Ontario group: miscellaneous organic wastes and mixed wastes.

Pharmaceutical waste from drug makers & expired stock, in the miscellaneous organic & mixed group.

Is Ontario 261 hazardous waste?

Not from the code alone. Ontario 261 names the waste stream. Whether the waste is subject waste depends on its hazardous characterization or liquid-industrial status, and on the exclusions. The waste number also needs a primary characterization letter after the 3-digit class.

For subject waste, the generator enters the class-and-letter waste number in the waste details of the Ontario hazardous waste manifest. Ontario’s exclusions and shipment rules apply.

What does Ontario 261 cover?

Pharmaceutical waste, such as human or veterinary drugs, excluding biological products and vaccines. It also takes solid or liquid residue from veterinary arsenical compounds. Whether it is hazardous is a separate decision under Ontario’s waste rules.

Is pharmaceutical waste Ontario 261 or another class?

CodeWhen it fits
261The stream is pharmaceutical waste.
312The material is pathological waste, including the biologicals or vaccines in that class.

When several characterizations apply, the registration flowchart picks the primary one. The 3-digit class doesn’t replace the flowchart or the exclusions.
