The purpose of a jury charge is to "educate the decision-maker so that it will make an informed decision, not to tell the decision-make what decision to make".
An accused person is "entitled to a properly, not perfectly, instructed jury".
Judges are afforded some flexibility in the language they use in a jury instruction.
It is through the "instructions that the jury must appreciate the value and effect of the evidence in the context of the legal issues."
A jury charge must be "even-handed" and the instructions "fair and balanced." At no time should sides be taken or editorial comments made.
The charge should not be a "partisan broadcast".
A judge may never direct the jury to find an element proven in light of the evidence at trial. This error cannot be cured by s. 686(1)(b)(iii).
A new trial is not warranted unless there is a "realistic possibility" that the instructions, within the context of the charges as a whole and the positions of the parties, may have misled the jury.
Instructions are not to be reviewed "to determine the extent to which they adhere to or depart from some particular approach or specific formula". Rather, they must be examined "against their ability to fulfill the purpose for which those instructions are provided."
A failure to object to a jury charge "affords some evidence" to suggest that the charge was not unfair, incomplete or unbalanced. The evidence will especially persuasive where "counsel has had ample opportunity to review draft of proposed instructions and ample time to offer suggestions for inclusions, deletions and improvements". 
The instructing judge is responsible for "review of the evidence and ... to relate the evidence to the position of the defence"
An instructing judge "must set out in plan and understandable terms the law that the jury must apply when assessing the facts".
The "final instructions must leave the jury with a clear understanding of the factual issues to be resolved, the legal principles governing the factual issues, the evidence adduced at trial, the position of the parties and the evidence relevant to the positions of the parties on those issues".
When reviewing the quality of instructions the judge "must not proceed on the assumption that jurors are morons, completely devoid of intelligence and totally incapable of understanding a rule of evidence".
Except in rare circumstances, the "trial judge must review the substantial parts of the evidence and give the jury the position of the defence so that the jury can appreciate the value and effect of the evidence"
Review of evidence should include not simply summary of witness evidence but also available exhibits.
The trial judge should not share his evidence notes to the judge even if both counsel find it acceptable.
A decision tree given to the jury by the instructing judge does not constitute part of the instructions. It is a deliberative aid.
The use of annotations on the decision tree to indicate the burden and standard of proof has been suggested as being "helpful".
It is presumed that juries act reasonably in their verdict, are able to absorb the "gist" of the judge's instructions, and are able to follow them.
In appellate review of instructions, the issue is whether "in the context of the whole charge" whether there is a "reasonable possibility that the trial judges erroneous instructions may have misled the jury into improperly applying the [legal standard]".
Evidence misleading the jury can come for sources including the matters bought up in post-charge instructions and questions from the jury.
Model jury instructions are meant to be a sample from which adjustments can be made to craft appropriate jury insturctions for a particular case.

Components of a Jury Instruction
A recommended instruction should generally include some basic components such as:
- an explanation on the presumption of innocence;
- an explanation of the burden of proof; and
- an explanation of how to assess credibility and reliability of witnesses' testimony.
Any good instruction should include at least five components:
- the legal framework, typically the elements of the offence or offences with which the accused is charged;
- the factual issues arising out of the legal framework that the jury must resolve;
- the material evidence relevant to these issues;
- the position of the Crown and defence on these issues; and
- the evidence supporting each of their positions on these issues.
The jury should be able to appreciate "the value and effect of that evidence, and how the law is to be applied to the facts as they find them".
Elements of Clarity
The instructions must give the jury a clear understanding of:
- the factual issues to be resolved;
- the legal principles governing the factual issues and the evidence adduced at trial;
- the positions of the parties; and
- the evidence relevant to the positions of the parties on the issues.

