Carrier and Receiver-Focused Information Sessions

On August 10 and 11, 2022, we hosted two sessions on the Hazardous Waste Program Registry: one for carriers and one for receivers. These webinars were designed to help carriers and receivers understand how to use the HWP Registry ahead of the new system opening for account creation on November 15, 2022 and how to support generator clients with the delegation process as an authorized generator delegate.

We also presented a live demo of the registry, which showcased the functionality of creating a new manifest on the mobile app and how the information submitted through the app is replicated in the desktop application (i.e. live synchronization). This demo was created and led by our technology partners, PwC Canada and Vyana.

These webinars are part of a series of information sessions for future registry users focused on training and guidance. The sessions will support obligated parties to use the system ahead of the registry launch in the winter.
