If you have been charged with a criminal offence, you have the right to receive your “disclosure.” Requesting the disclosure from the Crown Prosecutor’s office is one of the first things your lawyer will do, and if you are representing yourself, it is one of the first things you should do as well.  Receiving and reviewing your disclosure occurs before you decide whether to enter a plea of guilty or not guilty. This allows you to understand the case against you and make an informed decision about whether to negotiate a deal or go to trial.

In criminal law, “disclosure” technically refers to the process and rules governing the exchange of information between the parties to prepare for legal proceedings. However, the word “disclosure,” as it is typically referred to in Court, refers to the “disclosure package” or “police investigation file” which is provided by the Crown to the accused person or their lawyer. The package usually includes the charge, police notes, witness statements, and other information gathered by the police during their investigation, such as photographs, recordings, and weapons.

To obtain a disclosure package, a request must be made to the Crown’s office. If you have been charged with a drug offence or other offences under federal jurisdiction, you will need to contact the office of the Federal Crown Prosecutor. Otherwise, most criminal charges under the Criminal Code of Canada come under the purview of the Provincial Crown Prosecutor’s office (i.e. Alberta Justice).

If you retain a lawyer, they will obtain disclosure for you. There are advantages of receiving disclosure at the early stages of your case, so approaching a lawyer to assist as soon as possible is recommended even before your first appearance in court.

The Crown has a legal obligation to disclose all relevant information to an accused person. In R v Stinchcombe, the Supreme Court of Canada ruled that accused individuals have the constitutional right to full and complete disclosure of the Crown’s case. Disclosure is important because it provides details about the case that accused persons must answer to and defend against.

There are various types of “disclosure,” including what is called “first-party disclosure, “third-party disclosure, " and defence disclosure. An experienced and knowledgeable lawyer will know what type of disclosure will be required in your case. In all criminal cases, “first-party disclosure,” otherwise known as the “fruits of the investigation,” is required to be provided by the Crown. This is what is usually referred to as “disclosure” as described earlier.

Generally, an accused does not have an equivalent obligation to disclose information like the Crown Prosecutor, but there are instances where the accused will be required by law to disclose information to the Crown and to the Court. In other cases, information held by a third party might be needed. To obtain third-party disclosure, a separate application may be required. It is recommended that you consult a lawyer who has the expertise to properly deal with such matters, as they can be lengthy and complex, and the sooner it is determined that disclosure applications need to be made, the better your lawyer will be able to defend you.

Obtaining timely disclosure of all relevant materials, particularly in the early stages of a case, has advantages including early resolution. Once disclosure is obtained, it is very important that accused people know and fully understand the details and nuances contained in a disclosure package. A skilled lawyer will be able to provide more information and the best available options after carefully reviewing the disclosure when deciding how to move forward with a case. If there are issues regarding non-disclosure and delays due to insufficient disclosure, certain remedies, such as a stay of proceedings, may also be available.

Therefore, if you have been charged with an offence, you are strongly encouraged to seek the assistance of an experienced lawyer who understands the challenges and difficulties of dealing with the criminal justice system, including issues with disclosure.