R v Daley, 2007 SCC 53 (CanLII), per Bastarache J, at para 29
Before beginning deliberations, the judge will hold a pre-charge conference where the parties will provide input on the form of the charge.
Pre-charge conference should be held in the presence of the accused and on the court record.
An agreement on instructions at the pre-charge conference, which includes an absence of objection, that are reflected in the trial judge's instructions is a "significant factor" in assessment the adequacy of the instructions on appeal. 
- see s. 650.1
- R v Simon 2010 ONCA 754 (CanLII)
- R v Bouchard, 2013 ONCA 791 (CanLII)
Once the jury has been charged, the jury is directed to "retire" to decide on the issues befor them.
Where there are more that 12 jurors, the judge will perform a random draw of juror names to have them discharged until there are 12 remaining.
- s. 652.1(1) states ("After the charge to the jury, the jury shall retire to try the issues of the indictment."
- see s. 652.1(2) for details on the process
Standards of Proof
Where the jury asks a question clarifying the meaning of reasonable doubt. The judge should not simply reiterate the standard of proof instructions, but should explain the difference of the standard of "balance of probabilities" and "proof beyond all doubt".
When reviewing the instructions on the standard of proof the question is "in the context of the whole charge", whether there is a "reasonable possibility that the trial judge's erroneous instruction may have misled the jury into improperly applying the reasonable doubt standard".
It is not necessary that the jury be explicitly told that "reasonable doubt" is "much closer" to absolute certainty than proof on balance of probabilities.
When reviewing the standard of proof beyond a reasonable doubt on a case that turns on identity, it important to couch the instructions "in terms of the frailties of eyewitness identification".

A judge is permitted but not obligated to "outline the inferences that may or may not be available from some circumstantial evidence adduced at trial". There is no need to "catalogue all available inferences" from each piece of evidence. It is only obligation for the judge on circumstantial evidence to "clearly" explain the necessity of finding guilt beyond a reasonable doubt and how there may be more than one way to achieve the objective.

Instructions that direct the jury to presume any incriminating parts of an accused's statement are likely true, while exculpatory statements carry less weight are known as "Duncan instructions" and should be avoided as they tend to confuse the jury.
- R v Illes, 2008 SCC 57 (CanLII)
Effect of Multiple Complainants
Where there are multiple complainants each associated with different counts and no similar fact application has been made, the judge should give limiting instructions on the use of the evidence. The judge should remind the jury that they may not use evidence relating to a particular count to determine if another count is made out. They future cannot use any of the evidence to establish bad character and a greater likelihood that the accused is guilty.
Reviewing the Evidence
A trial judge must review the evidence for the jury so that they can appreciate how the law is applied to the facts that they find.  The review should be of "substantial parts" of the evidence in order to "relate it to the issues that the jury is or may be required to decide so that the jury appreciate the nature and effect of the evidence and its relationship to the defence advanced".
Substantial Review and Relating it to Issues
There is no obligation to review all of the evidence at trial, it need not be exhaustive. Also a failure to mention items of evidence will not be fatal where the omission did not constitute the sole evidentiary foundation for a defence. The extent of the review will vary from case-to-case.
There is "considerable latitude" in reviewing the evidence and relating it to the issues for the jury.
A simple "serial review" of the evidence is considered unhelpful to the jury and does not do much to "relate the evidence to the issues".
The key part of a judge's duty is to review the "substantial parts of the evidence" and explain the position of the defence to the jury. The judge should relate the evidence to the positions of the parties by reviewing the "substance of the evidence that bears on each issue and indicating to the jury which parts of the evidence support each party’s position".
In giving the instructions, the judge must relate the evidence heard at trial to the issues raised by defence. This involves first reviewing the evidence and then relating it to the position of the defence so that the jury understand the "value and effect" of the evidence.  A judge will often indicate which parts of the evidence supports each parties position on particular issues.
A jury charge should not be reviewed in isolation, but rather in light of the evidence and closing arguments of counsel.
It has been suggested that a acceptable review of the evidence related to the issues was organized for each issue as:
- identified the issue;
- explained the legal requirements of proof;
- summarized the essential features of the evidence that were relevant for the jury to consider in deciding the issue;
- reiterated the Crown’s burden of proof on the issue; and
- described the consequences of the available findings on the issue for further deliberations and for the verdict.
Strong Crown Cases
In overwhelming Crown cases, the judge does not need to ignore evidence that implicates the accused to create a balanced charge, nor does he have to "spin a web of exculpatory inferences" that stretch the available conclusions. This is particularly applicable where the defence argument is simply that the evidence does not meet the standard of proof.
The constitution requires that even when the evidence is "overwhelming" the judge cannot direct the jury to convict.

