Mischief is the Criminal Code's property damage offence. Section 430 makes it a crime to wilfully destroy or damage property, render it dangerous, useless, inoperative, or ineffective, or obstruct someone's lawful use or enjoyment of it. The charge shows up everywhere from broken phones during arguments to keyed cars, broken windows, and graffiti. Two things surprise people about it: you can be charged over property you partly own, and the word wilfully includes recklessness, not just deliberate destruction.

What is mischief under Canadian law?

The Crown must prove beyond a reasonable doubt:

One of the prohibited acts: destroying or damaging property; rendering it dangerous, useless, inoperative, or ineffective; or obstructing, interrupting, or interfering with the lawful use, enjoyment, or operation of property.
That the act was done wilfully: under section 429 of the Criminal Code, that means intentionally or recklessly, knowing the damage was likely and proceeding anyway. A true accident is not mischief.
Without legal justification, excuse, or colour of right: an honest belief in a legal right to deal with the property as you did is a defence.

Ownership is narrower than people assume. Because the offence protects other people's interests in property, a person can be charged with mischief for damaging jointly owned property, which is why the charge appears so often alongside domestic assault allegations: a phone or door damaged during a household argument belongs, at least in part, to someone else. The Criminal Code also contains separate mischief provisions for computer data and for property such as religious buildings and war memorials.

Penalties for mischief in Ontario

The penalties scale with value and danger. Mischief involving property worth more than $5,000 is a hybrid offence with a maximum of 10 years in prison by indictment; mischief involving $5,000 or less is hybrid with a maximum of 2 years by indictment or 2 years less a day on summary conviction. Where the mischief causes actual danger to life, the maximum is life imprisonment. There are no mandatory minimums.

Real-world outcomes for first-time, low-value allegations in Ontario are usually at the modest end: diversion, peace bonds, discharges, and probation, often with restitution as the centrepiece. Paying for the damage does not automatically end a prosecution, but it is frequently the practical key to a resolution that avoids a criminal record. Higher-value damage, repeated conduct, and hate-motivated mischief are treated much more seriously. Two 2026 changes bear noting: from July 15, 2026, interfering with essential infrastructure, copper theft being Parliament's example, is a statutory aggravating factor, and from July 18, 2026 the Combatting Hate Act adds new offences for intimidating or obstructing access to places of worship, schools, and community centres and strengthens how the Criminal Code addresses hate-motivated crime.

Possible defences to a mischief charge

Depending on the evidence, defences may include:

Colour of right: an honest belief in a legal right to deal with the property, common in disputes over shared belongings, tenancies, and property lines.
Accident: damage caused without intent or recklessness is not wilful and is not the offence.
Ownership and consent: sole ownership of the property, or the consent of the other interest-holder.
Identity: graffiti and vandalism prosecutions often turn on disputed identification, video quality, and attribution of tags.
Valuation: the over and under $5,000 line changes the charge, and repair estimates can be contested.
Charter issues, including statements taken without proper rights to counsel and unreasonable delay under section 11(b).

Frequently asked questions

Can I be charged with mischief for damaging my own property?

If the property is solely yours, generally no. But if it is jointly owned, for example with a spouse, or someone else has an interest in it, damaging it can be mischief. This is one of the most common ways the charge arises in domestic cases.

Is accidental damage mischief?

No. The Crown must prove the damage was caused intentionally or recklessly. A genuine accident is a defence, though recklessness, foreseeing the likely damage and proceeding anyway, is enough for the Crown.

If I pay for the damage, will the charge be dropped?

Not automatically, but restitution is often the practical path to diversion, a peace bond, or a withdrawal. The Crown, not the property owner, decides whether the prosecution continues.

What are the penalties for mischief?

Up to 2 years by indictment for property worth $5,000 or less, up to 10 years for property over $5,000, and up to life where the mischief endangers life. First-time, low-value matters usually resolve far below the maximums.

Is graffiti a criminal offence?

Yes, graffiti is prosecuted as mischief. Cases typically turn on identification and attribution, and municipal by-law or diversion resolutions are sometimes available for minor incidents.

What is mischief endangering life?

A separate, far more serious form of the offence where the wilful damage causes actual danger to life, such as tampering with equipment or infrastructure. It is punishable by up to life imprisonment.
