Site-specific safety plans that satisfy OHSA s.23 constructor obligations, covering every trade and phase from mobilization to demobilization.

Is a CSP legally required in Ontario?

Under the OHSA and O.Reg. 213/91 (Construction Projects), the constructor must ensure a safety program is in place. While the regulation does not prescribe a specific document format, a written CSP is the standard of practice to demonstrate due diligence and is required for COR certification.

Key Deliverables

How often should a CSP be updated?

The CSP should be treated as a living document. Update it whenever a new trade mobilizes, a significant hazard is introduced, or after any serious incident. At minimum, review monthly on active projects.
