I can only respond in terms of what our statute requires.
Section 23 of the CCRA requires us:
To take all reasonable steps to obtain, as soon as is practicable, (a) relevant information about the offence; (b) relevant information about the person's personal history, including the person's social, economic, criminal, and young offender history; (c) any reasons or recommendations relating to the sentencing or committal that are given or made by the court that convicts, sentences or commits the person, and any court that hears any appeal; (d) any reports relevant to the conviction, sentence or committal that are submitted to the court; and (e) any other information relevant to administering the sentence or committal.
I'm cutting a bit out here, but that's basically it.
