Best management practices and waste management requirements

As a waste generator in the province of Ontario you are required to follow Ontario Regulation 347.  There are two parts to Reg 347 pertaining to Dentists.  Handling and Manifesting.

Handling Waste. Under Reg 347, a certified technician (TDG Trained), registered carrier (# A841508) and receiver (# A680198) must deal with the waste generated at your facility.  Once an item is deemed as waste and is placed in a waste container, a waste generator has 90 days to have that waste removed to keep in compliance with the regulation.


Manifesting Waste  Under Reg 347 “The wastes that are excluded from the subject waste definition for the professional office of a member of the Royal College of Dental Surgeons of Ontario and the professional office of a member of the College of Physicians and Surgeons of Ontario are wastes that are solely from a single doctor’s office or single dentist’s office.  Wastes that are consolidated from multiple doctors’ or dentists’ offices (e.g. professional offices in a medical or dental building) are not excluded from the subject waste definition.”

The regulation for manifesting waste and having a waste generator number for your office may be exempt for your particular practice, but never the regulation for handling.   If you would like assistance with obtaining an Ontario Waste Generator Number,  click on the PDF form below and forward a filled out copy to us.   If you are interested in a 90 day courtesy call  we are happy to do so.  At that time you could let us know if you require service.
