“In Caldwell v. Caldwell, 2023 ONSC 7715, the court reviewed the law regarding costs thrown away when a trial is adjourned, at paragraphs 8 and 11 to 13 as follows:
8 The phrase “costs thrown away” refers to a party’s costs for trial preparation which have been wasted and will have to be re-done as a result of the adjournment of the trial: Pittiglio v. Pittiglio, 2015 ONSC 3603 (CanLII) (Ont. S.C.J.) at para. 7; Middleton v. Jaggee Transport Ltd., 2014 ONSC 3041 (CanLII) (Ont. S.C.J.), at para. 5.
11 Costs thrown away are generally payable on a full recovery basis: Pittiglio, at para. 5; Milone v. Delorme, 2010 ONSC 4162 (CanLII), 2010 CarswellOnt 5535 (Ont. S.C.J.), at para. 12; Straume v. Battarbee Estate, 2001 CarswellOnt 6225 (Ont. S.C.J.), at paras. 2-3; Middleton, at para. 5. This is because the purpose of such an award of costs is to “indemnify a party for the wasted time for trial preparation arising from the adjournment”: Pittiglio, at para. 6; Legacy Leather International Inc. v. Ward [2007 CarswellOnt 527 (Ont. S.C.J. [Commercial List])], 2007 CanLII 2357, at para. 9. Such an award is not to punish the party seeking the adjournment, but to indemnify the other party for the wasted time for trial preparation arising from the adjournment: Incandescent Revolution Manufacturing Co. v. Gerling Global General Insurance Co. [1989 CarswellAlta 405 (Alta. Q.B.)], 1989 CanLII 3385, at para. 12; Pittiglio, at para. 6, citing Kalkanis v. Kalkanis, 2014 ONSC 205 (CanLII) (Ont. S.C.J.), at para. 3.
12 The court must determine what costs have actually been wasted. This is not an easy task: some witnesses will require little further preparation while some will require much: Straume, at para. 4. It has been described as an “intuitive”, rather than a scientific, process: Pittiglio, at para. 17.
13 An award of costs thrown away can be revisited at the end of the trial to determine if further costs should be awarded: Straume, at para. 37; Middleton, at para. 23; Laudon v. Roberts & Sullivan, 2007 CanLII 10906 (ON SC), at para. 20.
In Pryce v. Pryce, 2019 ONSC 3441, in a highly contested parenting case involving a request to adjourn a six- day trial scheduled to start that day, the court observed that while “much of the preparation will need to be redone in advance of the trial…” there were “tasks that will not be completely wasted, such as preparation of the opening statement, questions for witnesses and draft order.” The costs claimed were reduced from $7,585.71 to $6,102, both amounts inclusive of disbursements and HST.
The above cases relate to costs thrown away arising from the adjournment of contested trials. The principles in these cases should also apply, with any necessary modifications, to costs thrown away when a party prepares for an uncontested trial that does not proceed at the request of the other party.
In determining the appropriate quantum, the court should consider the amount that the unsuccessful party could reasonably have expected to pay in the event of lack of success in the litigation. See: Arthur v. Arthur, 2019 ONSC 938.”
