The plaintiffs appealed an order of a case management master requiring them to post additional security for costs in complex civil litigation.
The plaintiffs were non-residents of Ontario and did not claim impecuniosity, but argued that the strength of their claims justified denying security for costs.
The court held that the master applied the wrong legal standard by requiring the plaintiffs to show an "overwhelming likelihood of success" rather than the correct standard of a "good chance of success" when assessing the merits under Rule 56.01 of the Rules of Civil Procedure.
Because this constituted an error of law, the appeal was allowed in part and the matter was remitted to the case management master for reconsideration using the proper standard.
