The former leader of Saskatchewan's Green Party has been found guilty of not completing her census, despite Ottawa's controversial decision to scrap the mandatory long-form survey.

Sandra Finley, 61, was charged in 2008 for non-compliance after she refused to fill out her census in protest for Statistics Canada buying software from U.S. weapons manufacturer Lockheed Martin.

"I do not wish to be complacent in the enrichment of (Lockheed Martin)," she told CTV's Power Play Friday.

Finley argues the mandatory census violated her privacy rights, an argument her lawyer lost in court.

Finley is due back in court Jan. 20 for sentencing. She could face three months in jail and a $500 fine.

She plans to appeal the decision.

Finley led the Saskatchewan Green Party from 2006 to 2008.

The Conservatives decided to scrap the mandatory long-form census last year, saying it was too intrusive. The decision sparked controversy as statisticians said the move would lead to faulty data.

StatsCan boss Munir Sheikh resigned in protest.
