PETERBOROUGH -- Dean Del Mastro, who was convicted Friday on Elections Canada charges, says the judge was wrong and he has no plans to step down as Peterborough's MP.

Justice Lisa Cameron delivered her verdict on four charges against Del Mastro and three against his former official agent, Richard McCarthy, after an hour-long summation of her findings. She found the MP guilty of three charges and stayed the fourth; McCarthy was convicted as well. Del Mastro faces a $2,000 fine and the possibility of up to a year in jail on each charge.

Outside court, Del Mastro said the judge got it wrong.

"Ultimately, I know what the truth is," Del Mastro said after Cameron found him guilty. "That's her opinion. I respect the judge, but at the same time I know the truth.

"I intend to still occupy (my seat,)" he said. "I received more votes than anyone in my riding in history."

When asked about the judge's determination that he cheated to win that seat, he said "That's not true."

Del Mastro could lose his seat - the Canada Elections Act calls for anyone convicted of an offence under the act to be barred from holding office for five years from the date of conviction.

"This is obviously not a final decision," he said, not clarifying whether he meant he'd appeal the verdict. "I guess that means we'll be looking at the judge's decision."

Del Mastro and McCarthy, the accountant in charge of his election campaign finances in 2008, were both charged with overspending, under-reporting and with having filed an incorrect return to Elections Canada. Del Mastro was found guilty on all four counts, McCarthy on three.
