On September 26, 2023, Ontario's Workplace Safety and
Insurance Board ("WSIB") updated its Operational Policy
on the Employers' Initial Accident-Reporting Obligations
(Policy 15-01-02) bringing it in line with the Workplace Safety
and Insurance Act ("WSIA") and removing additional
time for the WSIB to receive the employer's report of injury
("Form 7") that was in place when employers were mailing
reports to the WSIB.
The WSIA requires employers to notify the WSIB within three days
of learning of an accident, if the worker seeks health care or
results in them not being able to earn full wages. The updated
Policy sets out that the "WSIB must receive an
employer's complete accident report within three business days
after the employer learns of the reporting
obligation." Business days are defined as Monday to
Friday, and do not include statutory holidays.
