Premier Kathleen Wynne is expected to appoint a new corrections minister today and possibly make other changes to her cabinet.
The premier's itinerary mentions a swearing-in ceremony for executive council members, suggesting more than one cabinet position will change hands.
A government source says the shuffle won't involve any members who aren't already in cabinet.
Last month, David Orazietti resigned as community safety and correctional services minister and also quit as MPP for Sault Ste. Marie, citing family reasons.
Labour Minister Kevin Flynn has been handling the corrections file, but Wynne is expected to name a permanent replacement.
Wynne will also have to call a byelection for Sault Ste. Marie by the end of the spring.
