Over the past three years, we've tracked how Canadians' information diets have shifted amid Meta's news ban and the rise of political influencers. Our latest brief draws on nearly 9M social media posts and a survey of 1,518 Canadians to see what's replacing journalism online. 🧵

New in @poqjournal.bsky.social, with Holly Ann Garnett & @abridgman.bsky.social: Are Canadians losing trust in their elections? Using data from the Media Ecosystem Observatory and the Canadian Election Study since 2008, we find trust has declined sharply on the right since 2019. 🧵
Our new incident response report exposes a coordinated network of 340 Facebook pages, largely operated from Vietnam, flooding feeds across Canada, the US, the UK, and Europe with AI-fabricated news, and inadvertently funded by Canadian public and private advertisers. 🧵
Unlike a traditional foreign influence operation, Facebook's news slop economy serves no political agenda — the same fabricated stories are recycled across politicians from rival parties. The motive is profit, but when engagement is the goal, inflammatory content wins.
Glad to share that my article "The politicization of attitudes towards misinformation: how ideology shapes epistemic beliefs, normative judgments, and policy support" is out in the Journal of Elections, Public Opinion and Parties. www.tandfonline.com/doi/full/10....

Dans la cadre des 80 ans d'Élections Québec, j'ai eu la chance de discuter avec @ledevoir.com de l'impact de la désinformation sur les élections et la confiance des électeurs, et de ce qu'il faut surveiller en 2026. www.ledevoir.com/politique/qu...
La désinformation mine-t-elle la confiance des électeurs ?
Au Québec, la confiance démocratique demeure solide, mais certains signes de fragilité apparaissent.

100 Canadian social media users, mostly influencers, account for nearly 70 % of anti-institutional conspiracy theory content online, according to a new study from researchers at @mcgill.ca and @utoronto.ca.

Great discussion with @rorywh.bsky.social on our report on conspiratorial claims in Canada’s online ecosystem. Analyzing 14M posts across 4 platforms, we find: 1. Supply is highly concentrated 2. Conspiracy content primarily circulates on X 3. High awareness, limited belief among the public
The Media Ecosystem Observatory has found that just 100 accounts in Canada are responsible for 68% of posts promoting conspiracy theories. But they are having an outsized impact on local governments. Read my latest: www.nationalobserver.com/2026/02/25/n...

Glad to have contributed to this report on the information ecosystem during the 2025 Canadian election. It highlights key challenges and potential actions to protect our elections amid GenAI-powered disinformation, political segmentation, and reduced news visibility on social media platforms.
🚨Our 2025 Federal Election report is here and it should serve as a warning for Canada to act now to protect future elections. Canada’s 2025 federal election upheld its integrity, but exposed a digital ecosystem under mounting strain. Read on to learn about our key findings 🧵
WEEKLY UPDATE: WEEK 6 OF CANADA’S 45TH FEDERAL ELECTION🚨 We open this final weekly update with 6 key reflections from our research team on the 2025 Canadian federal election. These are preliminary impressions—our full post-election report will offer deeper insight. 🧵
Over 25% of Canadians are being exposed to more sophisticated and more politically polarizing fake content. These ads don’t just defraud individuals—they risk undermining trust in journalism and the democratic process, spreading misleading political content at a critical time ⚠️
WEEKLY UPDATE: WEEK 3 OF CANADA’S 45TH FEDERAL ELECTION🚨 As Canada approaches its federal election, we're witnessing a surge in generative AI (GenAI) content that poses serious challenges to the integrity of our information ecosystem. 🧵⬇️ #GenAI #Deepfakes #CanadaElection2025
WEEKLY UPDATE: WEEK 2 OF CANADA’S 45TH FEDERAL ELECTIONS🚨 From foreign interference narratives to AI-generated conspiracies, here’s what we’re seeing this week. 🧵⬇️ #CdnPoli #Election2025
It’s official: Canada’s 45th federal election is happening on April 28. With rising threats of foreign interference & information manipulation, protecting our democracy has never been more urgent. That’s why the Canadian Digital Media Research Network (CDMRN) is stepping in. 🧵

Another thing bothering me about the Zuckerberg statement -- the assertion that fact-checkers have “destroyed more trust than they created." FCers are obviously imperfect and have made mistakes, but most of what people hear about them is ax-grinding by conservative elites, not fair-minded critiques
