Postmedia Detector is an extension for the Chrome browser that can help you identify and avoid news sites that are a part of the American-owned Postmedia Network.

 The 2025 Canadian Federal Election has been called, and with it will come another wave of foreign election interference. Over the past two years, attention on this issue has grown larger than ever, and Parliament responded by ordering the creation of the Foreign Interference Commission. Thankfully the effect of direct interference of foreign powers, and the complicity of our Members of Parliament was found to be minimal. However, that was a different time, and since then the global political environment has shifted dramatically with the reelection of Donald Trump.

 Domestic politics are changing in Canada in response. While the interference of Russia, China, and India are now broadly recognized, Canadians are waking up to the reality that our closest ally and partner is not the friend we once thought them to be. We as Canadians can now see clearly that the foreign interference of the U.S. and its authoritarian regime need to be dealt with as swiftly and decisively as the interference of any other hostile foreign power.

What is this project?

 Postmedia Network Canada Corp. is majority owned by American hedge fund Chatham Asset Management.

 Postmedia Network is one of the largest media conglomerates in the country, the National Post and the Financial Post being the largest of their properties. In total they own dozens of news organizations across the country and at a local level. These sites include some of the most notable news organizations in their cities, such as the Calgary Herald, the Ottawa Citizen, and the Toronto Sun. It can be difficult to realize as you scroll social media that an article you read or a headline you see is coming from one of these sites, which is what this extension aims to help with. This extension will highlight links to any site owned by Postmedia, and will warn you if you happen to find yourself on one. Hopefully with this knowledge you can be more aware of the media ecosystem and any potential biases you may have not considered.
