LINDSAY, Ont. — Former Conservative MP Dean Del Mastro is expected to appear in a Lindsay, Ont., court for a sentencing hearing in his election overspending case today.

Del Mastro, a former parliamentary secretary to Prime Minister Stephen Harper, was convicted last fall of violating the Canada Elections Act during the 2008 election. He has since resigned his House of Commons seat.

Del Mastro’s sentencing hearing was supposed to take place last month, but it was postponed after his lawyer made an application to have a mistrial declared in the case.

Justice Lisa Cameron, who has presided over Del Mastro’s trial, has dismissed the mistrial application after hearing submissions from all sides.

Del Mastro was found guilty of exceeding spending limits, failing to report a personal contribution of $21,000 to his own campaign and knowingly submitting a falsified document.

He faces a maximum penalty of one year in jail and a $2,000 fine on each of the three convictions.
