Program: Hazardous Waste

Topic: General , Registry , RPRA Program and Registry Fees
Fees are tied to the activities that generators report on or that are reported on their behalf by authorized generator delegates (AGDs) (e.g., manifests and on-site storage, processing and disposal). Fees will be invoiced on the first day of each month and will include all manifests completed in the previous month.

RPRA consulted industry stakeholders on the 2025 HWP Registry Fees from September 27 to November 12, 2024 and, based on the feedback received, the HWP Registry Fees have been set on the following basis:

fees is charged to generators only, aligning with the current Hazardous Waste Program fee structure

the manifest fee has been set at $6, the same rate as today, and will be charged per manifest

the tonnage fee has been set at $27.50, instead of the past $30 fee, and will only apply to shipped hazardous waste and hazardous waste that is disposed on site which remains the same as today’s framework

there is no annual registration fee

all existing fee exemptions are maintained, as per Ontario Regulation 323/22: Subject Waste Program

Topic: AGD , Generator , Registry

In the HWP Registry, one company account will be set up to manage all of that company’s facilities. The company account will have one account administrator and as many additional users as you choose. Each user will have their own username and password.

Once you create an account for your company, any user associated with the account can setup and manage all facilities under that one account. More information on account types and how to setup an account, will be made available by RPRA closer to November.

Note: As a generator, if you fully delegate to a service provider (also referred to as an authorized generator delegate or AGD), you will not have to use the HWP Registry. The AGD will set up the facilities that you have fully delegated to them under their AGD account.

If you partially delegate to a service provider, you will need to set up your registry account yourself, including initial set up of your facilities and associated waste stream information migrated from HWIN. Once you have set up a facility and identified a service provider as a partial AGD through the registry system, the service provider can register and edit your waste stream information on your behalf.

Topic: AGD , Registry

If you are interested in learning more about becoming an AGD, please reach out to RPRA at registry@rpra.ca.

In terms of setting up your registry account, when creating your account in the HWP Registry, on the “Role Selection” page, users will be able to select the role (or roles) that apply to them, including acting as an authorized generator delegate (AGD).

Prior to creating an account, selecting the AGD role and submitting information to the registry on your clients’ behalf, you will need to have an agreement in place with your client(s). You should communicate with your generator clients about their ability to delegate to a service provider and prepare your staff to answer questions about delegation.

Requirements for written authorizations to delegate, are set out in the ministry’s revised “Registration Guidance Manual for Generators of Liquid Industrial and Hazardous Waste”

Topic: AGD , Generator , Registry

Full delegation: when generators hire service providers to do all the facility and waste stream management, reporting and fee payment in the registry on their behalf, and they never have to set up accounts or use the registry.

Partial delegation: when generators want to set up their own account in the registry and pay their own fees, they can still delegate facility and waste stream management and other reporting activities to a service provider.

Please note delegation is not needed for a service provider to create manifests for your facility. Delegation is needed only for a service provider to help manage a generator’s facility and waste stream information (e.g., register or edit waste streams) or sign off on manifests on the generator’s behalf.

Topic: General , Registry
Yes, in October 2022, RPRA has migrated the facility and waste stream data identified below to the new registry to minimize the volume of data users would otherwise have to enter from scratch.

Data that has been migrated into the Registry from HWIN includes:

Active generators accounts:

Generator ID

Company details

Site location

Company official / alternate HWIN Administrator details

Site Details

Waste Identification (for active wastes):

Waste Class

Waste Stream

Land Disposal Restrictions (LDR) Notification Form

Fee exemptions

Carrier and Receiver Environmental Compliance Approval (ECA) information:

ECA number

Company Name

Site location

Company admin / official information

Waste codes

*The following data has not been migrated:

Generator accounts where the generator number or ID begins with ONR or ONF

Inactive waste streams and facilities

Manifests

On-site processing, storage and disposal information

LDR questionnaires (only LDR notification forms will be migrated)

Financial information (including account balances, payment information)

Document attachments (such as copies of Environmental Compliance Approvals)

Note: while some recently expired generator accounts might have been migrated to the registry, users should have ensured that their data in the HWIN system is accurate and up to date ahead of the migration in October to ensure their data is accessible in the registry. This may have included reactivating inactive waste streams and facilities in HWIN in order for them to be migrated to the registry.

Topic: General , Registry

As of January 1, 2023, generators, carriers, and receivers of industrial hazardous or liquid waste are required to report their hazardous waste management activities and pay fees through RPRA’s digital Hazardous Waste Program (HWP) Registry or HazTrack mobile app and instead of through HWIN (the Hazardous Waste Information Network).

The HWP Registry is open since November 15, 2022, to allow generators or their delegated service providers (also referred to as an “authorized generator delegate”) to create an account and add facilities and waste streams.

HWIN pre-paid balances have not been transferred to the HWP Registry. The regulated community no longer has access to HWIN to manage their accounts and pay fees associated with activities from 2022 or earlier.

If necessary, the ministry will contact generators to address balances remaining in HWIN pre-paid accounts from 2022.
