Since the early 2010s, more than half of peer-reviewed journal articles have been published by the so-called oligopoly of academic publishers — Elsevier, Sage, Springer-Nature, Taylor & Francis and Wiley. These publishers are now increasingly charging fees for open access journals, especially given the rise of funder OA mandates. It is worthwhile to examine the amount of revenue generated through OA fees since many of the journals with the most expensive article processing charges are owned by the oligopoly. This study aims to estimate the amount of article processing charges for gold and hybrid open access articles in journals published by the oligopoly of academic publishers, which acknowledge funding from the Canadian Tri-Agencies between 2015 and 2018. The Tri-Agency Open Access Policy on Publications mandates that all funded research for Canadian Institute of Health Research, Natural Sciences and Engineering Research Council, and Social Sciences and Humanities Research Council grantees be made available as OA. To comply, grantees will often use grant funds to pay OA fees, or APCs. During the four-year period analyzed, a total of 6,892 gold and 4,097 hybrid articles that acknowledge Tri-Agency funding were identified, for which the total list prices amount to $USD 25.3 million ($13.1 for gold and $12.2 for hybrid).