This affirmed the right to "jury nullification"
A judge is permitted to provide specific warnings to the jury on certain issues of which they may not be aware of their significance. Warnings or cautions are not given because the jury is seen an uninformed or unintelligent, but rather to give them knowledge from judicial experience. The warning concerns knowledge beyond the obvious that they can discern themselves. The purpose is to “help the jury appreciate the peculiarly concerning qualities of evidence which must be evaluated with particular caution in light of those concerns”
Limited Purpose Evidence
Generally, evidence of limited admissibility must be accompanied by specific jury instructions that satisfy the following:
- identify the evidence to which they apply;
- explain the permitted use of the evidence; and
- explain the prohibited use of the evidence.
This includes evidence admitted such as bad character evidence.
A judge must provide limiting instructions on the use of prior statements of witnesses. Without instructions there is a risk that jurors "may not be aware that they cannot use such statements as substantive evidence, irrespective of the use made of the statements by counsel." We cannot safely assume jurors understand the purpose of such evidence. 
Failure to give the instructions is an error of law. The issue for the appellate court on such an error is whether "any convictions ... can be sustained despite the error of law. Convictions may be upheld providing the error did not cause a substantial wrong or miscarriage of justice".

R v M.T., at para 85
To illustrate the frailties of identification evidence, a judge should not instruct a jury to close their eyes and attempt to accurately picture the person next to them.
Due to the dangers of bolstering a witnesses credibility through prior consistent statements, "a limiting instruction will almost always be required where such statements are admitted." The instruction should delineate that "consistency is not the same as accuracy" and should not be used to assess general reliability.
Submissions and instructions suggesting that a hearsay statement should be relied upon for a verdict can warrant a new trial.
Only where there is an "air of reality" that the evidence can make out the requirements of the defence. The evidential foundation does not exist where "its only constituent elements are of a tenuous, trifling, insignificant or manifestly unsubstantive nature: there must be evidence in the record upon which a properly instructed jury, acting judicially, could entertain a reasonable doubt as to the defence that has been raised."Or to put it another way, the test does not consider whether a defence is likely, somewhat likely, unlikely, or very likely. It only considers whether "there is some evidence that puts the defence in play".
An accused "should not lightly be deprived of the chance to present the defence they are relying upon, and the trier of fact can deal with the deficiencies when examining the defences of their merit.”
Even with the defence theory is inconsistent to a particular defence, such as self-defence, but the evidence presents a "coherent route…that could lead to an acquittal" on the basis of that defense that it must be put to the jury.
A charge wil not be "unfair or unbalance" only because the "trial judge did not spend an equal time reviewing the parties' evidence.
Rhetorical questions are generally undesirable in the instructions as it may tend to show some bias.
- R v Baltovich 2004 CanLII 45031 (ON CA), (2004), 73 O.R. (3d) 481, at para 146 ("[Rhetorical questions] should be avoided in the jury charge, lest the trial judge be seen as taking up the Crown's cause and casting off the mantle of objectivity.")
It generally prohibited for the jury to be told about the penalties associated with the charge. They are not to concern themselves with it.

