In Hutton v. Sayat (Fed CA, 2023) the Federal Court of Appeal cites grounds for ordering a stay of proceedings:
 Subsection 50(1) of the Federal Courts Act, R.S.C. 1985, c. F-7, grants this Court and the Federal Court the authority to stay a proceeding when a claim is being proceeded with in another court, or where it is in the interest of justice that the procedure be stayed. As noted by Justice Fothergill, the interest of justice has been interpreted broadly, and is not limited to the interests of the party but rather includes a consideration of the integrity of the judicial process: Canada (Minister of Citizenship and Immigration) v. Tobiass, 1997 CanLII 322 (SCC),  3 S.C.R. 391 at paras. 88-90; Pearson v. Canada, 1999 CanLII 8631 (FC) at paras. 20-23.
