An investigation into misleading and nuisance robocalls made to voters across Canada didn't find an intention to prevent them from casting ballots, so no one will be charged, Elections Canada said today.

A 2012 media report about the investigation into robocalls in Guelph, Ont., led to hundreds of complaints about live and automated calls directing voters across Canada to the wrong polling stations. There were also complaints about annoying and harassing calls that frustrated people and may have been meant to annoy them enough not to vote.

Yves Côté, commissioner of Canada Elections, said in a news release Thursday that the investigation into those calls didn't find an intent to prevent or dissuade Canadians from voting.

"Ultimately, investigators have been able to determine that incorrect poll locations were provided to some electors, and that some nuisance calls occurred," the report into the calls said.

"However, the evidence does not establish that calls were made a) with the intention of preventing or attempting to prevent an elector from voting, or b) for the purpose of inducing an elector by some pretence or contrivance to vote or not vote, or to vote or not vote for a particular candidate."

One person has been charged with the misleading robocalls made in Guelph.
