Ontario Meat Plant Requirements: What Provincial Operators Need to Know

Provincially licensed Ontario meat plants operate under O. Reg. 31/05 (Meat) and supporting Ontario Meat Plant Guidelines (MPG). This guide orients managers to what those sources expect in daily operations — not what InspectionDay decides.

Who this applies to

This guide is for provincially licensed Ontario meat plants — freestanding plants, slaughter plants, and related provincial licences under the Food Safety and Quality Act framework. Federally licensed CFIA establishments follow different federal requirements and are outside InspectionDay's current Ontario release.

The official rule

O. Reg. 31/05 sets provincial meat plant licensing and operational requirements. The MPG translates many of those expectations into operational guidance — sanitation programs, pre-operational inspections, process controls, records, and inspection readiness.

What it means operationally

• Written sanitation and operational programs that reflect how the plant actually runs.
• Daily pre-operational inspections before production begins on operating days.
• Monitoring and records for refrigeration/freezing temperatures, water, inedible materials, and other plant-specific controls.
• Records made at the time activities occur and retained for the periods required by regulation or guideline.
• Readiness for ministry inspection under the Meat Inspection Program and audit follow-up under the Meat Plant Audit Program.

What should be recorded

Ontario expects written records for pre-operational inspections, sanitation monitoring, temperature checks during pre-op, water-related monitoring where applicable, inedible material handling, and other activities tied to the plant's programs. Exact record fields depend on the requirement and the plant's written program — not on a generic checklist vendor template.

When something goes wrong

When a check identifies a problem before or during production, the plant should document what was observed, any immediate correction, and follow-up where the sanitation program or corrective-action process requires it. Ontario guidance distinguishes monitoring records from corrective follow-up; not every deviation automatically requires the same type of response.

What an inspector may review

Inspectors and auditors may ask for daily pre-op records, sanitation monitoring, temperature logs, water records, inedible material records, corrective-action documentation, and evidence that records were made on the day of the activity and retained appropriately.
