After the Liberals accused the Conservatives of intentionally sending voters to a wrong polling station in London North Centre, PC candidate Nancy Branscombe quickly sent out a letter of apology.

“Today, I was made aware that letters from my campaign may have caused some confusion for residents of 64 households in the riding of London North Centre. I want to apologize for any inconvenience. We are contacting these households to clarify,” she wrote.

The letter was sent out after PC leader Tim Hudak ducked questions about the allegations at a London campaign stop at candidate Jeff Bennett’s office.

Liberal Deb Matthews, the riding incumbent, showed up there and demanded an explanation.

“It was clearly directed to Liberal party supporters telling them to vote in the wrong place. It is completely unacceptable, it is immoral, it is unethical and it is illegal,” she says.

Matthews says her office was notified by a voter who received a letter from federal Tory campaign aide, Tim Gatten.

It directed the person to vote at Ridgeview Community Church, the wrong location.

Matthews says the same letter was sent to Liberal supporters in Niagara before a byelection in February.

“The person who received this lives a 15-minute drive away from Ridgeview Community Church and you'll note that it says, ‘I hope you have a wonderful long weekend.’ Well there was a long weekend before the Niagara Falls election. There's no long weekend coming up here. This is a cut and paste job of the illegal letter that was sent out in Niagara Falls and they're doing it again right here in London.  It's outrageous.”

While Hudak met with supporters at the London West campaign office, he did not take questions and slipped out when asked to respond to the allegations.

This comes a day after closing statements wrapped up in the trial for the so-called robocalls scandal in which federal Tories are accused of misdirecting Liberal supporters in the 2011 federal election.

One of the people who received a letter is Liberal supporter Miriam Hamou. She has a sign on her front lawn supporting Deb Matthews.

Branscombe knows Hamou and says she could have ended up on the list as did some other non-Conservatives.

Branscombe says this is all just a mixup.

“One of our elderly volunteers stuffed a few letters into the wrong envelope. We're making amends to it today. We're hand delivering those to we believe 60 or less and really I think Deb Matthews is trying to make a mountain out of a molehill here. And I’m sorry for that.  I guess the end of the campaign is desperate times.”

Hamou says when she first got the letter, she was angry.

“This is not the right way to do things. It doesn't matter what political party we're running for. It doesn't matter if I'm a Liberal or he's a Conservative, we should always look for people to vote,” she says.

“Maybe they made a mistake. Maybe they thought they were trying to do something good. I don't know. But it doesn't look good. It looks like coming from a nefarious place.”

Liberals have filed a complaint with Elections Ontario.
