 million workers. WSIB annually processes over 200,000 lost-time and no-lost-time claims. The WSIB is funded through employer premiums based on industry classification and experience rating — meaning an employer's claims history directly affects its premium rate under the NEER (New Experimental Experience Rating) program.

The legal framework governing the WSIB Form 7 — Employer's Report of Injury (Ontario) in Canada draws on several key statutes and regulatory bodies. Under the Canada Labour Code (R.S.C. 1985, c. L-2), the Canada Industrial Relations Board adjudicates federal workplace disputes. Provincial employment standards legislation — including Ontario's Employment Standards Act 2000 and British Columbia's Employment Standards Act (RSBC 1996) — governs minimum employment terms. The Personal Information Protection and Electronic Documents Act (PIPEDA) governs private-sector data handling. The Canada Revenue Agency (CRA) administers source deductions and Canada Pension Plan (CPP) contributions. Parties executing a WSIB Form 7 — Employer's Report of Injury (Ontario) in Canada should confirm the document reflects current law, including any amendments enacted since the original drafting date. The Canada Labour Code (R.S.C. 1985, c. L-2) sets the foundational requirements.

An Ontario employer must complete and submit WSIB Form 7 within three (3) calendar days of learning that a workplace injury or occupational disease requires medical attention beyond first aid or has caused the worker to be absent from work. This three-day reporting obligation applies whether the worker is full-time, part-time, seasonal, casual, or temporary — and regardless of whether the employer believes the injury is work-related or whether the employer disputes the worker's account of the accident.

Form 7 is required in the following circumstances: when a worker visits a physician, walk-in clinic, hospital emergency department, or physiotherapist for a workplace injury; when a worker is prescribed medication for a workplace injury; when a worker is absent from work for any part of a day following a workplace incident; when a worker returns to work on modified duties at reduced earnings after an injury; and when a worker develops an occupational disease (such as occupational asthma, repetitive strain injury, or noise-induced hearing loss) linked to workplace exposures.

Form 7 is not required for incidents that require only first aid administered on-site (e.g., a bandage or ice pack) and that do not result in any time away from work or medical consultation. However, employers are strongly advised to document all workplace incidents in an internal accident register, because a minor injury may later develop into a more serious condition requiring a WSIB claim, and early documentation protects the employer against late or exaggerated claims.

Employers who fail to file Form 7 within three calendar days may face WSIB surcharges, prosecution under WSIA s.149, and difficulty managing the claim. WSIB adjudicators draw negative inferences from late employer reports, and delays in reporting can result in the WSIB making entitlement decisions based solely on the worker's Form 6 report.

Under the Canada Labour Code (R.S.C. 1985, c. L-2), the Canada Industrial Relations Board adjudicates federal workplace disputes. Provincial employment standards legislation — including Ontario's Employment Standards Act 2000 and British Columbia's Employment Standards Act (RSBC 1996) — governs minimum employment terms. The Personal Information Protection and Electronic Documents Act (PIPEDA) governs private-sector data handling. The Canada Revenue Agency (CRA) administers source deductions and Canada Pension Plan (CPP) contributions.

A complete and accurate WSIB Form 7 must include the following elements to confirm prompt claim processing and protect the employer's interests in the WSIB claim process.

Part A — Employer Information: The employer's full legal name exactly as registered with WSIB, the WSIB firm account number (found on WSIB correspondence and premium statements), the full business address including postal code, a direct telephone number, and the name and title of the contact person who will manage the claim. Providing the NAICS industry classification code helps WSIB verify premium rates.

Part B — Injured Worker Information: The worker's full legal name, date of birth, Social Insurance Number (the last three digits are sufficient for identification purposes), home address and telephone number, job title and department, date of hire, and employment status. The hire date and employment status affect entitlement calculations for long-term disability benefits.

Part C — Accident Description: The exact date, time, and location of the accident. A clear, factual, and objective description of what the worker was doing at the time of the injury, what happened, and what caused the injury. Describe the specific workplace activity, any equipment or materials involved, and any environmental factors (wet floor, poor lighting, excessive weight). Avoid conclusions, blame language, or opinions. Identify any witnesses by name and position.

Part D — Medical Treatment: Whether the worker sought medical attention beyond first aid, the name of the healthcare provider or hospital, and the date of first medical treatment. If the employer has a designated healthcare provider under a workplace health program, note this.

Part E — Lost Time and Wages: Whether the worker lost any time from regular work (even for part of a day), the first date the worker was absent, the worker's regular gross earnings stated as a weekly or hourly amount in Canadian dollars, and the worker's regular hours per week. Accurate wage information is critical because WSIB calculates LOE benefits at 85% of net average earnings.

Part F — Employer Declaration: The name and title of the authorized person completing the report, their signature, and the date the report was prepared. The declaration certifies the accuracy of the information under the WSIA.
