Riadh Ben Aissa, in 2009 the president of the construction division at SNC-Lavalin (SNC), was told that his firm's proposal to build McGill University's new super-hospital was faulty. However, someone on the McGill University Health Centre (MUHC) had illegally given him a copy of the OHL consortium architectural drawings, which were favoured by the clinicians. Charles Chebl, who at the time was working under Ben Aissa and has since replaced him as head of construction for SNC, testified in May 2014 that Ben Aissa told him to incorporate the OHL design into a hasty revision of SNC's plan.
