An Edmonton company was fined for hiring foreign workers without authorization, according to the Canada Border Services Agency.

Empire Drywall pleaded guilty Tuesday in Edmonton Provincial Court to four counts of employing temporary foreign workers lacking proper authorization.

They were fined $9,000 for each count, totaling $36,000.

The Canada Border Services Agency — responsible for investigating people in violation of the Immigration and Refugee Protection Act — launched an investigation on the Empire Drywall in Sept. 2008.

This was the biggest imposed fine in the province since 2006.
