The Short Answer
Bail in Ontario — formally called judicial interim release — is governed by section 515 of the Criminal Code and is built on a presumption in favour of release. Courts must release an accused on the least restrictive conditions that address any real risk, and can only order detention where it is justified on one of three specific legal grounds. This guide walks through exactly how that process works.
What “Bail” Actually Means
When someone is charged with a criminal offence, they are either released by police at the scene or station (with or without conditions), or held for a bail hearing before a justice of the peace or judge. At that hearing, the court decides whether the accused will be released while the case proceeds, and if so, on what conditions. This process — not the trial itself — is what most people mean by “bail.”

The Three Grounds for Detention
A court cannot detain someone simply because they have been charged. Detention pending trial must be justified on at least one of three specific legal grounds:
| Ground | What It Addresses |
|---|---|
| Primary Ground | Ensuring the accused attends court as required |
| Secondary Ground | Protecting public safety — including the risk of further offences or interference with the justice process |
| Tertiary Ground | Maintaining public confidence in the administration of justice, considering the strength of the case, seriousness of the offence, and potential penalty |
The Ladder Principle: Least Restrictive Release
Ontario and Canadian bail law is built around the ladder principle: a court must start with the least restrictive form of release and only move to a more restrictive form if satisfied that a less onerous option would not adequately address the relevant grounds for detention.
The ladder principle means release on a simple undertaking, with no surety and no cash deposit, is the legal starting point — not a surety-backed recognizance. A court must justify climbing the ladder, not the other way around.
Forms of Release, From Least to Most Restrictive
| Form of Release | What It Involves |
|---|---|
| Undertaking | A signed promise to comply with conditions, with no financial pledge |
| Recognizance without sureties | A promise to pay a set amount if conditions are breached, without needing another person to supervise |
| Recognizance with sureties | One or more people agree to supervise the accused and pledge money that can be forfeited for a breach |
| Cash deposit | A sum of money deposited with the court, typically reserved for accused persons who do not ordinarily reside in the province |
| Detention | The accused is held in custody pending trial, only where release on any form of conditions cannot be justified |
What Is a Surety and What Do They Have to Do?
A surety is typically a family member or close friend who agrees to supervise the accused in the community and pledges a specific sum of money to the court. If the accused breaches a bail condition, the surety can be required to forfeit that amount.
Before being approved, a proposed surety generally must show the court:
- They understand the seriousness of the responsibility they are taking on
- They have a genuine ability to supervise the accused, including a reasonable living arrangement
- They have no disqualifying circumstances of their own (such as a serious, related criminal record)
- They have the financial means to satisfy the amount they are pledging, if called upon
A person's parent agrees to act as their surety, pledging $5,000 and agreeing to have the accused reside with them under a curfew. If the accused later breaches the curfew and it is reported to police, the surety can be brought before the court and, in some circumstances, required to forfeit some or all of the pledged amount.
Reverse Onus: When the Accused Must Justify Release
For most offences, the Crown bears the burden of showing why an accused should be detained. However, certain circumstances — including some offences allegedly committed while the accused was already on release for another indictable offence, along with other specific categories set out in the Criminal Code — trigger a reverse onus, meaning the accused must instead justify why they should be released.
A reverse onus does not mean release is impossible — the ladder principle still applies once the onus is met — but it does mean the accused carries the burden of persuading the court, making strong preparation and legal representation especially important.
Common Bail Conditions
Conditions are tailored to the specific risks in each case, but commonly include:
- Residence conditions — living at a specific, approved address
- No-contact orders — prohibiting contact with alleged victims or witnesses
- Area restrictions — avoiding specific locations, such as the alleged victim's workplace or neighbourhood
- Curfews — requiring the accused to be at their residence during specified hours
- Reporting conditions — checking in with a bail supervisor or police on a set schedule
- Weapons prohibitions — surrendering any weapons and firearms licences
- Substance conditions — abstaining from alcohol or drugs, particularly where relevant to the alleged offence
What Happens If You Breach a Bail Condition?
Breaching a bail condition — even one that seems minor, like missing a curfew by a short window — is itself a separate criminal offence: failure to comply with a release order. It can result in re-arrest, an additional charge, and a much more difficult path to release on the original matter, since a breach undermines the court's confidence that the accused will respect further conditions.
See our dedicated page on failure to comply with bail conditions for what a breach charge involves and how to respond.
How Long Does a Bail Hearing Take?
A straightforward bail hearing, especially where the Crown consents to release on agreed conditions, can sometimes be resolved within a day or two of arrest. Contested bail hearings — particularly those involving a reverse onus, multiple proposed sureties, or complex proposed conditions — take longer to prepare and argue, and may require an adjournment to properly assemble sureties and evidence.
