Background

Prior to his election, Mantha was a staffer in the riding office of Carol Hughes, the federal Member of Parliament for Algoma—Manitoulin—Kapuskasing. He lives in Elliot Lake, Ontario with his wife Pauline and their two sons.[2]

Politics

edit

Mantha ran in the 2011 provincial election as the New Democratic candidate in the riding of Algoma—Manitoulin. He defeated Liberal incumbent Mike Brown by 4,188 votes.[3][4] He was re-elected in the 2014 provincial election defeating Liberal candidate Craig Hughson by 7,668 votes.[5] Mantha was re-elected in the 2022 Ontario general election.[6]

He served the party's critic for a number of portfolios, including Northern Development and Mines, Indigenous Relations and Reconciliation[7] and Northern Development and Tourism.[8]

Mantha introduced several pieces of legislation, including a motion that was unanimously passed to create a lyme disease strategy in Ontario.[9][10]

On April 1, 2023, Ontario NDP leader Marit Stiles removed Mantha from the caucus pending the results of an investigation into alleged misconduct involving a staffer. The decision was made after Stiles received an interim report on the allegations.[11]

On August 15, 2023, Mantha was permanently removed from the NDP caucus after a third-party investigation found that the allegations of workplace misconduct levied against him were substantiated.[12]

He stood for re-election as an independent but was defeated.
