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.

Only hazardous waste from facilities and waste streams that are set up in the new registry can be shipped, stored, processed, or disposed as of January 1, 2023. Generators, carriers, and receivers must have an account in the new registry to be listed on a manifest, create, edit or sign manifests, or report on-site waste activities, among other activities.
Creating an account is easy and straightforward. To make it easier, have the generator numbers, HWIN usernames and Environmental Compliance Approval (ECA) numbers for your business readily available.
The HWP Registry and the mobile app were built and tested by RPRA staff, ministry staff, industry stakeholders and external technology vendors to be efficient and user-friendly. To set up an account, follow the steps below:
- Go to registry.rpra.ca
- Click the Create New Account link if you do not already have a registry account
- Enter your business contact information
- Enroll in the Hazardous Waste Program Registry as a generator, carrier, receiver or Authorized Generator Delegate (AGD). An email will then be sent with instructions to activate your account
Check out these step-by-step instructions for account creation and retrieving HWIN data.
Carriers and receivers can link existing environmental compliance approval (ECA) numbers to their account. Check out this “how-to” video to link your ECA numbers.
If you have been authorized to act as a full delegate, you should have the generator numbers and HWIN usernames for each of your clients. If acting as a partial delegate, please reach out to new clients to ensure they have their accounts and facilities set up.

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.

No. If a facility is closed and/or will not be generating hazardous or liquid industrial waste in 2023 and beyond, you do not need to register the facilities in the HWP Registry.
Also, data from inactive facilities in HWIN will not be migrated to the HWP Registry.
See FAQ: Will HWIN users’ data be migrated to the HWP Registry?
-
Yes, all users who have an active waste stream associated with an active facility and have not delegated account creation to an Authorized Generator Delegate are required to create an account in the HWP Registry. Account creation consists of entering your company name and contact information and creating usernames and passwords. Once you create an account in the new registry, you will be able to migrate all of your existing generator numbers from HWIN (and associated facility and waste information) to your one company account.
If you are a generator who is fully delegating to an Authorized Generator Delegate (AGD), you will not have to create a Registry account. In that case, the AGD will manage your facility and waste information under their own Registry account.
If you are a generator who doesn’t have an active waste stream associated with an active facility, there is no need to create a registry account or delegate an AGD to do so on your behalf.

Yes. Carriers and receivers are required to create an account in the HWP Registry and link their active Environmental Compliance Approval numbers to their Registry accounts. Starting January 1, 2023, businesses and institutions regulated by the Hazardous Waste Program are required to report information through the Registry instead of through HWIN. Only carriers and receivers who have Registry accounts will be able to be listed on manifests.

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.

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
