More than $6 million in corrective premium adjustments were identified in Ontario’s trucking sector in Q4 2025, as enforcement by the Workplace Safety and Insurance Board (WSIB) continues to uncover widespread non-compliance with workers’ compensation requirements.

The WSIB completed 38 audits across the trucking industry in the past three months and two of the audited companies were assessed adjustments exceeding $1.4 million each, according to the latest news release from the Ontario Trucking Association (OTA).

OTA says it estimates that the WSIB has now recovered up to $20 million in previously unpaid premiums through its enforcement activity in the past several years while strengthening workplace protections and helping level the playing field for compliant carriers.

However, the association says the persistence of violations — as proven by the audits of the last quarter of 2025 — highlights the need for additional enforcement resources and continued political support.

“The WSIB’s enforcement work in the trucking industry deserves recognition. These audits have recovered tens of millions in unpaid premiums and, more importantly, have strengthened protections for workers across Ontario,” said Jonathan Blackham, OTA director of policy and public affairs, in the release.

“The results clearly show continued non-compliance remains a serious issue. To build on this progress and ensure lasting compliance, the WSIB must be supported with additional resources and strong political backing. Protecting workers requires not just rules on paper, but the capacity to enforce them.”
