After a two-month long investigation into last fall’s municipal election, Windsor Police say they've found "no evidence of criminality."

Windsor police Const. Andrew Douillard says five investigators from the Financial Crimes Unit went through 38 complaints filed in relation to the Windsor municipal election in the fall of 2014.

And after 1,500 hours of poring over election material, no irregularities were found.

"Things did have to get put on the back burner to look into this matter, because it was a concern for the complainants and us."

Drouillard says all city employees were cooperative during the investigation.

Windsor Mayor Drew Dilkens reacted Friday, saying he’s not surprised police found no criminal wrong-doing.

"Certainly I'd rather have the police spending  their time on matters that are more important, but you know what this election matter - with respect to going to the core of democracy - I understand why they took the challenge and why they undertook the investigation."

Windsor's CAO Helga Reidel says the most difficult part for city staff has been the anonymity of their accusers.

"It's very bothersome when your accusers are not willing to stand forward and be accountable for those accusations. I find that very unfortunate and, quite frankly, very telling about the legitimacy of those complaints."

Still, she says the internal look at their election process has resulted in discussions about how to improve for 2018.

"We have talked about things that will indeed cost money four years from now. We've talked about additional hiring of staff at the polls, we've talked about even additional equipment next time around."

CTV News has tried repeatedly to confirm who the complainants are, but so far none have stepped forward, and it remains unclear how many there are.
