Inspections focus on devices used for trade: retail scales, pharmacy balances, bulk scales, and measuring devices that affect price or quantity. Inspectors verify accuracy, calibration records, seals, and that devices are marked with required capacities and divisions.

Inspection Process

  • Initial assessment and notice: inspectors may schedule or perform unannounced visits.
  • Verification tests: standard test weights or reference measures are used to check accuracy.
  • Documentation check: calibration certificates, recent adjustments, and device markings are reviewed.
  • Correction period: inspectors may issue orders to correct non-conformities within a set timeframe.
Keep calibration certificates on site and accessible to inspectors.

Enforcement is typically carried out by municipal by-law officers or the provincial consumer protection/weights and measures authority.
