Hours before Election Day, London's top mayoral contenders are keeping busy until the polls open.

Although some in the race are claiming questionable early poll results may have set the tone for the rest of the campaign.

"It was done basically in London west. It ignored London east and London south. You know as I said from the start those polls have been heavily favoured to one candidate and it's made it difficult for other candidates to get the right balance. But nonetheless we know from door-knocking we're in the race," says mayoral hopeful Joe Swan

That candidate is Matt Brown who was found campaigning in his own neighbourhood Sunday.

The front-runner in the race credits his success to his early campaign start.

"Back in May, I knocked on a door and a resident told me, 'Look Matt, you're applying for a job. And I want to hear about your ideas and I want to hear how you want to move London forward. I don't want to hear you criticizing the other candidates' and I took that to heart. I think that's what all Londoners want to see," says Brown.

Meanwhile, Paul Cheng, a self-described David in a David and Goliath battle tells CTV News that the polls are not telling the full story.

"There's some polls that were selectively displayed. Some that were not favourable to the Goliath were not displayed at all. So it's selective information...only when they want it released," says Cheng.

Polls close at 8 pm Monday.
