Fact-checking journalism is the heart of PolitiFact. Our core principles are independence, transparency, fairness, thorough reporting and clear writing. We publish to give citizens the information they need to govern themselves in a democracy. It is focused on looking at specific statements made by politicians and rating them for accuracy.

Hoaxy is a tool that visualises the spread of articles online found on Twitter, or in a corpus of claims and related fact checking. The Hoaxy corpus tracks the social sharing of links to stories published by two types of websites: (1) Low-credibility sources and (2) Independent fact-checking organisations.

It is an "independent and nonpartisan fact-checker on Canadian federal politics." The team does through fact-checking of claims made by federal politicians and other public figures. Fact checks separate the facts from spin, distortion, omission, error, and lies. The organisation is run entirely by volunteers and funded by donations.
