“As this court said in R. v. Morrissey (1995), 22 O.R. (3d) 514, at p. 524 “…where a case turns on the application of well-settled legal principles to facts as found after a consideration of conflicting evidence, the trial judge is not required to expound upon those legal principles to demonstrate to the parties, much less to the Court of Appeal, that he or she was aware of and applied those principles.” Judges are presumed to know the law.”
