@davidouimet I used to manually update the names of all the fans on an excel sheet every week, and then find out who are missing, to identify those who have unliked the page. However, After the fanpage crossed 500 fans, Facebook doesn’t show the entire list of fans (it only shows list of 500 random fans). So after that point I was not able to pinpoint who has unliked the fanpage, making the whole effort futile. Anyhow it’s better use of your time to identify the reasons for the ‘unlikes’, from the Page Insights and correcting it rather than finding out who has unliked your page.
