OHS action plan for offices CNESST-compliant

Accounting firms, agencies, startups, admin clinics: your office with fewer than 20 employees must now have an OHS action plan. Here is exactly what to do.

Top OHS risks in an office

Musculoskeletal disorders (MSDs)

Poorly adjusted workstations, wrong screen heights, bad keyboard/mouse placement — the #1 cause of occupational injury in Quebec offices.

Psychosocial risks

Mental load, overload, conflicts, psychological harassment. Bill 59 and Bill 42 make these risks mandatorily assessed.

Air quality and lighting

Insufficient ventilation, poor lighting, screen-induced visual fatigue.

Safety — falls and electrical

Poorly managed cables, unstable filing cabinets, slippery stairs. "Minor" accidents drive up CNESST costs.

Your CNESST obligations (office < 20 employees)

  • Draft a written OHS action plan and post it
  • Identify risks via documented assessment (6 categories)
  • Designate an OHS liaison officer and train them within a year
  • Have a harassment prevention policy (Bill 42)
  • Annual plan review and 3-year CNESST report
  • Maintain a risk register with corrective measures
