What disclosure typically includes
- Officer’s notes — the contemporaneous handwritten or digital notes from the issuing officer, including their observations and what they say the driver said.
- Device records — for radar or laser tickets, the make, model, serial number, and operator certification of the device used.
- Calibration logs — records showing the device was tested and functioning correctly within the required window.
- Photo radar materials — for ATE / photo radar tickets, the violation images, the operator data, and the deployment records for the location and time.
- Video — dashcam, body-worn camera, or intersection camera footage where applicable.
Why it matters
Defending a traffic charge without disclosure is defending blind. Most cases turn on whether the Crown can prove every element of the offence — and the documentation in disclosure is what shows whether that proof is actually available. A missing calibration record, an officer’s note that says something different from the ticket, or a photo radar deployment that fell outside the authorized parameters are all reasons a file looks defensible.
How to request it
Disclosure is typically requested in writing once the not-guilty plea is entered and the matter is set down for trial. The request goes to the Crown prosecutor’s office handling the matter and identifies the file by court file number, name, and date. Some courts have a standard form; others accept a letter.

Questions about traffic ticket disclosure
What is disclosure in a traffic case?
Disclosure is the evidence package the Crown intends to rely on at trial. For a traffic file, it typically includes the officer’s notes, any radar or laser device records, calibration logs, photo radar images and operator data, video where available, and similar materials.
When should disclosure be requested?
Disclosure is typically requested at or shortly after first appearance, once the not-guilty plea has been entered and the court file is open. Earlier requests may be premature; later requests can delay the trial.
What happens if disclosure is incomplete?
If material disclosure is missing or arrives late, the defence can raise that with the court. Remedies range from adjournments to, in some cases, more significant consequences for the Crown’s case. The right remedy depends on the specifics.
Does the driver pay for disclosure?
Standard disclosure is provided as part of the prosecution process; specialty items (full video, certain electronic records) sometimes carry administrative fees depending on the court and the agency. Costs are typically modest relative to the stakes of the file.
