My understanding is that Botler, at the time, raised concerns with ISTB, the information, science and technology branch, around the payments. They were making complaints that they had not been paid by Dalian and Coradix. It wasn't until, I think, November 2022 that they raised allegations. Those went straight to the president, and the president passed those to internal affairs, which then subsequently passed them to the RCMP.
On March 26th, 2024. See this statement in context.
