In Elguindy v. Elguindy (Ont CA, 2020) the Court of Appeal sets out the test for leave to appeal to the Court of Appeal from an exercise of discretion, such as costs:
 It is well established that leave to appeal costs should only be granted sparingly where there are strong grounds upon which this court could find that the trial judge erred in exercising his discretion: Brad-Jay Investments Limited v. Village Developments Limited, 2006 CanLII 42636 (ON CA), 218 O.A.C. 315 (C.A.), at para. 21, leave to appeal refused,  S.C.C.A. No. 92. We see none here.
