Ontario Jury Summons Explained
Decode your letter, meet your deadlines, respond with confidence.
Skip to Reply StepsReceiving a jury summons can spark equal parts pride and panic. Sent by your local sheriff on behalf of the Superior Court of Justice, the document is a binding court order—not a polite invitation. Understanding every abbreviation and barcode on page 1 ensures you respond on time, avoid penalties up to $5 000, and make informed choices about deferral or excusal. This guide walks you line-by-line through the Ontario jury summons, clarifies key dates, and shows how to reply online in under ten minutes.
Key Parts of the Summons

1Court & File Number
The top-left corner lists the courthouse location code (e.g., “361 Uni” for Toronto) and a file reference such as “CR-24-00123”. “CR” signals a criminal panel, while “CI” marks a civil panel. Quote this number when phoning the Jury Office.
2Reporting Location & Date
Centred in bold font, this line shows where and when you may need to appear—often a Monday at 8:30 a.m. The date can shift after you complete the questionnaire, so keep an eye on follow-up letters.
3Juror Reference Number / Barcode
The eight-digit reference beside the barcode unlocks the online portal. Photograph it in case the paper copy goes missing; the court will ask for it whenever you call.
4Eligibility Questionnaire
Page 2 lists statutory questions—citizenship, age, criminal record—that decide whether you remain on the panel. Answer honestly; false statements fall under Criminal Code s. 131.
5Response Options
Three boxes let you choose: Confirm Availability, Request Deferral, or Apply for Excusal. Most jurors confirm online; those without internet can post the reply card or call the IVR line.

Deadlines & Penalties
Ontario courts use what clerks call the “5–14–Service Day Rule.” Memorise it and you will rarely stray into penalty territory:
Day Received | Within 5 Days | ≥14 Days Before Report Date | Day of Service |
---|---|---|---|
Note delivery date in calendar. This starts the clock—even if Canada Post stamps a later date. | Complete questionnaire online or mail reply card. Request any accessibility accommodation. | Submit deferral or excusal evidence (doctor’s note, travel proof) so the judge has time to review. | Appear at courthouse lounge by 8:30 a.m. or phone Jury Office if illness emerges overnight. |
How to Reply Online
- Locate the portal URL: It appears beside the barcode—usually ontario.ca/jury.
- Enter your Juror Reference Number: Eight digits, no spaces. Found top-right on the letter.
- Create a one-time passcode: The portal texts a six-digit PIN to verify identity.
- Confirm personal details: Update phone, email, and emergency contact so the court can reach you quickly.
- Answer eligibility questions: Citizenship, residency, criminal history, language proficiency.
- Select your reply: Confirm availability, request deferral, or apply for excusal. Upload evidence where prompted.
- Save your confirmation number: A five-character code appears on screen—screenshot or write it down.

Common Mistakes to Avoid
- Forgetting to confirm your submission—always record the portal confirmation code.
- Mailing the reply card without tracking—use Xpresspost or reply online to prevent “lost mail” issues.
- Uploading medical letters without your Juror Reference Number—clerks cannot match anonymous files.
- Assuming work travel is a valid excuse—file a deferral request instead of ignoring the letter.
- Relying on verbal promises—always follow-up phone calls with an email to the Jury Office.
- Missing the five-day questionnaire deadline—late submissions still need the form and an explanation letter.
- Using a nickname—portal and ID must match exactly; update Elections Ontario if needed.
- Bringing prohibited items (pepper spray, multi-tools) on report day—security delays can mark you absent.
