Documents and evidence obtained through pretrial discovery are subject to an implied undertaking to use them only for that litigation unless the court orders otherwise (Juman v Doucette, 2008 SCC 8). Breach can be contempt of court, and breach of a lawyer's undertaking is a serious professional matter.
If your business receives another party's documents in a lawsuit, it cannot use them for business purposes outside the case.
Using discovery documents in another dispute or a commercial negotiation without court permission can lead to contempt proceedings.
