WorkSafe Sounds · August 25, 2026 · 2 min read

Important: This is an educational summary of a complex legal proceeding and does not constitute legal advice. Consult a qualified legal professional for advice specific to your situation.

A worker's hand was drawn into an unguarded conveyor belt at Terminal 1 baggage handling at Toronto Pearson International Airport, causing serious injuries. The guarding had been removed for routine maintenance and had not been reinstalled before the area was returned to operation.

What Happened

  • The conveyor belt guard had been removed to facilitate maintenance work
  • The guard was not reinstalled before workers resumed activity in the area
  • No lockout/tagout procedure had been completed to verify the machine was safe before resuming operations
  • No system was in place to track guard removals or confirm reinstallation before restart
  • The supervisor on site was aware that maintenance had occurred in the area

The Outcome

The Greater Toronto Airports Authority was convicted under the OHSA and fined $300,000 plus the victim fine surcharge for failing to ensure machine guarding was maintained in place during and after maintenance activities.

Citation: 2017 ONCJ 516 · Penalty: $300,000

What This Case Teaches Ontario Employers

Machine guarding must be restored immediately after maintenance is completed — no exceptions. Supervisors cannot permit workers to resume work near moving parts until all guards have been physically verified as reinstalled and all energy isolation steps are confirmed complete. A tracking or permit system for guard removals is an essential element of an adequate guarding program.

A Guard Removed for Cleaning, Never Reinstalled — Elgin Metal Casting Fined $100,000

A foundry worker suffered a traumatic degloving injury to his forearm when it was drawn into an unguarded nip point on a conveyor drive roller assembly during a production run. An interlocked safety guard on the assembly had been removed one week earlier to facilitate cleaning access and had not been reinstalled before production resumed. No permit system existed to track guard removals, and no worker had verified that all guards were in place before starting the equipment that shift.

A Two-Hand Control Defeated With a Tie-Wrap — Flexo Products Fined $90,000

A worker suffered a traumatic amputation when a point-of-operation hazard on a die-cutting press was activated while the worker's hand was within the danger zone. The two-hand control device — a safety device designed to require both hands to be on controls before the press could cycle — had been defeated by securing it in the activated position with a tie-wrap.

The Stored Energy the Lockout Missed — Omega Mechanical Fined $120,000

A millwright suffered severe crush injuries to his dominant hand and forearm when a hydraulic press he was servicing re-actuated while he was still positioned inside the machine. An energy isolation (lockout/tagout) procedure had been posted for the machine, but it did not account for a secondary hydraulic accumulator that retained stored pressure after the main power supply was isolated. Workers had never been informed of this residual energy hazard, and the procedure had not been reviewed since the original machine installation.
