If you need a witness to physically bring essential documents, financial ledgers, or digital records to a Canadian federal criminal trial, your lawyer must serve them with a Subpoena Duces Tecum (a subpoena “to bring with you”). Under the Criminal Code of Canada, this legally compels the person to appear in court and hand over the specific evidence, under threat of arrest for contempt.
Preparing a strong defence in a Canadian criminal trial often requires more than just verbal testimony. Sometimes, the evidence that can prove your innocence is locked away in a corporate office, a hospital file room, or a reluctant witness’s personal laptop. When a person or business refuses to hand over these crucial records voluntarily, the Canadian justice system provides a powerful mechanism to force their cooperation.
A standard subpoena only forces a person to show up and speak. A Subpoena Duces Tecum specifically commands them to bring physical or digital items with them to the courthouse. Whether you are defending against a complex financial fraud charge in Montreal or an assault allegation in Winnipeg, understanding how to legally compel the production of records is a cornerstone of modern criminal defence strategy.
Step-by-Step Process in Canada: Issuing the Subpoena
You cannot simply print a form off the internet and demand someone’s private records. The process is strictly governed by the federal Criminal Code of Canada and requires judicial oversight to protect people’s privacy rights.
Step 1: Identifying the Required Documents
🔍 Your defence lawyer will first determine exactly what documents are needed to prove your case. The request must be highly specific-you cannot go on a “fishing expedition.” For example, demanding “all emails between John and Jane for five years” will likely be rejected by a judge. Demanding “the accounting ledger for May 2026” is specific and legally sound.
Step 2: Drafting the Subpoena Duces Tecum
Your law firm will draft the formal subpoena document. This document will clearly state the name of the witness, the exact courthouse they must attend, the date and time of the trial, and a highly detailed schedule listing every single document, record, or physical item they are legally required to bring with them.
Step 3: Obtaining Judicial Approval
To make the subpoena legally binding, it must be signed by a judge, a justice of the peace, or the clerk of the court where your trial is being held. If the documents belong to a third party not involved in the crime (like a bank or a hospital), the judge will carefully review the request to ensure it does not unfairly violate privacy laws before signing it.
Step 4: Personal Service and Conduct Money
Unlike regular mail, a Subpoena Duces Tecum must generally be served personally to the witness. Depending on the situation, your lawyer may provide “conduct money.” 💰 Under Section 701 of the Criminal Code of Canada, providing conduct money is only a mandatory requirement for a subpoena to be legally valid if the witness is being summoned from out of province. For witnesses residing in the same province where the trial is held, there is no strict federal statutory requirement to pay conduct money upfront for the subpoena to be binding.
Step 5: The Witness Appears in Court
On the day of the trial, the witness must appear with the requested items. They will take the stand, swear an oath, and formally produce the documents. Your lawyer can then enter these documents into evidence as exhibits to support your defence.
How Much Does it Cost in Canada?
Compelling evidence through the court system involves specific administrative and legal expenses. As of May 2026, standard costs in CAD include:
- Process Server Fees: Hiring a professional process server to track down the witness and hand them the subpoena usually costs $100 to $350 CAD.
- Conduct Money (Out-of-Province): If summoning an out-of-province witness, you must pay their travel fare (mileage or transit) and a daily meal allowance (typically $20 to $75 CAD per day). This is not strictly required upfront for in-province witnesses under the Criminal Code.
- Lawyer Fees: Having a criminal defence firm draft, argue, and execute the subpoena can add $1,500 to $3,500 CAD to your overall legal bill.
How Long Does the Process Take?
Preparation is key. ⏱ A subpoena should be drafted and served at least 2 to 4 weeks before the trial date. If you serve a corporation just days before a trial demanding massive amounts of records, they will likely ask the judge to “quash” (cancel) the subpoena because they were not given adequate time to search their archives.

| Judicial Scrutiny | Routinely granted by court clerks. | Higher scrutiny to prevent privacy violations. |
Frequently Asked Questions (FAQ)
What happens if the witness ignores the Subpoena Duces Tecum?
Ignoring a valid, court-ordered subpoena is a massive legal mistake. If the witness fails to show up with the documents, the judge can issue a material witness warrant for their immediate arrest. They can be brought to court in handcuffs and charged with contempt of court.
Can a business refuse to hand over the documents?
A business cannot simply ignore it, but they can hire their own lawyer to file a motion to “quash” the subpoena. They might argue that the documents are protected by solicitor-client privilege, that the request is overly broad, or that producing them would be an unreasonable burden.
Does this work for getting medical or psychiatric records?
Yes, but there is an extra legal hurdle. In Canada, medical records involve deep privacy rights. To get a victim’s medical or therapy records in a criminal trial (often seen in sexual assault cases), your lawyer must follow the strict “O’Connor application” process before the subpoena is approved.
Who pays for the costs of photocopying thousands of pages?
Generally, the party issuing the subpoena is expected to cover reasonable expenses. If a corporation has to spend significant money compiling and copying digital archives, the judge may order your defence team to reimburse the company for those specific administrative costs.
