The Crown's role as a "minister of justice" must enforce the laws of the jurisdiction.
It is improper for the Crown to be selective as to which laws they wish to enforce except when exercising discretion in a particular case.
Both Crown and defence have a "responsibility in providing relevant case law to assist the court".
The role of the prosecuting Crown is "quasi-judicial".
Nevertheless, prosecutions are to be undertaken with "earnestness and vigour".
The prosecutor "always has a discretion in prosecuting criminals to the full extent of the law".

Bain, supra ("[A prosecutor's duty is] to see to it that every material point is made which supports the prosecution case or destroys the case put forward for the defence. But as prosecuting Counsel he should not regard his task as one of winning the case. He is an officer of justice. He must present the case against the prisoner relentlessly, but with scrupulous fairness.")

The Crown includes victim services. However, disclosure obligations are not implicated in the records of victim services as the prosecutor does not have knowledge or control over those materials.

Section 2 of the Code defines "prosecutor":
“prosecutor” means the Attorney General or, where the Attorney General does not intervene, means the person who institutes proceedings to which this Act applies, and includes counsel acting on behalf of either of them;

The Crown Attorney
The Crown Attorney is invested with the authority to conduct prosecutions on behalf of the Director of Public Prosecutions for the province or Federal government.
The choice of who is to prosecute an accused person is part of the Attorney General's core prosecutorial discretion and is not reviewable short of an abuse of process. 
The Crown's role is to "assistant to the Court in the furtherance of justice, and not to act as counsel for any particular person or party".

The Attorney General
The Attorney General's role is to represent the public interest in criminal prosecutions.
The AG derives its power from its role as advisor to the Crown.
In the UK, the Attorney General never sits in cabinet, however, is Canada the AG will always be part of government. As a result, the independence of prosecutions is even more important than in the UK.
Only Criminal charges under the Criminal Code may be prosecuted by the Attorney General of provincial government. Violations of other federal acts, such as the food and drug act, may be prosecuted by Attorney general of Canada.
For the purposes of all federal acts involving criminal law except those in the Criminal Code, the "Attorney General" refers to the Attorney General of Canada and their agents. Provincial attorney general is excluded from having authority over such matters.
The Attorney General of Canada may prosecute conspiracy charges under the Criminal Code. 
Where there is an absence of involvement of federal prosecutors, there can be authority for the provincial Attorney General to prosecute.

Attorney General of Canada
Powers of the Attorney General of Canada
467.2 (1) Notwithstanding the definition of “Attorney General” in section 2, the Attorney General of Canada may conduct proceedings in respect of
- (a) an offence under section 467.11 or 467.111; or
- (b) another criminal organization offence where the alleged offence arises out of conduct that in whole or in part is in relation to an alleged contravention of an Act of Parliament or a regulation made under such an Act, other than this Act or a regulation made under this Act.
For those purposes, the Attorney General of Canada may exercise all the powers and perform all the duties and functions assigned to the Attorney General by or under this Act.
Powers of the Attorney General of a province
(2) Subsection (1) does not affect the authority of the Attorney General of a province to conduct proceedings in respect of an offence referred to in section 467.11, 467.111, 467.12 or 467.13 or to exercise any of the powers or perform any of the duties and functions assigned to the Attorney General by or under this Act.
1997, c. 23, s. 11; 2001, c. 32, s. 28; 2014, c. 17, s. 11.
Purpose of Prosecution
The role of the crown is not to secure convictions, it's role is to present to a trier of fact evidence that is considered credible and relevant to the alleged offence. It is to "promote the cause of justice" and not to persuade a trier of fact "to convict other than by reason". The Crown's job includes seeking the truth. However, it does not mean seeking justice for a complainant.
The Crown is expected to "present, fully and diligently, all the material facts that have evidentiary value, as well as all the proper inferences that may reasonably be drawn from those facts." The use of rhetorical techniques to distort the evidence or to present misleading and highly prejudicial statements are inappropriate.
The prosecution of offences is not a contest between the crown and the accused. It is an investigation to determine the truth. It should be done without any feelings of animus.
Nevertheless, the Crown may still "act as a strong advocate within the adversarial process. ...it is both permissible and desirable that it vigorously pursue a legitimate result to the best of its ability."
The decision to prosecute is solely in the authority of the crown and should only be reviewable in the clearest of cases.
It is not necessary for the Crown to personally believe in a person's guilt to proceed on charges.
It is possible for the Crown to avoid a subpoena to provide evidence justifying the basis for exercising their discretion, such as in a corner's inquest. However, a subpoena to attend a commission inquiry to explain their actions will be enforceable.
The Crown's advice on the form charges cannot be reviewable except as a possible abuse of process.
The powers of the prosecutors include the "power to charge multiple offences".
Where alleged "conduct constitutes an offence under more than one section of the Code, the Crown has a discretion with respect to the offence for which the accused is to be prosecuted".
Historically, the Crown Counsel was not responsible for making recommendations on penalty in a sentencing hearing.

