There are lots of different types of approaches to dealing with the issue of that price differential. It may very well depend on the type of material you're talking about.
Let me give you an example: 99% of the vehicles in Ontario are recycled. The problem with vehicles is there's no environmental standard around how they're recycled, so often scrapyards will crush cars without draining the hazardous liquids in those vehicles. You need an environmental standard to deal with that issue. For other materials there's a price issue, and with certain materials there's a larger price differential than with other materials.
You need to look at things, and that's why we've certainly been expanding our policy papers to deal with things: how would you put in place a disposal ban, disposal levies, or extended producer responsibility programs? Again, for every material the tool might be somewhat different. Again, we need to understand. That's why data is so important to understand before you jump in with a tool.
