Overview of Amendments

The updated regulation introduces refined inspection standards, expands documentation requirements, and strengthens accountability measures for site supervisors and contractors. The goal is to mitigate delays and ensure greater transparency in the oversight of construction projects.

Key Compliance Updates

• Mandatory Site Safety Plans: Projects of a defined size now require pre-approved and documented safety plans available on-site at all times.

• Revised Inspection Frequency: Larger construction projects now fall under enhanced inspection schedules.

• Digital Reporting Standards: Firms must now retain certain safety documentation digitally, enabling faster audits by the Ministry of Labour, Immigration, Training and Skills Development.

Who Is Affected?

General contractors, project managers, and tradespeople working on large-scale commercial, institutional, or infrastructure projects must update their compliance systems to reflect the June 2025 requirements.

Enforcement & Penalties

The Ministry has also introduced streamlined enforcement actions, including faster ticketing and penalty assessments for violations of updated provisions under Reg. 213/91. These penalties are intended to increase adherence and deter unsafe practices on-site.

Conclusion

The 2025 amendments to Ontario Regulation 213/91 reinforce a culture of safety, accountability, and technological readiness across Ontario’s construction sector. Builders must proactively adapt to these changes to maintain compliance, avoid penalties, and contribute to a safer, more efficient construction environment.
