Sio Silica: Key Takeaways
The political landscape in Manitoba is in turmoil as the Sio Silica scandal continues to unravel, leaving the Progressive Conservative opposition reeling. Veteran MLA Bob Lagassé’s resignation has added fuel to the fire, as he openly criticized the party’s handling of the controversy, particularly the decision to keep Jeff Wharton in caucus despite his ethical breaches.
The scandal has exposed deep fractures within the party, with Wharton having paid a $10,000 fine for violating the Conflict of Interest Act. This has prompted Premier Wab Kinew to push for a public inquiry, arguing that the Progressive Conservatives have yet to fully address the scandal’s implications.
The roots of this controversy trace back to the former government’s attempts to push the Sio Silica mine project forward after losing the 2023 election. The ethics commissioner found significant breaches, and the NDP is now leveraging this to highlight democratic and ethical concerns.
As the scandal unfolds, new revelations about Sio Silica’s involvement in a business delegation have raised further questions about ongoing lobbying efforts. The coming months will be crucial in determining the full impact of this controversy on Manitoba’s political scene.
A spokesperson said Manitobans deserve “transparency, accountability and a government that respects the fundamental principles of our democracy,” and said the inquiry could help reveal “why the decisions were made” after the 2023 election loss. ” Manitoba legislative debate published October 7, 2025, spells out that Cullen alone faced a recommended $12,000 fine, underscoring how unusually serious the assembly treated the episode.
On January 5, 2026, Kinew’s plan for a public inquiry was reported publicly. In March, Lagassé said part of the reason he left the Progressive Conservative caucus was that Red River North MLA Jeff Wharton was allowed to remain after Manitoba’s ethics commissioner found he violated the Conflict of Interest Act in connection with efforts to push the silica sand mine after the PCs had already lost the October 2023 election.
The next thing to watch is whether Manitoba actually strikes the promised public inquiry in 2026, including who will lead it, what mandate it gets, and whether it forces testimony or document disclosure that goes beyond Schnoor’s report. A fresh wrinkle this week is that opponents now say the licensing process is still compromised, even after the licence was denied in 2024 and the ethics findings landed in 2025.
In January, The Carillon reported Kinew would launch a public inquiry into the former PC government’s handling of the Sio Silica file. On May 7, 2026, fresh reporting raised new concerns about Sio Silica’s presence on a business delegation with provincial officials.
The biggest new turn in Manitoba’s Sio Silica scandal is that the fallout is no longer confined to ethics fines and old reports: it is now actively destabilizing the Progressive Conservative opposition, with veteran Dawson Trail MLA Bob Lagassé saying Jeff Wharton should have been removed from caucus over the mine affair, then quitting the PCs himself as the controversy keeps bleeding into 2026. business delegation that also included a senior Manitoba deputy minister, prompting renewed questions about access and lobbying.
