Today a group of Canadian civil liberties organizations launched an interactive map of Canada which allows users to document and display instances of chilling of free expression in Canada. The Censorship Tracker is sponsored by PEN Canada, the B.C. Civil Liberties Association, the Canadian Civil Liberties Association and Canadian Journalists for Freedom of Expression.

Interactive maps offer a great way to visualize information and to situate it in a geographic context. According to a press release issued by the sponsoring organizations, the Censorship Tracker is meant to be “an accessible and reliable resource that Canadians can use to gauge restrictions on free speech in Canada.” The map allows users to view dots reflecting all posted instances of limitations on freedom of expression, or to view instances based upon the type of limitation (suppression of personal correspondence, the banning of books, limits on public protest, and so on). Data can also be filtered based on other criteria such as the source of the threat (government, corporation, media, academic institution, and so on), the method used to limit expression, and the target of the limitation. There is also a filter to allow one to see whether the report of a limitation has been verified. The website allows users to file reports on incidents that can be added to the map.

Of course, one person’s free expression is sometimes another person’s crime, and not all reported examples will be what all Canadians unequivocally consider to be unwarranted limits on free expression. Nevertheless, the goal of the map is both to assist the organizations in responding to threats to freedom of expression by allowing for broad-based, crowd-sourced data collection, and to allow Canadians to access and visualize reported instances.
