The government called for the audit in August 2012 after the province’s ombudsman detected what he called questionable accounting practices and a lack of oversight.
Dwight Bishop launched an investigation after two of the agency’s former employees contacted him in October 2011 and alleged wrongdoing.
Bishop, who stepped down in 2013, found a lack of guidelines for discretionary spending and that some invoices could not be verified.
The audit was conducted by PricewaterhouseCoopers.
