Frequently Asked Questions

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.

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. The Ministry can be contacted at [email protected]

See FAQ: Will I pay my fees using a prepaid account like in HWIN?

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?

Starting January 1, obligated parties are required to report on waste management activities, including manifesting, through the online HWP Registry instead of reporting through the Ministry of the Environment, Conservation and Park’s Hazardous Waste Information Network (HWIN) and instead of using paper manifests. 

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.

Reporting for 2022 waste shipments through the prior HWIN system is closed.

Users can pay outstanding fees or request refunds related to 2022 balances by logging into HWIN.ca. For questions related to outstanding fees and refunds email  [email protected]

An accounts payable (AP) user is responsible for managing the financial aspects of a company’s registry account.

An AP user’s functionality includes:

• Accessing and paying invoices – View, download, and make payments for invoices.
• Managing saved payment methods – Add, update, or remove stored payment options.
• Modifying data across all programs – Modify program-related information as required for billing.
• Receiving billing and payment notifications – Receive email alerts about invoices, payments, and account balances.
• Communicating with RPRA regarding billing or payment questions – Act as the main contact for financial inquiries.

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.

See FAQ: Will I pay my fees using a prepaid account like HWIN?

No. Fees will be invoiced monthly and will include applicable fees for manifests completed during the previous month. Fees for onsite disposal will be invoiced at the time the disposal activity report is completed. 

See FAQ: What payment methods are available in the Registry?

See FAQ: Who pays RPRA’s HWP Registry fees?  

See FAQ: What information is included on an invoice for HWP Registry fees? 

Fees will be charged to generators only, aligning with the current Hazardous Waste Program fee structure.

If full delegation is selected, the authorized delegate that registers the generator’s facility will pay the fees. 

If a generator has partially delegated to a service provider, the AGD can manage and report activities at the generators’ facilities, but the generator will be responsible for paying the fees. 

See FAQ: Will I pay my fees using a prepaid account like HWIN?  

See FAQ: Is there a fee to set up an account in the HWP Registry? 

Yes.  The general public can search for generators and view information about their registered facilities and wastes at the following website: https://hazardouswaste-registrations.rpra.ca/s/
