Perhaps I could give an example of a regulatory sandbox involving clean technology.
In July 2025, the Department of Transport launched a regulatory sandbox to test what the safety requirements would be for battery-powered and hydrogen-powered locomotives. Currently, the rules around train safety are specifically geared toward diesel-powered locomotives. This sandbox became particularly relevant as Canada's railways moved toward decarbonizing their fleets.
Before the sandbox was ever launched, Transport Canada commissioned a number of risk assessments to identify where the potential risks were and how to mitigate them. Then it established a series of strict safeguards, including things like ensuring that there would be proper crew training, oversight and inspections. The results of that sandbox would then be used to inform the evolution of the rail safety rules to support the introduction of low-emission clean technology.
