David Scruton entered the plea to one of the dozens of charges he is facing in provincial court in St. John's.
A sentencing hearing has been scheduled for January.
The 60-year-old Scruton is also accused of breach of trust.
The RCMP arrested him after alleging he defrauded the federal government of more than $200,000.
The Mounties say the offences took place between July 1999 and June 2007.
