A construction company was fined in a Thunder Bay court Monday in connection with an accident that claimed a worker's life.

Gustavo Argueto, 24, died in June 2011 when a boom-type elevating work platform he was using toppled to the ground.

Argueto was working on the McKenzie River bridge for Teranorth Construction. The Ministry of Labour laid seven charges against Teranorth under the Occupational Health and Safety Act.

The company pleaded guilty Monday to one charge: failing to ensure a work platform is only used on a firm and level surface. TeraNorth was fined $115,000, in addition to a 25 per cent victim surcharge.
