[28] The site soon attracted a number of other former Sun News Network personalities such as David Menzies, Paige MacPherson, Faith Goldy, Patrick Moore and, briefly, Michael Coren.

"[33][34] Rebel Media received support from the Environment Minister Catherine McKenna and three journalism organizations in getting the UNFCC to grant this access,[33] after Levant's October 17 appeal to Justin Trudeau.

Kai Nagata noted "Levant and Goldy were both speakers at a rally in Toronto last week organized by The Rebel to protest a motion by Liberal MP Iqra Khalid, which calls on the government to condemn Islamophobia'" in response to the shooting.

[36] In 2017, Rebel Media hired far-right activist Tommy Robinson, founder of the avowedly anti-Islamic English Defence League, as its British correspondent.

In March 2017, one of their correspondents, Gavin McInnes, made controversial comments defending Holocaust deniers, accused the Jews of being responsible for the Holodomor and the Treaty of Versailles, and said he was "becoming anti-Semitic".

"[41] During the 2017 French Presidential Election, Jack Posobiec, The Rebel Media's Washington, D.C. bureau chief, supported far-right leader Marine Le Pen and played a role in the 2017 Macron e-mail leaks.

"[43][44] On Monday August 14, Rebel founder Ezra Levant denounced the element of the "alt-right" which had participated in the rally, stating that it "now effectively means racism, anti-Semitism and tolerance of neo-Nazism.

"[14] Freelancers Barbara Kay and John Robson also quit the Rebel, and the company was denounced by Conservative MP Michael Chong,[46] Chris Alexander,[15] Peter Kent, Lisa Raitt, and former interim leader Rona Ambrose had previously disavowed the site.

[47] Brian Jean, Jason Kenney, and Doug Schweitzer of the United Conservative Party of Alberta expressed dissatisfaction with the Rebel's editorial direction over the preceding months and said they would not grant interviews to the company.

[57] After the 2017 Conservative Party leadership race, it was revealed that Scheer's campaign manager Hamish Marshall's IT firm Torch provided IT services to The Rebel Media.

[58] On 16 October 2017, The Globe and Mail asked Scheer if he knew that Hamish Marshall shared office space with the Rebel during the leadership campaign.

[61] Scheer denounced the outlet due to its coverage of the Unite the Right rally,[62] and stated that he would stop doing interviews with The Rebel Media until its "editorial directions" changed.

[66] In June 2017, the city council of Edmonton, following complaints on social media from multiple residents, pulled its online advertisements from Rebel News.

[64] In twin lawsuits (both filed during the morning of 7 October), Menzies and another journalist at Rebel News and Andrew James Lawton of True North Centre for Public Policy applied for judicial relief related "to identical decisions made by the Leaders' Debates Commission.

The commissioner found that signs made by the organization to promote Levant's book The Libranos, which featured an image of Prime Minister Justin Trudeau and other Liberals parodying The Sopranos ought to have been registered as third-party advertising because they clearly opposed a leader during a campaign.

[76][75] Levant, whose organization had accused the commission of being "capricious, unfair, unlawful and arbitrary in denying its journalists the right to fully cover the debate" said "Today we scored one for liberty.

"[75] Justice Heneghan published her ratio decidendi in case number T-1364-21 on 7 March 2022, and wrote that "In my opinion, the Applicant established irreparable harm in terms of being prevented from participation in the political process, on behalf of the electorate.

[23][78] Levant has used Rebel Media to promote climate change denial and advocate the interests of the oil sands extraction industry in Alberta.

[24] In an article for Canada's National Observer, columnist Max Fawcett described Rebel Media as a group who undermine "the scientific consensus around climate change and vaccines".

[21] In 2021, Rebel News fundraised to pay for the legal fees of Mehmet Erhan, an Adelaide resident who was arrested and charged with breaching a health order.
