The Ontario Ministry of Labour says Johnson Controls Automotive Canada LP has been fined $155,000 after a worker was fatally injured.

The worker was killed while performing maintenance on a metal mould on Jan. 29, 2013 when a hook holding open a metal lid broke.

The J-shaped metal hook broke in half, and the worker was struck on the head, crushed between the lid and the lower section of the mould.

An investigation by the Ministry of Labour found no blocking devices had been used to prevent the elevated lid from closing while the worker was beneath it, a violation of Ontario's Occupational Health and Safety Act.

The company had pleaded guilty to failing to ensure that machinery, equipment or material that is temporarily elevated and under which a worker may pass or work was securely and solidly blocked to prevent it from falling or moving.

The fine was handed down in a Woodstock court, and company must also pay a 25 per cent victim fine surcharge.
