McCarthy Tétrault LLP v. Guberman, 2012 ONCA 679, released today, has clear language upholding the general rule that clients will be given a right to assess a lawyer's account:
 The right of a client to have a lawyer’s account assessed is an important one, not to be taken away except in compelling circumstances. As this court has stated, public confidence in the administration of justice requires the court to intervene where necessary to protect the client’s right to a fair procedure for the assessment of a solicitor’s bill: see Price v. Sonsini (2002), 215 D.L.R. (4th) 376, at para. 19.
