The Canadian jury system has been described as one of the "most familiar symbol and manifestation of the Rule of Law in this country".
The jury brings to the system the "values and insights of ordinary citizens" as well as their "common sense".
A jury's task is not to "reconstruct what happened" but rather to determine if the burden of proof sufficient to make out a conviction has been met.
Courts must ensure that nothing is put before a jury in the form of evidence or argument that would play on any emotions or unfair reasoning, including inflamatory remarks.

R v Roberts (1973), 14 CCC (2d) 368 (ONCA)(complete citation pending), at p. 370 ("It has been said on many occasions that the paramount duty of the Crown prosecutor is to see that justice is done, not to strive for a conviction. Certainly, he ought to refrain from language which is likely to inflame the jury and to divert the jury's attention from the real issue that they have to decide.")
R v Vallieres,  4 CCC 69 (QCCA)(complete citation pending), at p. 82 ("[I]n a trial before a jury, no evidence can be presented, and no statement may be made by counsel for the Crown, which might induce a jury to base a conviction upon psychological or passionate grounds which might affect the most objective and just treatment of the accused, in accordance with cold reason...")
Right to a Jury Trial
Section 11(f) of the Charter provides certain rights to trial by jury:
An offence with a maximum penalty of 5 years less a day cannot be considered a "more severe punishment" due to the existence of some "collateral negative consequences" to the period of incarceration.
Where an offence violates s. 11(f) the appropriate remedy would not be an entitlement to a jury trial, but rather a "reading down" of the offence maximum penalties.
Similarly, s. 471 provides presumption of a right to a jury in all indictable offences:
Jurors bring their own life experience's to their task.
A prospective juror is presumed capable of "setting aside their views and prejudices and acting impartially between the prosecution and the accused upon proper instruction by the trial judge on their duties."
Members of the jury are to come to a unanimous conclusion on the verdict. They do not have to agree on the means or path to that verdict.
R v Peers, 2015 ABCA 407 (CanLII), per curiam (2:1), at para 15 - the court qualifies by suggesting collateral punishment such as "corporal punishment, banishment from the community, forced labour, or revocation of citizenship" may be enough. (aff'd at 2017 SCC 13 (CanLII), per curiam)
