Nipissing MPP Vic Fedeli is replacing Patrick Brown as the leader of the Ontario Progressive Conservatives.
Brown resigned yesterday after allegations of sexual misconduct.
It's not immediately clear if the new interim leader will stay on to fight the spring election as the head of the party.
Fedeli, 61, announced he was running for the leader's position at a news conference in North Bay.
The decision to name Fedeli, the party's finance critic, came after a four-hour caucus meeting this morning.
The veteran MPP is also a two term former mayor of North Bay.
Anishinabek Nation Grand Council Chief Patrick Madahbee congratulated Fedeli.
“As former mayor of North Bay, Fedeli had a good, open relationship with First Nations,” says Grand Chief Madahbee.
The Anishinabek Nation is a political advocate for 40 member communities across Ontario, representing approximately 65,000 people.
