The best answer I can give you is that the manufacturers discharge their obligations through the fees from their own operations. They will not collect those fees from consumers to then transfer them to the province, for example. It's within their own operations. There might be eco fees put forward by different jurisdictions, and it's the purview of the provinces and territories to do so.
I think what you're pointing out is what I would call the landscape of EPR programs across the country. I mentioned the one in B.C. not long ago, which covers e-waste. Not all EPR programs cover all types of material, so that could be one example and one explanation of the delta in the recycling rate, for example, in Sweden versus in Canada.
Another important factor is the timelines for when those EPR programs are being implemented through legislation. Some may not be in effect right now or weren't in effect two years ago, so the implementation and the scope of each EPR program may have implications and impacts on the stats you mentioned.
