I think a first-off would be a publicly accessible registry of licences and quotas.
As I mentioned, there is this very large spreadsheet which DFO Pacific does make available. It has taken us a couple of years to understand it, and then to use it. I'm not a computer coder. I had to find a very specialized colleague who was able to help me with this to match identification across licences.
Something more accessible and useable than that would be very valuable as a starting point. If the minister, DFO and fisheries managers decide the market transaction piece is something they would and should be monitoring more, then that would be the vehicle you could use to do that, but the registry is the starting point.
