The Crown must disclose all materials and information that is in its possession or control that is not clearly irrelevant, regardless of if the evidence is to be called at trial or is inculpatory or exculpatory.
The right to disclosures premised upon (1) the right to know the case to meet and (2) the right to make full answer in defense of an offence charged.
When the Crown receives evidence it is not information that it holds in trust for the witness, rather it is "property of the public, to ensure that justice is done."
The right to disclosure is "among the most important and fundamental rights guaranteed to an accused in the criminal process".
The right is guaranteed by the right to full answer and defence under s. 7 of the Charter.
There is also a common law duty to provide "full and fair disclosure is a fundamental aspect of the Crown's duty to serve the Court as a faithful public agent, entrusted not with winning or losing trials".
The obligation also arises from "the premise that material in possession of the prosecutorial authorities that is relevant to a criminal prosecution is not the 'property' of the Crown, but is rather 'the property of the public to be used to ensure that justice is done'"
This right is found codified under s. 650(3) and s. 802 of the Criminal Code which state:
To make defence
(3) An accused is entitled, after the close of the case for the prosecution, to make full answer and defence personally or by counsel.
R.S., 1985, c. C-46, s. 650; 1991, c. 43, s. 9; 1994, c. 44, s. 61; 1997, c. 18, s. 77; 2002, c. 13, s. 60; 2003, c. 21, s. 12.
Right to make full answer and defence
802. (1) The prosecutor is entitled personally to conduct his case and the defendant is entitled to make his full answer and defence.
R.S., c. C-34, s. 737.
The Crown has an obligation to obtain from an investigative agency any relevant information that it is aware of and must "take reasonable step to inquire about ...relevant information".
The duty to make disclosure creates a duty upon the crown to obtain the disclosure from the police and, likewise, the police have a corresponding duty to provide disclosure to the crown. 
These obligations are jointly held by both Crown and police.
The "Stinchcombe disclosure regime" only applies to "material relating to the accused’s case" that are "in the possession or control" of the Crown.
When confronted by a "pure fishing expedition", the Crown has no obligation to discover or disclose records.
Police records from an unrelated file that is not in possession of the prosecuting Crown is not subject to first-party disclosure.
The right does not distinguish between inadmissible and admissible evidence.
The Crown should advise a self-represented accused of the right to disclosure. The judge should not take a plea until satisfied that the accused has been notified.
The doctrine of the "case-to-meet" is a fundamental requirement of a fair trial. It is protected by the common law and the Constitution.

First-Party Disclosure Principles and Obligations ("Stinchcombe")
The Martin Committee produced a report considering the decision. The report detailed the principles of the case, at p. 146:
- The fruits of the investigation which are in the possession of the Crown are not the property of the Crown for the use in securing a conviction, but, rather, are the property of the public to ensure that justice is done. Stinchcombe, at para 12
- The general principle is that all relevant information must be disclosed, whether or not the Crown intends to introduce it in evidence. The Crown must disclose relevant information, whether it is inculpatory or exculpatory, and must produce all information which may assist the accused. If the information is of no use, then it is irrelevant and will be excluded by Crown counsel in the exercise of the Crown's discretion, which is reviewable by the trial judge.
Satisfaction of the obligation to disclosure must be read in context and does not have to be "perfect".
Identity of Crown
In the context of all first party or Stinchcomb disclosure issues, the term "Crown" refers only to the "prosecuting crown" and not all crown entities including police. All Crown entities other than the "prosecuting crown" are considered "third-parties". 
R v Dunn,  OJ No 5749 ("Dislcosure must be considered within this context. It does not have to be perfect, but it does have to be fundamentally fair and sufficient to allow an accused to exercise his or her constitutional right to make full answer and defence.")

Elkins at para 27
Jackson at para 80
Quesnelle at para 11
McNeil at para 22
Preservation of Evidence
Stinchcomb obligation also requires the Crown to preserve all relevant evidence.
At common law, there is a principle of “Omnia praesumuntur contra spoliatorem” that suggests that a party who destroys documents must rebut the presumption that the documents were unfavourable to their case.
Sufficiency for Election and Plea
Initial disclosure should be provided before the accused should be required to make election and plea. This is so that the accused can make an informed decision at "all fundamental steps that affect his rights in a crucial way". Many tactical factors can come into play that would influence the choice of manner of trial.

