Retail Scales Certification - Mississauga Bylaws

Business and Consumer Protection Ontario 3 Minutes Read · published February 11, 2026 Flag of Ontario

In Mississauga, Ontario, businesses that sell goods by weight must use certified, legal-for-trade scales and follow federal and municipal enforcement pathways. This guide explains who certifies scales, how to confirm a device is approved for commercial use, where to get inspections, and the practical steps Mississauga retailers should take to remain compliant.

Retailers must use legal-for-trade equipment and keep verification records available on request.

Overview of Certification and Legal Authority

Certification and verification of commercial weighing devices are federally regulated by Measurement Canada under the Weights and Measures framework; manufacturers, service providers and commercial users must follow Measurement Canada rules and use devices marked as approved.[1] The City of Mississauga handles local consumer complaints and by-law matters related to business operations and may direct complainants to provincial or federal inspectors.[2]

What Counts as Legal-for-Trade Scales

  • Devices bearing a Measurement Canada verification or approval mark and used within their approved range.
  • Scales maintained and repaired by authorized service providers following manufacturer and Measurement Canada specifications.
  • Records of verification, adjustment and inspections retained by the business.

Penalties & Enforcement

Enforcement of weights and measures for retail scales is primarily by Measurement Canada; municipalities like Mississauga accept complaints and may investigate business licensing or by-law breaches and refer technical device issues to federal inspectors.[1]

Specific monetary fines and penalty schedules for non-compliant devices or false weights and measures are set out under federal legislation and enforcement policy; where the municipal page refers to compliance it does not publish federal fine amounts directly, so amounts are not specified on the cited municipal page.[2]

  • Fine amounts: not specified on the cited municipal page; consult Measurement Canada for federal penalties.[1]
  • Escalation: first and repeat offences guidance not specified on the municipal page; federal enforcement policy applies.
  • Non-monetary sanctions: orders to repair or remove devices from service, seizure, court action; exact remedies depend on federal or provincial proceedings and are not fully listed on the municipal page.
  • Enforcer: Measurement Canada is the technical enforcer; Mississauga By-law Enforcement accepts consumer complaints and may act on local licensing or by-law issues.[1][2]
  • Appeal/review: appeal routes for federal enforcement decisions are described by Measurement Canada; time limits for appeals are not specified on the cited municipal page.
Keep verification seals and service records on-site to simplify inspections or disputes.

Applications & Forms

Measurement Canada publishes requirements, forms and guidance for approvals, authorizations and verification of devices; the City of Mississauga does not publish a separate municipal form for federal device certification, so local business licences may require proof of compliance but the city does not list a dedicated scale-certification form on its public pages.[1][2]

How to Prepare Your Retail Scale for Inspection

  • Schedule regular verification with an authorized service provider as recommended by the manufacturer and Measurement Canada.
  • Keep manufacturer manuals, verification certificates and repair invoices on site for inspectors.
  • Display clear pricing and ensure weighments match advertised weights to reduce complaints.
Document verification dates to show timely compliance during inspections.

Common Violations

  • Using a device out of its approved range or with missing verification marks.
  • Failing to repair or remove a device after an order from an inspector.
  • Not keeping verification, calibration or service records on site.
