Frequently Asked Questions

The Ministry of the Environment, Conservation and Parks is responsible for overseeing the Hazardous Waste Program and conducting compliance and enforcement activities. The program is set out under Regulation 347: General – Waste Management under the Environmental Protection Act and Ontario Regulation 323/22: Subject Waste Program under the Resource Recovery and Circular Economy Act.

Questions related to the regulations should be directed to the ministry at HazardousWasteProgram@ontario.ca

All information required to be reported under the Hazardous Waste Program and Regulation 347: General – Waste Management will need to be submitted through the new Hazardous Waste Program Registry starting January 1, 2023.

However, the amended Regulation 347: General – Waste Management makes clear that a generator can delegate reporting activities to a service provider, so service providers can submit the required information to the Registry and pay fees on behalf of the generator.

See FAQ: Where can I find information about the Hazardous Waste Program and associated regulations

See FAQ: what is delegation?

More information about the program and the associated regulations is available through the following resources:

• The ministry’s Hazardous Waste Management webpage: https://www.ontario.ca/page/hazardous-waste-management-business-and-industry
• The revised Registration Guidance Manual for Generators of Liquid Industrial and Hazardous Waste.

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 HazardousWasteProgram@ontario.ca

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

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

See FAQ: When will I have to pay fees?

The mobile app, RPRA HazTrack, is available for download through the Apple APP Store and Google Play Store since November 15, 2022, the same day that the HWP Registry launched for account creation. Users have to first create an account in the HWP Registry before they can login to the app. Other app functionalities, such as manifesting, will not be available until January 1, 2023.

As from January 1, the app will allow generators, carriers and receivers to:

• View and sign manifest
• Create new manifests (“parts A and B”)
• Complete manifests (“part C”)
  • Including accepting or refusing wastes
  • Make corrections to the manifest

Users of the web-based application for the HWP Registry will use the same username and password to sign into the mobile application.

The mobile app will be inaccessible if the user has logged out of the mobile app and the user is offline, as you need a network connection to log into the app. If the user stays logged into the mobile app, they will be able to use the app offline. It is advised that drivers/users stay logged into the app, or log in before going out of an internet zone, to ensure they can always use offline mode.

Yes. The new Subject Waste Program Regulation under the Resource Recovery and Circular Economy Act, 2016, preserves and clarifies existing Hazardous Waste Program fee exemptions, which RPRA must follow when recovering the cost to operate the HWP Registry.  

Existing exemptions include:  

• Municipal hazardous or special waste 
• Contaminated sites 
• Emergencies (spills) 
• Tonnage-fee exempt recycling facilities 

How you report emergency spills will not change with the introduction of the HWP Registry. You will still be required to notify the Spills Action Centre of the spill, then complete the necessary reporting for that spill in the HWP Registry.  

When you call the Spills Action Centre, they will provide you an emergency generator registration (or EGR) number. With the EGR number, you will be able to register a facility as an EGR facility in the HWP Registry. If you do not have an existing registry account, you will need to create one in order to report the emergency spill in the HWP Registry. 

All spills and environmental emergencies must be reported to SAC before an EGR number can be issued, and the EGR number must be obtained from SAC before any subject waste can be removed from the site.

Each registry account has one account administrator, who is responsible for enrolling the company in programs (e.g., HWP, batteries, etc.) and adding/removing additional account users.   

There is one primary user for each program enrolment. In HWP, the primary user can add/remove users to the HWP program, add program roles (such as generator, carrier or receiver) and is the point of contact to receive email notifications (such as when a new invoice is available).   

Secondary users in the HWP can create and edit generator facilities and waste information (generator/AGD roles only); add ECA information and edit contact information (carrier/receiver roles only); create, edit and sign manifests.   

Driver users are specific to the carrier role in the HWP program. Drivers can create, edit and sign manifests but cannot add ECA information. 

Manifest-only users, like the driver user role, have a reduced level of access limited to viewing, creating, editing and signing manifests. They cannot view, edit, or manage facilities, or view information related to fees.  

Account admins can manage password resets for all active users in the account. Primary users are also able to manage password resets, but only for active users within the programs they are the primary user for. If secondary users, drivers or manifest-only users require a password reset, they can reach out to the account admin or primary user to do so.

An Environmental Compliance Approval (ECA) is a permission issued in Ontario by the Ministry of the Environment, Conservation and Parks that imposes activity-specific rules to ensure businesses operate their facility, site or system in a manner that is protective of human health and the natural environment.  Activities that may require an ECA include hazardous waste transportation, landfilling, waste transfer or processing, private or municipal wastewater treatment, and general manufacturing.

ECA numbers are used on manifests to identify carrier and receivers in Ontario and to validate that all parties are approved to manage the selected waste stream.  If you are a carrier or a receiving facility, all ECA numbers must be linked to your Hazardous Waste Program (HWP) Registry account.

If your facility is located outside of Ontario, you may have been issued a similar permit or receiver number by your local jurisdiction with respect to your involvement in the handling of hazardous waste. You must link this permit number to your RPRA registry account to complete the receiver information on a manifest.

If the permit number is not accepted in the HWP Registry, please contact the ministry at hazardouswasteprogram@ontario.ca and provide the following information in your request:

• Contact information: phone number, phone extension (if applicable), and email.
• Other jurisdiction approval number (if applicable)
• Role (carrier or receiver)
• Company name
• Mailing address: address, city, postal code/zip code, province/state, and country
• Receiving site information: address, city, postal code/zip code, province/state, and country
• Waste information:
  • List all Ontario waste classes this site will manage, including the three-digit number and waste product name. For more information, please see Appendix A of the updated Registration Guidance Manual for Generators of Liquid Industrial and Hazardous Waste.

Account admins can manage password resets for all active users in the account. Primary users are also able to manage password resets, but only for active users within the programs they are the primary user for. If secondary users require a password reset, they can reach out to the account admin or primary user to do so. 

See FAQ: How can I reset a password in the registry? 

The account admin or primary user navigates to the program homepage of which the user requiring a password reset is enrolled in. The account admin or primary user then clicks their username at the top right of the page to show the drop-down list and selects Manage Users. 

In the Active Users table, the account admin or primary user clicks Reset Password on the row for the user they want to reset the password for and clicks Confirm. 

The user’s password has now been reset. They will receive an email with a password reset link. 

Note: the password reset link will expire within 24 hours. If the link expires before the user creates a new password, the account admin or primary must click “Reset Password” again to restart the process. 

See the FAQ: Who can reset passwords in the registry?  

If you need to change an email address in your registry account, please contact the Compliance Team at registry@rpra.ca. Registry users cannot update email addresses themselves; this can only be completed by RPRA.
