Vic Fedeli will take over as the Tories' new finance critic, while the party's newest MPP and former Toronto deputy mayor Doug Holyday becomes the party's accountability critic.
Hudak is expected to make the appointments official and an announcement Tuesday.
Fedeli, who served as the Tories' energy critic, will replace Peter Shurman, who was ousted amid controversy over a housing allowance.
The Toronto-area MPP claimed $20,719 last year to subsidize his apartment in the city after moving to Niagara-on-the-Lake. Opposition Leader Tim Hudak sent Shurman to the backbenches after he refused to pay back the money.
Fedeli has been in the media spotlight while leading the Tory offensive against the governing Liberals over the expensive cancellation of two gas plants.
Premier Kathleen Wynne warned that she will call an election if the Opposition keeps preventing any bills from being passed.