(3d) 33 (Ont.C.A.), ("Initial disclosure must occur sufficiently before the accused is called upon to elect or plead so as to permit the accused to make an informed decision as to the mode of trial and the appropriate plea. In a perfect world, initial disclosure would also be complete disclosure. However, as is recognized in Stinchcombe, supra, at p. 343 S.C.R., p. 221 C.R.R., p. 14 C.C.C., the Crown will often be unable to make complete disclosure at the initial stage of the disclosure process")

e.g. R v Black, 1998 CanLII 5042 (NS SC) - judge lists tactical factors that come into play in making election
Delaying and Withholding Disclosure
The entitlement to disclosure "is neither absolute or unlimited".
Where disclosure is delayed or withheld is it the burden of the Crown to justify it.
The Crown has a limited discretion to delay disclosure in "rare circumstances" in order "to protect the integrity of an ongoing investigation". Or where it is necessary to protect the safety of certain witnesses.
The Crown also has discretion to determine the most effective manner in which to produce disclosure.
A great amount of deference should be given to the manner and timing of disclosure.
The defence'sc choice to have a preliminary inquiry before setting a matter for trial cannot be used as an excuse for delay of disclosure.
The most obvious reasons for withholding disclosure in where it is (1) "clearly irrelevant"; (2) the information was privileged; (3) disclosure of the information was governed by law; and (4) premature disclosure may result in harm to an individual or public interest.

When the Obligations Exist
The Crown will only be subject to disclosure obligation where there is evidence in its possession or control and it is relevant. This is will only apply once the defence seeks to exercise its right to disclosure.
Information in possession of the government but not discovered in the course of the investigation is not governed by Stinchcombe.  Stincombe will generally only apply to the "fruits of the investigation". 
R v Elkins, 2017 BCSC 245 at para 24
Elkins at para 25
Defence Engaging Disclosure Obligations
The right to disclosure is triggered once defence counsel requests it.
The obligation will exist for all evidence for which there is a "reasonable possibility" that the evidence will used in making full answer and defence.
The duty to disclose is engaged once the accused requests information from the crown any time after the charge has been laid.  If defence fails to raise the issue and remains passive, they are less able to claim that non-disclosure affected trial fairness.
Defence have an obligation to diligently pursue disclosure by actively seeking and pursuing disclosure once they become aware or ought to have been aware of it. This means the defence should bring any failure to disclose to the Court's attention at the earliest opportunity so that the judge can remedy any trial unfairness.
Defence cannot claim a lack of disclosure affected trial fairness when they remain passive a tactical decision or due to lack of diligence.
Defence should not engage in disclosure requests that amount to mere "fishing expeditions" as they tend to "undermine the good faith and candour which should govern the conduct of counsel."
R v Stinchcombe,  3 SCR 326, 1991 CanLII 45 (SCC), per Sopinka J., at p.342 ("The obligation to disclose will be triggered by a request by or on behalf of the accused. Such a request may be made at any time after the charge.")

Once the right to disclosure has been invoked by the Defence the onus is upon the Crown to comply with the obligation. The Crown may refuse to disclose certain information, but has the burden of proving why full disclosure should not be applied.
If the crown disputes the existence of any particular material, the applicant "must establish the basis that could enable to court to conclude that further material exists that is potentially relevant. The existence of the disputed material must be sufficiently identified, not only to reveal its nature but also to permit the court to conclude that it made meet the test required for prosecutorial disclosure".
The information will not be considered disclosure where it is: 
- Not in the control of the Crown
Satisfying any one of these requirements will eliminate any disclosure obligations upon the Crown. The Crown may then refuse the request.
The grounds to disclose must be established on a balance of probabilities.

