Does a party who brings the motion as well as the witnesses upon whom the moving/applying party relies have an obligation to present and present witnesses to the motion?

This obligation applies to the party who brings the motion as well as the witnesses upon whom the moving/applying party relies: Moses v. Metro Hardware and Maintenance Inc., 2020 ONSC 6684, at para. 25.

At para. 26 of Moses v. Metro Hardware, Myers J. added that a motion without notice is different than an ordinarily contested one. The one-sided format of the motion raises the moving party’s obligation of candour and requires that party to reduce the zeal with which the case is presented. As Myers J. wrote: 26 The party who moves without notice must be fair. The regular zeal that is perfectly appropriate in face of an equally zealous adversary does not apply when a party chooses to go before a judicial officer without anyone else present to keep his or her zealousness in check.
