How a case moves here
Ontario follows Oregon law on arrests, release, and courts; the full set covers prosecutors, defense, and jails too.
- Who decides release first
Before arraignment, the jail releases people under a standing order written by the presiding judge of each judicial district, or a release assistance officer appointed by that judge decides. At arraignment, a judge makes the release decision. The standing order sets recognizance and conditional release, not dollar amounts.
ORS 135.233, 135.235, 135.240, 135.245Oregon Chief Justice Order 24-014, Release Guidelines (May 22, 2024)- Time to see a judge
A person held in custody must be arraigned within the first 36 hours of custody, not counting weekends and holidays, unless there is good cause or the defendant asks for more time.
ORS 135.010- Money bail
Senate Bill 48, in effect since July 1, 2022, ended security (money bail) schedules that applied right after arrest. A judge may still require security at arraignment after finding that release on recognizance or conditions is unwarranted.

Offenses Ontario Police Department reported to the FBI in incident detail (NIBRS), each year, the second table by the arrest class each offense falls in. Per 100k: offenses per 100,000 people the department polices, 2021 to 2023 added together, full years only, beside Oregon's rate over the same years. – means too few for a rate: the count is under 20.
* 2024: reported for part of the year only, so the count is short and the year is left out of the rate.
