Employers using cheap foreign labor to fill work shortages in Canada are paying more fines for violating the rules of a government program that allows them to temporarily hire employees from outside the country.

Monetary penalties issued to businesses failing to comply with the rules of the Temporary Foreign Worker Program rose to C$2.1 million in the fiscal year ending March 31. That’s a 36% increase compared with a year earlier, according to data released Wednesday by Employment and Social Development Canada.
