Ontario’s Workplace Safety and Insurance Board is restructuring its operations, putting 466 unionized positions into the redundancy process across several communities. Sudbury, Windsor, Thunder Bay and Guelph are among the hardest-hit cities as WSIB consolidates claim and account-management functions.
The Ontario Compensation Employees Union (OCEU), representing about 3,700 WSIB workers through CUPE Local 1750, says employees received redundancy notices on August 19. The 466 figure does not necessarily mean every affected employee has already been permanently laid off. Some workers may relocate or secure another WSIB position.
The union has also warned that another 155 positions could be affected in Waterloo in roughly a year. Those positions are not included in the immediate 466 total and remain a potential future impact.
Which Ontario cities are hardest hit?
Northern Ontario accounts for a significant share of the changes. Union figures show 136 positions affected in Sudbury, 55 in Thunder Bay, 20 in Sault Ste. Marie, 15 in North Bay and 12 in Timmins — 238 positions across those five communities.
Windsor faces another major reduction with 131 positions affected, while 36 employees are affected in Guelph. Kingston and St. Catharines are also among communities identified in the consolidation.
Some locations had already lost traditional WSIB storefronts. Guelph employees have worked remotely since the Stone Road office closed in 2021, while Windsor’s former Ouellette Avenue office permanently closed in 2024.
The announcement comes amid other significant Ontario workforce reductions. Earlier staffing changes involving more than 800 TDSB school jobs also raised questions about workloads and the effect large staffing changes can have on public-facing services.
What happens to affected WSIB workers?
A redundancy notice does not automatically mean immediate dismissal. According to the union, affected employees have a three-week window to decide whether they can relocate to another WSIB location.
Workers then have six months to try to secure another position within the organization before potentially facing layoff. Seniority may also influence the process, with more senior employees potentially able to secure positions elsewhere under collective-agreement provisions.
WSIB says affected employees will receive resume-writing and job-search assistance, along with continued benefits including mental-health support during the transition.
The restructuring follows WSIB workers’ first-ever strike, which lasted six weeks. Their collective agreement runs until April 2028, and workload concerns were already part of the previous bargaining discussions.
Will WSIB claims and services continue?
WSIB says services will continue despite the staffing changes. Local teams are expected to provide in-person return-to-work assistance, while injured workers can already report injuries, submit documents, check claims and payments, and communicate about cases online.
People with existing claims should not assume their benefits or claims are ending because jobs are being relocated or offices consolidated. Current information and service options remain available through the official WSIB website.
The union argues that reducing regional staffing could increase workloads for remaining employees and make locally informed assistance harder to access, particularly in northern Ontario.

Why is WSIB restructuring now?
WSIB describes the changes as a business decision to modernize service delivery and consolidate claim and account-management functions.
The timing has attracted attention because Ontario announced a review of WSIB and seven other provincial agencies earlier in August, including Metrolinx, Legal Aid Ontario and the LCBO. The government says the reviews are focused on efficiency, productivity, governance and long-term sustainability.
However, the timing does not establish that the government review ordered the 466 redundancies. WSIB has characterized the consolidation as its own operational decision.
The cuts also arrive against a changing Canadian employment picture. Recent Canadian unemployment and jobs data provides broader context for employees who may have to enter local job markets following restructuring.
Sudbury presents another notable contrast: WSIB is investing $125 million in a new Ontario Mine Rescue Training Academy while 136 union positions in the community are affected.
What workers and claimants should watch
The final number of layoffs will depend partly on how many affected employees relocate or find other WSIB positions. The immediate figure remains 466 positions, while the additional 155 Waterloo jobs identified by the union represent a possible later impact.
For injured workers, the longer-term test will be whether WSIB can maintain timely claims processing, accessible assistance and effective return-to-work support while concentrating more functions in fewer locations. The union has said it plans to campaign to protect affected jobs and services.