Instructions During Deliberations
Where the jury is deadlocked the judge may give an exhortation to encourage the jury to make effort to reach agreement. The judge must be careful and balanced during the exhortation to a deadlocked jury. The jury will likely be frustrated and disgruntled and so must be handled appropriately.
The judge should not do anything that may treat particular jurors as misunderstood or that pits one jurors against the others. 
It is not relevant to examine whether the jurors were affected by any of the instructions of the judge.
The judge must make it clear to the jury throughout his instructions that they are "not obliged to render a verdict" if they cannot reach a consensus.
During the deliberations of a jury, they are permitted to submit questions to the court and counsel. Jury questions indicate some of the problems the jurors are having in deliberating and seek help from the trial judge.
Answers to questions carry "an influence far exceeding instructions given".
Where a jury question is unclear, the judge should seek clarification before attempting to provide an answer.
Jury questions must be answered "clearly, correctly and comprehensively".
A proper answer should improve the jury’s “understanding of the particular aspects of the evidence that bear on their decision on each essential issue in the case.”
However, the response should be timely as well. Delay without instructions the jury to cease deliberations where the question reflects a misunderstanding is open to risk of corrupting the verdict.
A judge should not communicate with the jury by sending notes with unsolicited information without the input on counsel.
Any errors in a response to a jury cannot be remedied simply by referring back to the correctness of original charge.
An answer should never discourage further questions on any subject.
In responding to a jury question, it is often advisable that the judge invite the jury to return with further questions if the response does not assist.
It is an inadequate answer to respond "yes" to the jury question that I asked "do we consider all of the evidence for all charges?".
A question may find it necessary to "instruct the jury in a manner that does not accord with the theory advanced by either Crown or defence counsel". This is permissible because the jury is not bound by the opposing theories of Crown and defence. However, limitations exist on this flexibility for the purpose of preserving trial fairness.

Failing to Answer Jury Questions
Where a jury asks a question and then withdraws before it is answered by the judge will not render the verdict invalid. The judge need not answer the question for the jury.
A jury may withdraw a question simply by announcing it is ready to give a verdict.
It may be recommended that once the jury is ready despite not having the question answered, that the court canvas both counsel and the jury about whether the question should still be answered.
Recharge of Jury
The answer may result in a "recharge" of the jury. These recharges "must be correct and comprehensive no matter how exemplary the original charge may have been".
An error in recharge cannot be forgiven simply because the original charge was correct. In fact, the more time that passes between the original charge and recharge, the greater imperative that the recharge be "correct and comprehensive".

- R v S. (W.D.), at pp. 530-531
- R v S. (W.D.), at p. 531
Errors in Instructions
Instructions must be "fair and balanced".
A fair instruction requires that "the charge explain the theories of each side and review the salient facts in support of those theories.
The appropriateness of instructions must be analyzed "as a whole and its overall effect".
Where instructions are given on a point of law, the reviewing court should look at the instructions as a whole and consider whether the jury would not have understood the law correctly.
Repetitions of instructions on law correctly may remedy a single instance of an incorrect instruction.
A failure to give instruction on an issue can be a "non-direction amounting to a misdirection".
A charge should not be "endlessly dissected and subjected to minute scrutiny and criticism".
Closing arguments of counsel cannot have the effect of making inadequate instructuon become adequate and do not relieve the trial judge of thier uties in giving instructions..

An appellate court should assess a jury charge functionally. It is not an idealized approach considering whether better instructions could have been given.
Misdirection of a jury (not including non-direction of a jury) is a question of law.
The adequacy of jury instructions "require a functional approach based on the evidence at trial, the live issues raised and the submissions of counsel."
The reviewing judge should determine whether the accused, based on the review of the whole charge, has had a fair trial. It is not to look for minute errors. 
The Court should consider whether the instructions had the ability to fulfill their purpose and not simply whether they diverted from a formula.
All defences that have an air of reality are to be put to the jury, even if not raised by counsel. 
Evidence that the jury had demonstrably not followed the jury instructions will cause a miscarriage of justice.

Standard of Review on Appeal
Whether a judge erred in misdirecting or failing to direct a jury is reviewed on a standard of correctness.
