LifeSiteNews (also known as LifeSite) is a Canadian conservative Catholic advocacy website and publication founded in 1997 by the Campaign Life Coalition, a pro-life organization. It operates as a nonprofit entity, Lifesitenews Com Inc., specializing in coverage of pro-life issues, traditional Catholic values, opposition to abortion, same-sex marriage, and critiques of progressive social policies, often framing its reporting from a conservative Christian perspective. The outlet publishes articles critiquing modern papal teachings, promoting conspiracy theories, and highlighting perceived threats to religious freedoms. It has faced significant criticism for routinely publishing misleading information and conspiracy theories, including anti-vaccine narratives and COVID-19 misinformation, leading to bans from social media platforms like Facebook, Twitter (now X), and YouTube in 2021. It has been accused of promoting far-right ideologies and has been involved in legal disputes, such as a 2023 libel lawsuit filed by a Quebec priest seeking $500,000 in damages against LifeSiteNews Canada for allegedly defamatory content. Critics, including within Catholic circles, have condemned it for sensationalism and bias. The organization maintains a global reach through its website and email newsletters, quoting figures like attorney Robert Muise in pro-life legal victories. As a nonprofit, it relies on donations and has reported revenues through IRS filings. Despite controversies, it continues to position itself as a defender of traditional values against secular and progressive influences.
