On that point, the CBC did a documentary, and it discovered a list of employees through whom the money was funnelled. I am going to quote:
All of the former SNC-Lavalin employees and spouses named in the list who spoke to The Fifth Estate...said they were not contacted by the Commissioner of Canada Elections to let them know their names were on the document.
These are the people through whom the illegal donations were funnelled. You say there's no evidence. How could you possibly conclude that, when none of the people who were used to funnel the illegal donations were even contacted?
