Medical waste disposal in Ontario is governed by a layered framework built on Regulation 347 (General – Waste Management) under the Environmental Protection Act, supported by national standards such as CSA Z317.10. This guide covers Reg 347 waste categories, biohazard bag requirements, segregation and storage rules, and the questions compliance managers ask most often.
Ontario Reg 347 Basics
Ontario Reg 347 defines biomedical waste and sets the rules that govern it from the point of generation to final treatment. Biomedical waste under the regulation includes pathological waste (tissue and organs), human body parts, human blood and body fluids, sharps such as needles and scalpels, laboratory waste including cultures, and pharmaceutical or cytotoxic waste. Each class has its own packaging and handling expectations, and mixing classes at the source is a common source of non-compliance.
The generator stays responsible for the waste even after a hauler takes it away, so documentation matters as much as the bag. Waste management systems — transporters and treatment facilities included — must operate under an Environmental Compliance Approval (ECA) from the Ontario Ministry of the Environment, Conservation and Parks. Ask your hauler for proof of its ECA and keep manifests on file.
Biohazard Bag Requirements
Red bags are the accepted standard for biomedical waste in Ontario. The bags must be leak-resistant, puncture-resistant, and strong enough to survive handling and transport without splitting. CSA Z317.10, the Canadian standard for handling health care waste materials, sets the performance and marking expectations compliant bags are tested against.
Practical details count. Biomedical waste bags are typically 1.5 to 2.0 mil (0.038 to 0.051 mm) thick with reinforced, heat-sealed seams. Each bag should carry the biohazard symbol, the facility’s name, the waste class, and the date; CSA Z317.10 details the marking requirements.
CliniEco’s red 30-gallon biohazard bags are built for this duty, with leak-proof construction suited to exam rooms, dental chairs, and lab benches.
Segregation and Storage
Segregation begins at the point of generation. Sharps go directly into puncture-resistant containers, red bag waste stays separate from recyclables and general waste, and pharmaceutical or cytotoxic waste is kept apart unless your hauler confirms it can be combined. A colour-coded station — red for biomedical waste, clear for recyclables, black for general waste — reduces mistakes on busy days.
Storage areas must be clearly marked, secured against unauthorized access, and protected from leaks with secondary containment such as a rigid bin or spill tray. Ontario Reg 347 sets time limits: anatomical waste and animal waste must leave the generating site within seven days. For other biomedical waste classes, schedule pickups to match your volume so nothing accumulates.
Choosing the Right Waste Bags
Bag size should match your bins. A 30-gallon bag fits the standard wheeled containers in most treatment areas, while smaller formats suit specimen collection and satellite stations. Overfilling is a common cause of bag failure, so leave headroom at pickup time.
Material matters too. Low-density polyethylene (LDPE) gives biomedical waste bags the flexibility and puncture resistance daily handling demands. For facilities cutting plastic use, CliniEco also carries PLA biodegradable waste bags made from plant-based polylactic acid — a practical fit for general and compostable streams such as cafeteria waste and LTC dining areas. Specimen transport has its own needs; CliniEco’s 95 kPa specimen bags (95 kPa tested) keep samples secure in transit.

FAQ: Medical Waste Regulations in Ontario
What colour bags are used for medical waste in Ontario?
Red bags are the accepted standard for biomedical waste across the province. Reg 347 does not prescribe a colour, but haulers and treatment facilities expect a red bag with a biohazard symbol, and CSA Z317.10 sets the performance and marking requirements those bags must meet. CliniEco’s red 30-gallon biohazard bags fill this role.
Does Ontario require a licence to haul medical waste?
Yes. Under the Environmental Protection Act and Reg 347, any waste management system — including transport of biomedical waste — must hold an Environmental Compliance Approval (ECA) from the Ontario Ministry of the Environment, Conservation and Parks. Confirm your hauler’s ECA before signing and keep manifests for audits.
Can PLA bags be used for biohazard waste?
PLA (polylactic acid) bags are biodegradable and suit general and compostable streams. Reg 347 does not dictate bag material, but biomedical waste still needs leak-resistant, labelled packaging that meets CSA Z317.10, and your treatment facility must accept it. For regulated waste, pair CliniEco’s red biohazard bags with your hauler’s requirements; use PLA eco bags for non-regulated streams.
How long can clinics store biomedical waste on site?
Ontario Reg 347 sets a seven-day limit for anatomical waste and animal waste stored at the generating facility. Other classes have no blanket limit, so schedule pickups by volume and keep storage marked, secured, and leak-proof.
Compliance-ready supplies make the routine easier. CliniEco Medical supplies red biohazard bags, PLA biodegradable bags, specimen bags, nitrile gloves, and masks to clinics, laboratories, and long-term care homes across Canada, with volume pricing for bulk facility orders.
