Understanding Criminal Charges in Ontario

If you or someone you know is facing criminal charges in Toronto or the Greater Toronto Area, understanding the type of charge and its potential consequences is the first step toward protecting your rights and your future.

Criminal offences in Canada are classified into three categories: summary conviction offences (the least serious, carrying a maximum penalty of two years less a day), indictable offences (the most serious, with penalties up to and including life imprisonment), and hybrid offences (which the Crown can prosecute as either summary or indictable depending on the circumstances). The specific charge you face determines which court will hear your case, whether you may elect a jury trial, and the range of penalties upon conviction.

The criminal defence lawyers at Mass Tsang have over 30 years of experience defending clients across the full spectrum of criminal charges in Toronto and the GTA. Below is an overview of the practice areas we cover. Select any area to learn more about the specific charges, penalties, and defence strategies involved.

Practice Areas

Driving Offences

Driving under the influence of alcohol or drugs is one of the most commonly charged criminal offences in Ontario. Penalties upon conviction include licence suspension, heavy fines, a criminal record, and potential jail time—even for a first offence. Mass Tsang’s DUI lawyers have extensive experience challenging breathalyzer evidence, roadside testing procedures, and Charter rights violations to get charges reduced or dismissed.

Drug Offences

Drug offences in Canada are governed by the Controlled Drugs and Substances Act (CDSA) and include simple possession, possession for the purpose of trafficking, trafficking, production, and import/export. Penalties range from fines for minor possession to life imprisonment for serious trafficking offences involving Schedule I substances such as cocaine, fentanyl, and heroin. Our drug lawyers challenge police procedures, search warrants, and evidence handling to build effective defences.

Violent Offences

Assault charges in Ontario range from simple assault (unwanted physical contact or threats) to aggravated assault (causing serious bodily harm). These are hybrid offences, meaning the Crown can proceed summarily or by indictment depending on severity. Penalties can include significant jail time and a permanent criminal record. Defence strategies often focus on self-defence claims, consent, and challenging the credibility of the complainant.


Domestic assault involves allegations of physical or threatening behaviour against a current or former intimate partner, family member, or household member. These charges carry additional consequences including restrictive bail conditions that may force you out of your home. The Crown treats domestic cases with heightened severity, and a conviction can affect custody arrangements and immigration status. Our lawyers understand the sensitive dynamics of these cases.

Sexual Offences

Sexual assault is one of the most serious criminal charges a person can face in Canada. Convictions carry lengthy prison sentences and mandatory registration on the National Sex Offender Registry, which has lifelong consequences for employment, travel, and reputation. These cases often hinge on credibility, consent, and the strength of the physical evidence. Our lawyers conduct rigorous reviews of all disclosure to identify inconsistencies and procedural errors in the Crown’s case.

Property Crimes

Theft and fraud offences cover a broad range of conduct, from shoplifting and identity theft to large-scale financial fraud. The Criminal Code distinguishes between offences involving values under and over $5,000, with significantly harsher penalties for the higher threshold. A conviction can devastate professional licences, security clearances, and future employment. Defence strategies often involve challenging the evidence of intent and the valuation of the alleged loss.

Regulatory Offences

While traffic tickets are not criminal offences, serious driving violations—such as careless driving, stunt driving, and driving with a suspended licence—carry substantial fines, demerit points, licence suspensions, and insurance consequences. Some traffic violations can also overlap with criminal charges under the Criminal Code. Our lawyers represent clients in traffic courts across the GTA to minimize penalties and protect driving records.

Court Process Services

If you or a loved one has been arrested and held in custody, a bail hearing is the first critical step in the criminal process. The outcome determines whether you remain in jail or are released while awaiting trial—and under what conditions. Our bail hearing lawyers are available 24/7 and regularly appear on short notice to argue for release on the least restrictive terms possible.

Additional Legal Services

In addition to criminal defence, Mass Tsang offers family law services covering divorce, child custody disputes, and spousal and child support matters. Family law issues frequently intersect with criminal charges—particularly in cases involving domestic assault, where bail conditions and custody arrangements may overlap. Having one firm handle both sides ensures coordinated legal strategy.


Criminal charges and convictions can have devastating immigration consequences for non-citizens in Canada, including deportation, inadmissibility for permanent residence, and denial of citizenship applications. Our immigration law team works alongside our criminal defence lawyers to ensure that the immigration implications of any charge are considered from the outset.

Frequently Asked Questions About Criminal Charges in Toronto

Canadian criminal law categorizes offences into three types based on severity. Summary conviction offences are the least serious, carrying a maximum penalty of two years less a day in jail. Indictable offences are the most serious, with penalties that can include life imprisonment. Hybrid offences (also called dual procedure offences) can be prosecuted as either summary or indictable, with the Crown choosing based on the circumstances of the case. The classification affects which court hears the case, whether you can elect a jury trial, and the range of penalties upon conviction.

Contact an experienced criminal defence lawyer as soon as possible—ideally before making any statement to police. You have the right to remain silent and the right to speak with a lawyer under the Canadian Charter of Rights and Freedoms. Do not discuss the details of your case with anyone other than your lawyer. Attend all scheduled court appearances and comply with any bail conditions imposed upon your release. The earlier a lawyer is involved, the more options are available to challenge the charges.

A criminal charge does not automatically result in a criminal record—only a conviction does. If the charges are withdrawn, stayed, or you are found not guilty at trial, you will not have a criminal record for that offence. In some cases, a discharge (absolute or conditional) may be available even if you plead guilty, which means no criminal record is entered. An experienced lawyer can advise you on the likelihood of a non-conviction outcome in your case and work toward the best possible resolution.

Summary offences are less serious charges tried in the Ontario Court of Justice, with a maximum penalty of two years less a day in jail and limited fines. You do not have the right to a jury trial or a preliminary hearing for summary offences. Indictable offences are far more serious, tried in either the Ontario Court of Justice or the Superior Court of Justice depending on the specific charge. Indictable offences carry much harsher maximum penalties—up to and including life imprisonment—and may entitle you to elect a jury trial and a preliminary hearing.

Yes. It is common for individuals to face multiple charges arising from the same incident. For example, a single encounter could result in charges for both assault and uttering threats, or drug possession and possession for the purpose of trafficking. Each charge must be proven independently by the Crown, and an experienced defence lawyer will address the evidence for each charge separately to build the strongest possible overall defence.
