Privacy of the Jury
Section 648 prohibits anyone from publishing, broadcasting, or transmitting any part of a trial that occurs outside of the presence of the jury.
Section 649 prohibits any person providing support services to a disabled juror from disclosing any information obtained from the jury while outside of the court.
Jury secrecy does not prevent the admission of fresh evidence including annotations found on transcripts located in the jury room.
Communication with Jurors
Communications between the jury and the court or counsel must be with the presence of the accused.
It is improper for the trial judge to have "private conversations" with potential jurors during selection that is within the earshot of accused counsel but not accused.
Communication between the jury and all the parties in court should not occur through an intermediary such as a sheriff.
Secrecy of jury deliberations is an essential part of the right to trial by jury under s. 11(f).
Where the jury is "deadlocked" and further deliberation would be "useless" the judge has the discretion to discharge the jury and impanel a new jury.
Disagreement of jury
653. (1) Where the judge is satisfied that the jury is unable to agree on its verdict and that further detention of the jury would be useless, he may in his discretion discharge that jury and direct a new jury to be impaneled during the sittings of the court, or may adjourn the trial on such terms as justice may require.
Discretion not reviewable
(2) A discretion that is exercised under subsection (1) by a judge is not reviewable.
R.S., c. C-34, s. 580.
When considering the applicability of a defence it is not necessary for the jury to be in agreement about which elements cause them to reject the defence.

Jury compensation is typically set out by the provincial Juries Act.
The Court's inherent jurisdiction over the trial process permits the Judge to enhance the statutory amount.
Deliberation and Verdict
While the jury is deliberating they must not separate. An officer of the court must keep charge of the jury while together to ensure they do not communicate with anyone outside of the jury without the judge's consent.
Juries can render a verdict any day of the week. The fact that it is a Sunday or a Holiday does not affect the trial process.
Under s. 670, a judgement will not be stayed or reverse solely for the reason of "any irregularity in the summoning or impaneling of the jury" or the "reason that a person who served on the jury was not returned as a juror by a sheriff or other officer."
Under s. 671, a verdict cannot be quashed or impeached only by reason that there was an omission to follow procedure of "qualification, selection, balloting or distribution of jurors, the preparation of the jurors' book, the selecting of jury lists, or the drafting of panels from the jury lists".
A jury is entitled to receive any type of aid that “assists them in dealing with the evidence reasonably, intelligently and expeditiously.” 
A jury may take copies of a slideshow presented in closing by counsel where it is useful and reliable.

Determined Facts After a Jury Trial
724. (1) In determining a sentence, a court may accept as proved any information disclosed at the trial or at the sentencing proceedings and any facts agreed on by the prosecutor and the offender.
(2) Where the court is composed of a judge and jury, the court
- (a) shall accept as proven all facts, express or implied, that are essential to the jury’s verdict of guilty; and
- (b) may find any other relevant fact that was disclosed by evidence at the trial to be proven, or hear evidence presented by either party with respect to that fact.
(3) Where there is a dispute with respect to any fact that is relevant to the determination of a sentence,
- (a) the court shall request that evidence be adduced as to the existence of the fact unless the court is satisfied that sufficient evidence was adduced at the trial;
R.S., 1985, c. C-46, s. 724; 1995, c. 22, s. 6.
The primary principles the court must follow to determine facts subsequent to a jury trial:
- The sentencing judge must determine the facts necessary for sentencing from the issues before the jury and from the jury's verdict.
- The sentencing judge is bound by the express and implied factual implications of the jury's verdict, and must accept as proven all facts express or implied that are essential to the jury's verdict.
- The sentencing judge must not accept as fact any evidence consistent only with a verdict rejected by the jury.
- When the factual implications of the jury's verdict are ambiguous, the sentencing judge should not attempt to follow the logical processes of the jury, but should come to his or her own independent determination of the relevant facts.
- Aggravating facts must be established beyond a reasonable doubt. Other facts must be established on a balance of probabilities.
- The sentencing judge should therefore find only those facts necessary to permit the proper sentence to be imposed in the case at hand. The judge should first ask what the issues on sentencing are, and then find such facts as are necessary to deal with those issues.
It is not necessary for the judge to derive a complete theory of the incident from the verdict. He is "required to make only those factual determinations necessary for deciding the appropriate sentence in the case at hand”
