You're absolutely right. It's not easy, because there's no direct comparison. Even when you look at western Canadian farms, you will see that they vary from farm to farm, region to region, municipality to municipality. When you start comparing to other systems around the world, it becomes very difficult to standardize that, because no one size fits all and no one size fits all across Canada. It's hard to come up with a one-size-fits-all approach to something at the border because of all those differences.
I'm not trying to over-complicate it, but that's the practical reality of how systems are done.
I strongly believe that when it comes to sustainability, farmers know what works on their farms and what doesn't work on their farms. Every single one of them is thinking about the generations to come, because they want to leave that land in better condition than they received it, so the incentive for ongoing continuous improvement on the sustainability front is inherent in their DNA, in their business models and in the future of their families. Trying to standardize that through regulation is very difficult. It's a very big challenge.