Possession or Control
Just because a record is in the possession of a Crown entity, does not amount to possession or control.
The law cannot impose an obligation of the crown in relation to materials that "does not have or cannot obtain". 
Where evidence is not in the control of the Crown it may be the subject of a common law third party records application, also known as an "O'Connor Application".
In an O'Connor application the Defence must show that the evidence is "likely relevant".
The prosecuting Crown has an obligation to "make reasonable inquiries of other Crown entities and other third parties" of whether they may be in possession of relevant evidence.
Not all information in possession of police must be disclosed. It must only be "relevant" evidence. The "threshold question in any instance of non-disclosure is whether the evidence was relevant"
The threshold of relevancy is quite low. The relevancy exists where there is "a reasonable possibility of the information being useful to the accused in making full answer and defence". Full answer and defence is engaged where the evidence can be used:
- in meeting the Crown's case;
- "advancing a defence";
- "otherwise in making a decision which may affect the conduct of the defence such as, for example, whether to call evidence".
The scope of relevancy is "broad" and will include materials that "may have only marginal value to the ultimate issues at trial." The Crown "must err on the side of inclusion" when deciding whether to include the materials in disclosure.
Relevance is not limited solely to inculpatory evidence nor only evidence that the Crown would adduce at trial. "Relevant materials" includes all materials for which there is a "reasonable possibility" that it may be useful for the Defence. All possible exclupatory evidence must be provided as well, however, this obligation does not extend to a duty to examine the exculpatory evidence.
Relevance can be related to the usefulness for defence as far as decisions on conducting the defence including whether to call evidence.
Relevant evidence is not limited to admissible evidence and can include that evidence which is not inadmissible at trial.
Relevancy however can be limited by the need for a "realistic standard of disclosure consistent with fundamental fairness." It must still permit the sustem to be "workable, affordable and expeditious". It should not be so broad as to include "anything that might conceivably be used in cross-examination".
There is some authority to suggest that when the relevancy only relates to a voir dire on admissibility of evidence, and not the trial itself, the burden is upon the accused.
Refusal to disclose clearly irrelevant disclosure
The burden is upon the Crown to prove that the information was "clearly irrelevant".
Refusal to disclose is reviewable by the trial judge.

Privileged materials can take many forms:
- protection of persons from harassment or injury
- protect informer privilege 
- protect confidential investigative techniques 
- protection of confidential information while an investigation is ongoing 
- statutory privilege such as under the Code and CEA
Any materials in control of the Crown that is claimed to be privileged cannot be compelled to disclose to either the defence or the court unless there are proper grounds.  The McClure threshold test determines the grounds which requires the materials could raise a reasonable doubt of guilt. The threshold test requires:
- there be no other source of the information sought;
- the accused cannot raise a reasonable doubt in any other way.
Materials that "may put at risk the security and safety of persons who have provided prosecution with information" is protected by informer privilege.
Where the materials are privileged there is no need to address threshold relevance.
Where the defence seek disclosure of claimed privileged materials, "the accused has the burden of demonstrating why privilege is wrongly claimed".

Duration of the Obligation
The obligation to provide disclosure only begins once charges have been laid. There is no right prior to that.
The duty is engaged upon the request of the Defendant. It is continuous throughout the proceedings up to and including the trial. The Crown may object to the request on the basis that it is irrelevant, outside of their control, or otherwise privileged. The burden is on the Crown to justify the refusal to disclose.
The duty to disclose is ongoing and so any new information received must also be disclosed.
Once the Crown alleges that it has fulfilled the disclosure obligation it has no obligation to justify the "non disclosure of materials the existence of which it is unaware or denies." Unless the applicant is able to "establish a basis which could enable the presiding judge to conclude that there is in existence further material which is potentially relevant...".
The right to disclosure may not extend to the into a conditional sentence breach hearing as there is less of a right to full answer and defence.
The obligation to disclose remains in effect through the appellate process. This obligation covers any materials in the possession of the crown that "may reasonably assist the appellant in the prosecution of his or her appeal, subject to any privilege or overriding third-party privacy interest".
Where in applicant seeks further disclosure on appeal to support a fresh evidence application, he must establish that:
- There is a connection between "the request for production and the fresh evidence proposed, or in other words the applicant must show that there is a reasonable possibility that the material sought could assist on the application for fresh evidence"
- There is some reasonable possibility that the evidence to which the production request is linked may be received as fresh evidence on appeal.
Timing of Disclosure
- see also: Delayed Disclosure, above
Conceptually, Dislcosure can be divided into three phases:
- "Initial disclosure": evidence required before there can be an election of mode of trial;
- "Intermediate disclosure": evidence required before a plea is entered; and
- "Final dislcosure": all Dislcosure must be provided prior to trial.
It is not always necessary to provide full disclosure prior to a preliminary inquiry as long as full disclosure is made early enough before trial so as not to violate the right to full answer and defence. Where sufficient but incomplete evidence is disclosed, the defence are not entitled "to refuse to proceed to the next step or to set a date for trial".
Consequence of Late Disclosure
Where the late disclosure does not amount to a Charter breach that would require a stay of proceedings, the judge can consider a mistrial, a refusal to admit the evidence or an adjournment.
Witnesses Changing Evidence
Where the Crown learns of a recanting witness and provides immediate notice to the defence counsel on the night before the witness is to testify, it does not violate the right to full answer and defence.

