In Mukwa v. Farm Credit of Canada (Ont CA, 2022) the Court of Appeal considered the court's inherent jurisdiction to address abuses of it's process:
[24] This court has implicit powers, that derive from the court’s authority to control its own process, to make procedural orders to prevent an abuse of process and to ensure the just and efficient administration of justice: Lochner, at para. 27; R. v. Cunningham, 2010 SCC 10, [2010] 1 S.C.R. 331, at para. 19; and R. v. Anderson, 2014 SCC 41, [2014] 2 S.C.R. 167, at para. 58.