Discretion of Crown
Relationship with Police
The crown must remain separate from the police.  The Crown and police are to consult with each other but the "maintenance of a distinct line between these two functions is essential to the proper administration of justice."
The Crown can be liable for their part in giving advice to police during an investigation.
While it is acceptable, the Crown should not try to be involved in interviews with parties prior to charges being laid.

- R v Regan, 2002 SCC 12,  1 SCR 297 at 61-70
Negotiations with Defence
The Crown is permitted to negotiate charges, by offering to drop certain charges that are supported by evidence, in exchange for guilty pleas to others.  By inference, it may be improper for the Crown to use charges unsupported by evidence as part of bargain. There is also a requirement that the defence be in possession of a "substantial" portion of the disclosure so that an informed decision can be made.
A plea deal worked out between a particular Crown Attorney and defence counsel may have a binding effect on the Crown on other cases.
Judge shopping is where counsel attempts to influence which judge will hear a particular matter. Judge shopping by crown counsel is not acceptable as it suggests that the system is partial.

R v Pilarinos 2001 BCSC 1690 (CanLII) at para 126 ("The principle is clear – judge shopping by Crown counsel is not acceptable in our system of justice. I will return to this issue when I discuss the evidence in this case.")
Non-Appearance of Crown
Non-appearance of prosecutor
(4) Where the prosecutor does not appear at the time and place appointed for the resumption of an adjourned trial, the summary conviction court may dismiss the information with or without costs.
(5) to (8) [Repealed, 1991, c. 43, s. 9]
R.S., 1985, c. C-46, s. 803; 1991, c. 43, s. 9; 1994, c. 44, s. 79; 1997, c. 18, s. 112; 2008, c. 18, s. 45.
Crown's should not call witnesses that give evidence that they knew or should have known were lying.
The Crown has an ethical obligation "to ensure that an accused person is not denied a fair trial as a result of their words or deeds". However, it is not to say that Crown counsel cannot "be forceful during closing argument" that may "jeopardize the accused's right to a fair trial".
Obligation to Call Witnesses
Guidelines on the preparation of witnesses by crown include:
- Counsel should not discuss evidence with witnesses collectively
- It witnesses memory should be exhausted through questioning before any references are made to conflicting evidence
- Witnesses recollection should be recorded by counsel. Sometimes it should be done in the presence of a third-party or police officer.
- Question should not be suggestive
Inappropriate preparation and communication with witnesses may contaminate the residence and produce a mistrial.
- R v Spence, 2011 ONSC 2406 (CanLII)
- R v Spence, ibid.
Agreements made by a Crown Attorney is binding upon the Attorney General. Their word is to be relied upon. Thus, if a subsequent Crown were to repudiate an agreement could be an abuse of process.

R v Hardick  NSJ No. 305(*no link) - charges stayed
Abuse of Process
Intervention by the Crown in a collateral case is to be done "sparingly" or "rarely". Granting intervener status may result in unfairness or appearance of unfairness without adding much to the content of the submissions.
When Attorney General does not stay proceedings
579.01 If the Attorney General intervenes in proceedings and does not stay them under section 579, he or she may, without conducting the proceedings, call witnesses, examine and cross-examine witnesses, present evidence and make submissions.
2002, c. 13, s. 47.
Intervention by Attorney General of Canada
579.1 (1) The Attorney General of Canada or counsel instructed by him or her for that purpose may intervene in proceedings in the following circumstances:
- (a) the proceedings are in respect of a contravention of, a conspiracy or attempt to contravene or counselling the contravention of an Act of Parliament or a regulation made under that Act, other than this Act or a regulation made under this Act;
- (b) the proceedings have not been instituted by an Attorney General;
- (c) judgment has not been rendered; and
- (d) the Attorney General of the province in which the proceedings are taken has not intervened.
Section 579 to apply
(2) Section 579 applies, with such modifications as the circumstances require, to proceedings in which the Attorney General of Canada intervenes pursuant to this section.
1994, c. 44, s. 60.
Conduct in Trial
Theory of the Case
A Crown does not need to "particularize" as to the manner in which a crime is alleged to have been committed. There is some "fluidity" allowed to the Crown chancing the theory "to accommodate changes in the evidence", including changes arising from the accused testifying.
The Crown is not obliged to prove "particulars" that are given orally at the opening of a trial.
A mistrial can be found where the Crown, at the end of its case, stays the charges against a co-accused, effectively changing its theory of the case.
