Hazardous waste generator registration

Hazardous waste generator registration is, in Ontario, the Generator Registration Report that the operator of a waste generation facility submits through the provincial Registry for subject waste. The facility is then issued a generator registration number used when waste is transferred.

A buyer of an Ontario business that produces or stores subject waste meets this because the registration attaches to the facility, and Regulation 347 defines a generator as the operator of a waste generation facility. A change of operator therefore raises a question about whose registration applies.

What Regulation 347 requires

  • Section 18(1): file the report before the earlier of the first transfer of subject waste from the facility and 90 days after subject waste was first produced, collected or stored there.
  • Section 18(6): file a supplementary report within 15 days after a change from the information submitted.
  • Section 18(7.2): use the facility’s generator registration number in all transfers of subject waste.
  • Section 18(6.1): keep the records behind the report, at the facility or the generator’s head office, for at least three years after subject waste stops being produced, collected, handled or stored there.

What to ask, and how provinces differ

Ask for the registration number, the latest report and the carriers’ records, and ask the ministry what a new operator must file. Alberta regulates hazardous waste under its Environmental Protection and Enhancement Act and Waste Control Regulation, and other provinces have their own rules.