Can Bail Be Denied Entirely?
Yes, if the court is satisfied that no form of release — even with the most restrictive conditions — adequately addresses the primary, secondary, or tertiary grounds for detention. Detention is meant to be a measure of last resort, not a default outcome, but it can and does occur, particularly for very serious charges, cases involving a reverse onus, or an accused with a history of failing to comply with prior release conditions.
Can You Change Bail Conditions Later?
Yes. If circumstances change — for example, a surety is no longer available, or a residence condition becomes impractical — either the accused or the Crown can apply to vary the existing conditions. This can often be resolved by consent between the Crown and defence where the change is reasonable, or through a formal variation hearing if it is contested. If bail is denied entirely, the accused can also seek a bail review before a higher court.
Common Myths About Bail
Myth: “You need cash to get bail in Ontario.”
False for most accused persons. A cash deposit is generally reserved for accused persons who do not ordinarily reside in the province. Most Ontario residents are released on an undertaking or a recognizance, which does not require an upfront cash payment.
Myth: “A surety has to be a lawyer or professional.”
False. A surety is typically a family member, friend, or other person the accused has a genuine relationship with — what matters is their ability to supervise the accused and their understanding of the responsibility.
Myth: “If you're charged with a serious offence, bail is automatically denied.”
False. Even serious charges — including those carrying a reverse onus — can result in release, provided the accused can propose conditions, and often a surety, that adequately address the court's concerns.

Frequently Asked Questions
Bail, formally called judicial interim release, is the process by which a person charged with a criminal offence is released from custody while their case is ongoing, generally subject to conditions. It is governed by section 515 of the Criminal Code and is based on the presumption that an accused person should not be detained unless the Crown (or, in certain cases, the accused) cannot justify release.
Not automatically, but there is a strong presumption in favour of release for most offences. The Crown generally has the burden of showing why detention is justified, though certain serious or repeat offences trigger a "reverse onus," shifting that burden to the accused. A court can only order detention if it is justified on one of three specific legal grounds.
The ladder principle, codified in the Criminal Code, requires a court to release an accused on the least restrictive form of release that is justified by the circumstances — starting with release on a simple undertaking and only moving to more restrictive forms, like a recognizance with sureties, if a less restrictive option is not sufficient.
A surety is a person — often a family member or close friend — who agrees to supervise the accused while they are on release and to pledge a sum of money that can be forfeited to the court if the accused breaches their conditions. Before being approved, a surety must satisfy the court they understand the responsibility, have some ability to supervise the accused, and have no disqualifying circumstances themselves.
For certain serious charges — including some offences committed while already on release for another indictable offence, and other specific categories set out in the Criminal Code — the accused must justify why they should be released, rather than the Crown having to justify detention. Reverse onus hearings are generally harder to win release at, though the ladder principle still applies once the onus is met.
A court can only detain someone pending trial if detention is necessary: (1) to ensure the accused attends court (the primary ground), (2) to protect public safety, including concern the accused will commit further offences or interfere with the justice process (the secondary ground), or (3) to maintain public confidence in the administration of justice, considering factors like the strength of the case and seriousness of the offence (the tertiary ground).
Common conditions include reporting to a bail supervisor or police, residing at a specific address, remaining within a certain area, no-contact orders with alleged victims or witnesses, curfews, weapons prohibitions, and abstaining from alcohol or drugs. Conditions are tailored to the specific risks in each case and should not be more restrictive than necessary.
Breaching a bail condition is itself a separate criminal offence — failure to comply with a release order — and can result in re-arrest, additional charges, and a much more difficult path to release going forward, since a breach undermines the court's confidence that further conditions will be respected. See our guide on failure to comply with bail conditions for a full breakdown.
A straightforward bail hearing can sometimes be resolved the same day or within a day or two of arrest, particularly if the Crown consents to release on agreed conditions. More contested bail hearings, especially those involving a reverse onus or complex sureties, can take longer to schedule and argue.
Yes. If an accused is detained, they can apply for a bail review before a higher court, which can reconsider the detention decision, particularly if there has been a material change in circumstances or an error in the original decision.
Yes. Either the accused or the Crown can apply to vary bail conditions if circumstances change — for example, if a residence condition becomes impractical, or if the Crown believes new information justifies stricter conditions. This is generally done by consent where possible, or through a formal variation application.
Strongly recommended. A bail hearing happens quickly, often within hours or days of arrest, and the outcome can significantly affect the rest of the case. A lawyer can help identify an appropriate surety, propose realistic conditions, and argue effectively for the least restrictive form of release the circumstances allow.
