Thank you.
Welcome to our committee, Minister Guilbeault.
I have some questions that are associated with infrastructure.
You talked earlier about keeping wildlife safe. One of the challenges with roads and highways is the erosion of tires, which release tiny particles of a preservative called 6PPD, which then acts with ozone to create a compound that's toxic to aquatic life—for example, coho salmon.
I am aware that the EPA in the United States has started to tackle this problem in order to protect ecosystem diversity and wildlife. Has Environment Canada or Parks Canada taken up the baton on this issue of rubber tire particles that affect fish?
