We'd have to get back to you with the latest numbers of how many have been installed.
Over the last few years, the federal government has had numerous programs to support the deployment of charging infrastructure, both electric but also hydrogen charging. I know that with the electric vehicle infrastructure side of the green infrastructure program, this was a major feature.
Within my own RD and D, we funded a pilot project between Edmonton and Calgary, called the AZTEC project. It's running a hydrogen truck between the two cities. Most recently, in budget 2022, Transport Canada was given money to do more heavy- and medium-duty vehicle hydrogen demonstrations of that technology.
