Thanks very much, Mr. Chair.
Good morning, Mr. Vaughan, and good morning to your colleagues as well.
Good morning, Mr. Arseneault.
Can I go back to the safety of drinking water for a second, Mr. Vaughan?
In your judgment or assessment, is the federal role in the development of these science-based guidelines for Canadian drinking water quality the circumscribed responsibility of the federal government, or are there other responsibilities here that accrue to the federal government on water quality?
