TORONTO - The Ontario Ministry of Labour says it has laid charges against the Centre for Addiction and Mental Health over worker safety violations.

The ministry said Tuesday the centre would face four counts under the Occupational Health and Safety Act.

The charges relate to an incident in January at a CAMH facility in Toronto, where a nurse was allegedly beaten by a patient.

The ministry says the CAMH had failed to provide sufficient information, instruction and supervision to protect a worker from workplace violence or the risk thereof posed by a patient.

It also accuses the centre of failing to implement safety devices, measures and procedures to protect a worker from workplace violence or the risk thereof posed by a patient.

A first appearance is scheduled at the Ontario Court of Justice in Toronto on Feb. 5.
