An accused person is entitled to a Constitutional right to an impartial trier-of-fact.
A trial judge has a duty to ensure that the trial is fair and there are no miscarriage of justice.
The trial judge is more than just an umpire but "is not to enter the arena and appear to take on the role of an advocate".
Our criminal justice system is on that is "essentially adversarial" where the Crown presents evidence of guilt and the accused points out weaknesses in the evidence and presents contrary evidence. The trier of fact is a neutral arbiter of the dispute. For this reason it is improper for the judge to usurp the role of counsel in an inquisitorial manner.
Trial judges are presumed to know the elementary principles of law.
See s. 11(d) of the Charter which is the right "...to be presumed innocent until proven guilty according to law in a fair and public hearing by an independent and impartial tribunal;"

Right of Parties to be Heard
There is a fundamental tenant that all parties affected by a decision shall be given an opportunity to be heard by the court before the court makes a ruling. This is the principle of audi alteram partem . The right to be heard also provides a person "the right to know the case to be met".
The judge has an obligation to allow each party who may be affected by a ruling to be permitted to respond to the case against them.
A failure to afford each side to present argument before a judgment is a denial of that right will violate procedural fairness and is fatal.
The right is not unqualified. A declaration of a party as a "vexatious litigant" has the effect of removing this right. Accordingly, it is only used sparingly.
Related to this principle is the common law rule that "a person cannot be deprived of his liberty or property without notice."

Rules of Court
Under s. 482(1) and (2), a superior court and provincial have the power to make rules governing criminal proceedings.
Under s. 482.1, the courts also have the power the makes rules with respect to case management.
- See also Case Management
Hearing Evidence at Trial
However, there is no requirement that the judge "record all or any specific part of the process of deliberation on the facts". A failure to record facts does not give rise to an error unless the judge's reasons demonstrate that not all the facts were considered.
Control over Trial Process
A criminal trial court to "control its process" is a fundamental value of the criminal justice system". A judge has "considerable" powers to intervene in a criminal trial to manage the proceedings.
A judge is authorized to make orders "necessary to ensure an orderly trial, without which the administration of justice risks being ...thrown into disrepute".
A Superior Court Justice has the inherent jurisdiction to eliminate any procedural unfairness that arises during a trial.
The Superior court has inherent jurisdiction to control the disclosure process of a matter before the provincial court.
The "procedural directions contained in the Code are of necessity exhaustive". The powers of a provincial court judge are "entirely statutory." However, "the authority to control the court's process and oversee the conduct of counsel is necessarily implied in the grant of power to function as a court of law. This Court has affirmed that courts can apply a ‘doctrine of jurisdiction by necessary implication’ when determining the powers of a statutory tribunal.” 
The inherent powers of a superior court judge to control the court process is said to be equally available to provincial court judges either expressly by statute or by necessary implication.
Consequently, a provincial court judge has implied jurisdiction to "vary one of its own orders in order to correct clerical mistakes or errors arising from an accidental slip or omission or in order to properly reflect the intention of the court"
Generally, a "court has a limited power to reconsider and vary its judgment disposing of the case as long as the court is not functus.”
Exclusion of Evidence
There is a limited power of a trial judge to exclude evidence in order to ensure trial fairness where other remedies are not sufficient. However, it is considered an "unusual exercise" of the trial management power. 
Prohibition Orders on Defence Conducting their Defence
A judge may limit the examination or cross-examination of witnesses or the right to call defence witness only where it is justified in "clear and compelling circumstances".

The judge is required to listen to evidence that "advances the work of the court". He or she cannot be required to listen to irrelevant or pointless evidence. The judge may even disallow the submission of non-relevant evidence.
The judge has an obligation to track the admission of evidence to ensure that the record is restricted to what is admissible, and also that it is only used for the purpose for which it was admitted.
The judge has the jurisdiction to edit the evidence, including written statements and oral testimony, as it is given. The judge may edit out portions of the evidence that is prejudicial or otherwise irrelevant or immaterial only so long as it does not distort the probative evidence.

Sitting Position of Accused
Independent Research of the Judge
A judge should not enter "into the fray" by doing self-directed research that puts them in a role of being "advocate, witness and judge".
A judge can only rely on social studies, literature or scientific reports after they have been tested by the parties.

