As I've been elected for the last eight years, and not always in the environment portfolio, I have to say that honestly, I haven't followed it closely. My understanding is that previously, it definitely was not a floodgate.
The vast majority of actions by the environmental community or the public are generally against a government agency, demanding the right to be heard. They're more to do with standing, procedure, judicial review, and so forth. I think the floodgates argument initially put forward has been shown not to be true for that, but I think it's also very important to revisit those sections to make sure that they are updated also, to make sure that they are compliant with the North American Agreement on Environmental Cooperation.
