What about Mr. Mackay's suggestion to manage this at a local level as opposed to looking for a national perspective?
Your licence to operate is in large measure social. You're kind of a special creature. You have some capital costs invested by the public over the years. The Crown transferred this to you, and consideration was remitted back to the Crown. That's fine—it's kind of a moot argument. You have a special social licence going back to Confederation. Why wouldn't the sector simply call time out? You have wildfires across the country on noise, toxic spill problems, Langley, B.C. Why not make a quantum leap and take this industrial sector into the 21st century?
Why aren't you pushing for a decibel-based test? You could announce to Canadians and all those affected parties that your sector was going to meet a specified timeline. You could pull your laggards forward. Every industrial sector I've interfaced with in the last 10 years or 15 years has accepted that reality and decided to move forward.
