Ontario's Ministry of Labour, Training and Skills Development (MLTSD) has issued four orders in response to the incident where a worker was critically injured from a falling steel beam at Glencore's Fraser Mine in Sudbury, June 27.
The ministry said the orders were issued after inspectors attended the scene to begin a formal probe into what happened.
Neither the severity of the worker's injury nor how they are recovering has been made public.
Ministry orders are normally issued after a workplace incident where an injury has occurred to change or correct workplace practices and procedures, to change or correct the workplace environment or to change or modify pieces of equipment; all to comply with labour ministry guidance.
"MLTSD inspectors attended the scene and four orders were issued. MLTSD's investigation is ongoing," said a written email response from the ministry to Sudbury.com.
The MLTSD said it could not expand on the nature of the orders.
"As the investigation is ongoing, details on the orders are not available at this time," said the email from the ministry.
