A Vancouver company has pleaded guilty to violating provincial occupational health and safety regulations resulting in the death of worker in northern Saskatchewan two years ago.

An employee of the J.D. Drilling Company Ltd. was killed on Feb. 21, 2011, when the crawler tractor he was using went through the ice at an exploration site on Cree Lake.

J.D. Drilling has pleaded guilty to failing to ensure all work at a place of employment was sufficiently and competently supervised which resulted in the death of the worker.

The company was fined $46,000 in Regina provincial court on June 19.

Three other charges were stayed.
