This study estimates fees paid for gold and hybrid open access articles in journals published by the oligopoly of academic publishers, which acknowledge funding from the Canadian Tri-Agency. It employs bibliometric methods using data from Web of Science, Unpaywall, open datasets of article processing charges list prices as well as historical fees retrieved via the Internet Archive Wayback Machine for journals published by Elsevier, Springer-Nature, Wiley, Sage and Taylor & Francis to estimate article processing charges for open access articles published between 2015 and 2018 that acknowledge funding from the Canadian Federal funding agencies CIHR, NSERC, and SSHRC, as well as grants jointly administered by the Tri-Agency. 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 US 27. 6 million.
