In this article, we focus on the challenges arising from guilty pleas negotiated by corporations and recorded in Canadian criminal courts. We begin with the decision relating to the guilty plea that occurred in December 2019 between the Canadian public prosecutor (the Crown) and the Montréal-based engineering company SNC-Lavalin Construction inc., a subsidiary of the group of companies SNC-Lavalin Group inc. To this end, the text dwells on the circumstances surrounding the guilty plea entered by this subsidiary to resolve the criminal case against the engineering firm, and the negative consequences that could result from it. Issues arising from guilty pleas involving corporations more generally are also examined.
