THUNDER BAY - Work has begun on an expansion to the Thunder Bay Correctional Centre, which is expected to help relieve overcrowding issues at the facility and the Thunder Bay District Jail. “Projects have a tendency to get pushed back or delayed so it’s always a relief to see work start,” said Shawn Bradshaw, president of OPSEU local 708 at Thunder Bay Correctional Centre. Expansions to the Correctional Centre and Kenora Jail were announced by the provincial government last October to address issues of overcrowding and are part of the province’s $500 million plan to transform correctional services in Ontario.
