I think there would also be some studies done through the University of Prince Edward Island by Michael van den Heuvel. Plus, there would be statistics from the provincial government through their annual statistical review of the ongoing trends in agriculture for larger farms. The industrial model and the connection through the processors could be very well documented. I don't know whether it's all done in one study, but there would be parts that would be available through various sources.
