I have been going through the NRC AM Log to do updates and I compared the number of Canadian AM radio stations left on air over the years:
Year Number of Canadian AM Radio Stations
2011 329
2012 317
2013 300
2014 276
2015 261
2016 256
2017 246
2018 232
2019 216
2020 210
2021 208
2022 205
2023 191
Going going gone seems to be the pattern. 2023 is the year it went below 200 in decades.