Sufficiency of Existing Disclosure
It is not appropriate for the "Stinchcombe obligations" to be interpreted as creating any sort of duty investigate.
See Expert Evidence#Notice to Call Expert Evidence for details on sufficiency of disclosure summarizing the expert's evidence. A failure to provide sufficient disclosure in relation to the experts could result in a mistrial.
Duty to Inquire and Obtain Disclosure ("McNeil" Obligations)
In "appropriate cases", the Crown has an obligation "to make reasonable inquiries" with third-party states authorities who are believed to be in possession of relevant materials.
For the purpose of first-party disclosure obligations, the "Crown" refers to the "prosecuting Crown" only.
This may include the provincial securities commission who are known to have undertaken a investigation related to the prosecution. 
It is not a valid argument to simply assert that the inquiry should be made because it is "easy".

- R v Woods, 2015 ABPC 23 (CanLII), at para 31 ("it is important to remember that the accused does not overcome the hurdle of providing evidence that the information sought actually exists and is relevant by showing only that the inquiry is easy to make. If it were otherwise, “easy inquiries” would quickly become the equivalent of first party disclosure and the authorities would suffer death by a thousand cuts.")
Procedure For Enforcing Right
Where disclosure issues arise, the court should consider the issues as follows: 
- establish a violation of the right to disclosure;
- demonstrate on a balance of probabilities that the right to make full answer and defence was impaired as a result of the failure to disclose;
- discharge this burden by demonstrating that there is a reasonable possibility that the non-disclosure affected the outcome at trial or the overall fairness of the trial process.
A preliminary inquiry judge has no jurisdiction to order the crown to provide disclosure.
Only the trial judge may make an order directing the Crown to disclose information in its control. Accordingly, a provincial court judge cannot order disclosure unless the mode of trial was by provincial court judge.
A preliminary inquiry judge has no power to order disclosure and is not a "court of competent jurisdiction" to make such an order.
Where defence believe initial disclosure is insufficient for making election, the justice may adjourn the election to allow the accused to seek remedy from a superior court.
Where a superior court is the trial court, it will be a "court of competent jurisdiction" under s. 24(1) of the Charter.
A superior court should generally defer motions until the matter is before the trial court rather than still with the inferior court.
In "unusual" or "exceptional" cases a superior court justice may exercise jurisdiction under s. 24(1) of the Charter to order disclosure while the matter is still before a preliminary inquiry judge. The limited jurisdiction to order disclosure does not affect the Crown obligation to provide timely disclosure.
Issues relating to the "manner of disclosure tend to fall within the category of exceptional cases".

Crown Disclosure Decisions
Review of Decisions
It is the Crown's decision to determine "what material is properly subject to disclosure to the defence".
The decisions of Crown to disclosure certain information and not other is reviewable the trial judge.
In exceptional circumstances any superior court of criminal jurisdiction may review the disclosure under s. 24(1) of the Charter.
Remedy for improper disclosure decisions are "largely, but not exclusively, Charter based."

Types of Disclosure
Where the Obligation Does Not Exist
It is not appropriate for the "Stinchcombe obligations" to be interpreted as creating any sort of duty investigate or defend.
When documents are to be released for disclosure, the police and crown are permitted to vet the materials for the purpose of removing information that may not be disclosable. Types of information that can be validly redacted from the disclosure before going out to the defence include:
- clearly irrelevant information
- information tending to identify a confidential police source
- police investigative techniques
- advice that would be covered by solicitor-client privilege (either defence counsel or crown counsel)
See further details on Privilege section.
Restricting Access to Disclosure
Breach of Disclosure Obligation
To engage Stinchcomb the Applicant accused has the burden of proving that there was a "reasonable possibility" that his right to make full answer and defence was impaired by the Crown's actions.
Not every failure to comply with Stinchcombe obligations will result in a Charter breach. There will no Charter breach if the failure "could not possibly affect the reliability of the result reached or the overall fairness of the trial process."
Where relevancy is in dispute, the burden rests on the accused to prove on a balance of probabilities that breach of the Charter right to disclosure has been violated.
Where a breach of the right to full disclosure is found it does not necessarily follow that the right to make full answer and defence was violated. Where the right to make full answer and defence is not implicated, the usual remedy is either an adjournment or order of production. In fact in general, where disclosure has not been given or is given late, the usual remedy is an adjournment.
Where there is a failure on the part of the Crown to meet the Stinchcombe obligations, there is an obligation on the part of the defence to raise the issue.
A failure to disclose will invoke s. 7 and 11(d) of the Charter. A successful challenge to s. 7 or 11(d) of the Charter "will generally require a showing of actual prejudice to the accused's ability to make full answer and defence".
