TORONTO -- A Toronto-based electrical company has been fined $150,000 for an incident just before Christmas in 2010 in which one worker was killed another injured.

Ontario's labour ministry levied the fine against Stacey Electric Co. for violations of the Occupational Health and Safety Act.

Two workers were repairing a broken beacon at a railway underpass in Toronto on a cement median between four lanes of traffic.

One worker was in the bucket of a boom truck and the other worker was standing on the median when a bus struck the boom.

The worker on the median was struck and killed by the bus and the bucket as it fell to the ground and the other worker was injured.

The ministry says there were no traffic control measures such as signs or traffic cones in place during the repair operation.
