A 25-year-old former Conservative party worker faces up to five years in jail after being found guilty of violating the Election Act.
Michael Sona was convicted this morning in connection with 6,700 automated phone messages being sent to voters instructing them to go to the wrong pollling station on federal election day in 2011.
Sona, who worked for the losing Conservative candidate in Guelph, did not testify in the case.
The person who registered the phone for the robocalls used the name Pierre Poutine.
A key witness in the case was Andrew Prescott, who was the Conservatives' deputy campaign manager in Guelph in 2011.
He spoke in court after receiving a written guarantee from the Crown saying it had no intention of charging him, according to an unnamed source quoted in a CBC report.
Sona's lawyer, Norm Boxall, tried unsuccessfully in court to demonstrate that it was Prescott and not Sona who set up the account.