Loss of Judge During Proceedings
Doctrine of Functus Officio
Communications with Counsel Out of Court
Ex parte communications (i.e. communications in absence of one of the parties) concerning an ongoing proceedings should be avoided. It is a rule that relates to the "public perception of fairness within the administration of justice".  It also preserves "confidence of the public in the impartiality of the judiciary and thereby in the administration of justice".
Ex parte communications between judge and counsel concerning a case will "almost invariably raise a reasonable apprehension of bias".
Duty to Make a Record
Under Part XX of the Code, there is a duty upon the court to keep a record of every arraignment and all proceedings after the arraignment.
Record of Proceedings
624. (1) It is sufficient, in making up the record of a conviction or acquittal on an indictment, to copy the indictment and the plea that was pleaded, without a formal caption or heading.
Record of proceedings
(2) The court shall keep a record of every arraignment and of proceedings subsequent to arraignment.
R.S., c. C-34, s. 552.
Endorsements on the Information
Where an election is made to supreme court, either judge alone or judge and jury, the court must endorse the information showing the "nature of the election" and whether anyone requested a preliminary inquiry.
Where an election is made to provincial court before a provincial court judge, the court must endorse the information with that election.
Intervention During Examinations
There is a presumption that a trial judge has intervened in a trial properly. The judge may often make comments, give directions or ask questions.  There is also a strong presumption against 
Merely intervening frequently, by itself, it not enough to amount to a miscarriage of justice.
A judge may disrupt questioning in order to clear evidentiary ambiguities, pursue subjects left vague by the witness, and ask questions counsel should have asked.
"Interlocutory remarks" of the judge during argument are not "judicial pronouncements"
The presence or absence of objections by defence counsel is a factor but not determinative.
A judge is permitted to give the jury mid-trial instructions to disregard any erroneous comments made by counsel. If it is given promptly and with explanation of why it should be disregarded, this can effectively correct any concern that a jury might misuse the information. 
There is a presumption that an accused not be restrained while in court. It is upon the Crown to establish grounds to order the restaint of the accused.
Unnecessary and repeated interruptions that disrupt the flow and effectiveness of cross-examination may exceed permissible limits. A judge should generally only ask questions after the examination is complete.
The judge is entitled in:
- posing questions to a witness to clear up ambiguities in their evidence;
- calling a witness to order and focusing him or her on the true matters in issue;
- exploring some issue on which the witness’s evidence has been left vague and uncertain; or
- putting questions which should have been asked by counsel in order to elicit evidence on some relevant issue.
The judge should not usurp the role of counsel or interfere with the defence.
Judges may pose any questions to the witness where it is in the interest of justice.
Judges should not interfere in a manner that undermines the function of counesl and disrupts or destroys counsel's strategy.
Crown counsel is permitted present its evidence and question its witnesses even where the relevancy is not immediately apparent to the judge.
Both defence and crown must be permitted to present their case before a decision is made.
The main issue is not whether the intervention was such that a "reasonably minded person who had been present throughout the trial could conclude that the accused had not received a fair trial, but whether such a person would come to such a conclusion."

Preserving order in court
484. Every judge or provincial court judge has the same power and authority to preserve order in a court over which he presides as may be exercised by the superior court of criminal jurisdiction of the province during the sittings thereof.
R.S., 1985, c. C-46, s. 484; R.S., 1985, c. 27 (1st Supp.), s. 203.
This section permits a judge to make an order of contempt for:
- persistent refusal of accused to stand on entry of the presiding judge.
- the use of recording devices in the court against the order of the judge.
- the high degree of intoxication of the accused appearing at trial
This section cannot be used to order the mode of dress of counsel.

Superior Court Inherent Jurisdiction
All Courts that are created by s. 96 of the Constitution Act, 1867 are vested with "inherent jurisdiction" to make orders on matters that are not necessarily authorized by statute.
The doctrine is available as a "residual source of powers" that is available to a judge "whenever it is just or equitable to do so", which includes:
- ensuring "the observance of due process of law";
- preventing "improper vexation or oppression";
- "do justice between the parties" and
- securing "a fair trial" between the parties.
It can be used to "supplement under-inclusive legislation or to otherwise fill gaps in appropriate circumstances".
The doctrine may be limited by statute. It cannot be used in such a way that it contravenes any statutory provision.
It is also limited by "institutional roles and capacities that emerge out of our constitutional framework and values".
It generally should be exercised "sparingly and with caution", such as where "inferior tribunals are powerless to act act and it is essential to avoid an injustice that action be taken."
R v Caron, 2011 SCC 5,  1 SCR 78 at para 21 (These powers are derived "not from any statute or rule of law, but from the very nature of the court as a superior court of law" to enable "the judiciary to uphold, to protect and to fulfil the judicial function of administering justice according to law in a regular, orderly and effective manner".)

Doctrine of Mootness
Under the doctrine of "mootness" suggests that a court may decline to decide a case that "raises merely a hypothetical or abstract question" that "will not have the effect of resolving some controversy which affects or may affect the rights of the parties".
A judge found to be sleeping during trial will affect trial fairness and warrant a retrial.
