Welcome to the Hazardous Waste Information network (HWIN),
the first large-scale electronic manifest system in North America. HWIN allows hazardous waste generators, carriers, and receivers to register their activities with the Ontario Ministry of the Environment online. It also enables users to create and process electronic manifests over the web.

HWIN is an important part of the Ministry's commitment to strengthen Ontario's hazardous waste management framework. It will enhance the quality and accessibility of hazardous waste information in Ontario. HWIN also offers significant benefits to industrial users in the form of reduced costs for manifest transactions, record-keeping and reporting.
