Mere identification of discrepancies in the Crown case or matters capable of cross-examination, even if not drawn to the attention of the court below, does not justify withdrawal of a guilty plea. The error in advice must be one that affects the integrity of the plea — that is, the genuineness of the confession of guilt. Errors going only to the likely outcome of a contested trial or the credibility of Crown witnesses are insufficient. The focus is on whether the plea represents a genuine consciousness of guilt, not on whether the accused might have been acquitted.
