Newbould J. in Stetson Oil & Gas Ltd. v. Stifel Nicolaus Canada Inc , 2013 ONSC 5213 has done many Ontario litigators a great service by making the calculation of costs less of an art and more of a science.
Rule 57.01(1) of the Rules of Civil Procedure, RRO 1990, Reg 194, (as am.) [the "RCP"] sets out the general principles and factors for the court to consider when exercising its discretion to award costs under section 131 of the Courts of Justice Act.

Pursuant to sub-rule 57.01(6) of the RCP, unless there is prior agreement on costs, each party intending to seek costs for any step in the proceeding must bring to the hearing a costs outline (Form 57B) not exceeding three pages.
