A CBC News investigation has uncovered allegations of electoral fraud concentrated in the Tamil community in the east Toronto riding of Scarborough – Rouge River.

The allegations, which span both the federal and provincial ridings, centre largely on what appears to be a lack of oversight surrounding election-day additions to the official voters list.

Only Canadian citizens are legally allowed to vote in Canadian federal and provincial elections, and even people whose names are on the voters list must provide identification before they vote. In a federal election, a person who shows up at a polling station without ID can get a fellow constituent to vouch for them. In Ontario elections, voters without ID are asked to sign a form verifying they live in the riding.

It’s this polling-station process that lacks the most basic oversight, say candidates who spoke to CBC News. And the lack of oversight allows voters to illegally cast ballots in a practice the candidates say was common in Scarborough – Rouge River during last May’s federal election and in October’s provincial election.

Marlene Gallyot, a federal Conservative candidate who lost to the NDP’s Rathika Sitsabaiesan, has complained to Elections Canada, alleging ineligible voters “by the dozens” turned up on voting day and filed ballots illegally.

"They came with a Future Shop bill,” she told CBC News. “They came in with a Canadian Tire bill. They were coming in without proper identification."
