Reasons need not be elaborate in a brief trial

R. v. P.S. 2013 ONCA 297 is a useful source for the proposition that, in brief trials, a trial judge's reasons need not be elaborate to be sufficient:

[3] Second, the appellant argues that the trial judge failed to assess the reliability of the testimony of Cormier and Joamie before accepting their evidence. We do not agree with this argument. This was a short trial and, in the circumstances of this case, it was unnecessary for the trial judge to expressly analyze the reliability of the evidence of these two witnesses before accepting it.
