Glad to have contributed to this report on the 2025 election.

It highlights key challenges and potential actions to protect our elections amid GenAI-powered disinformation, political segmentation, declining trust, 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.

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 ⚠️

Ils soulignent l’importance de combiner diverses approches et de renforcer la confiance dans les institutions afin d’assurer la légitimité et l’efficacité des interventions auprès des publics cibles.

[Mathieu Lavigne @MathieuLavigne3]

Nouvelle publication dans @CJPS_RCSP @CUP_PoliSci examinant l’appui général des Québécois(es) envers les interventions des plateformes et gouvernements pour lutter contre la mésinformation.

[Mathieu Lavigne @MathieuLavigne3]

Ces résultats sont cohérents avec mes autres projets en cours, qui montrent que les personnes adhérant à la mésinformation sont aussi significativement moins susceptibles de s’exposer à la vérification des faits.
