In F.H. v. McDougall, released October 2, 2008, the Supreme Court of Canada has confirmed that there is only one standard of proof in a civil case: proof on a balance of probabilities. A mixed series of cases over the last 50 years had caused uncertainty as to the applicable standard of proof when trying allegations of morally blameworthy conduct, for example, of fraud, of sexual assault in the civil context or of dishonesty in the context of professional conduct by lawyers (see for example Bater v. Bater, [1950] 2 All E.R. 458 at 459 (C.A., Lord Denning); H.F. v. Canada (Attorney General), [2002] B.C.J. No. 436, 2002 BCSC 325 at para 154; R. v. Oakes, [1986] 1 S.C.R. 103 at 138; Continental Insurance Co. v. Dalton Cartage Co., [1982] 1 S.C.R. 164 at 169-171). What had evolved was an apparently sliding scale, sometimes requiring plaintiffs to meet a higher standard of proof, a standard often said to be commensurate with the occasion. That uncertainty is now resolved, perhaps finally.
