Mass Tsang LLP provides defence for a focused range of criminal charges in Toronto, including sexual assault, domestic assault, general assault, impaired driving (DUI), drug trafficking and possession, theft and fraud, and traffic ticket offences. Our lawyers also assist clients with bailhearings and release planning. Because our criminal lawyers practise solely in criminal law,clients receive highly specialized representation built on decades of courtroom experience.
You should contact a criminal lawyer as soon as possible—ideally before speaking to the police. If you have been arrested, charged, or believe you are under investigation, early legal advice is critical. The sooner your lawyer can review the facts, the more time there is to preserve evidence, prepare a defence strategy, and potentially prevent charges from being laid. Waiting until a court date is set can limit your lawyer’s ability to achieve the best outcome.
Mass Tsang provides transparent, flat-rate fees with no hidden costs. The total fee depends on the nature and complexity of your charges, whether the matter proceeds to trial, and other case-specific factors. During your free consultation, we will provide a clear breakdown of costs so there are no surprises.
During your first meeting at Mass Tsang, a lawyer will listen to your account of events, review any documents or disclosure you have received, explain the applicable laws and potential penalties, and discuss preliminary defence strategies. The consultation is confidential and non-judgmental. Our goal is to give you a clear understanding of where you stand legally and what steps come next.
Absolutely. Impaired driving defence is one of our core practice areas. Toronto’s mandatory penalties for DUI offences can include licence suspension, heavy fines, and even jail time. Our DUI lawyers have extensive experience challenging breathalyzer evidence, roadside testing procedures, and Charter rights violations. We have a proven track record of having impaired driving charges reduced or dismissed entirely.
Sexual assault cases often hinge on the credibility of the evidence and the complainant’s testimony. Our lawyers conduct a thorough review of all disclosure, cross-examine witnesses, and identify inconsistencies or procedural errors that can be used in your defence. Given the severity of the consequences—which can include imprisonment and registration on the National Sex Offender Registry—having experienced criminal lawyers on your side from the outset is essential.
Yes. Our theft and fraud lawyers are devoted to defending clients facing allegations ranging from shoplifting and theft under $5,000 to complex fraud cases involving large sums. Being labelled a thief can have devastating consequences for your career and reputation. We work to limit your exposure to the court system and fight to keep your record clean through charge withdrawals, reduced charges, or alternative resolutions.
Yes. In addition to criminal defence, Mass Tsang offers family law services covering divorce, child custody disputes, and spousal and child support matters. Our family lawyers understand that these issues are often deeply personal and emotionally difficult, and we provide practical, compassionate legal advice to help you navigate even the most challenging family situations.
Mass Tsang LLP is based in Toronto at 5075 Yonge Street, Suite 501, and serves clients throughout the Greater Toronto Area, including North York, Mississauga, Brampton, Vaughan, Richmond Hill, Newmarket, Oshawa, Milton, Barrie, Kitchener, Guelph, and Burlington. Our lawyers regularly appear in courthouses across the GTA and are familiar with the local prosecutors and judges in each jurisdiction.
No ethical lawyer can guarantee a specific outcome in a criminal case, as every case depends on its own unique facts and circumstances. However, our track record of over 1,000 complete dismissals demonstrates our ability to consistently achieve favourable results. We will always give you an honest assessment of your case and work tirelessly to pursue the best possible outcome, whether that means a complete dismissal, a reduction in charges, or an acquittal at trial.
The Ontario criminal justice system is complex, and even a seemingly minor charge can result in a criminal record, jail time, fines, and long-term consequences for your employment, immigration status, and ability to travel. A criminal lawyer understands case law, courtroom procedure, and the strategies prosecutors use. At Mass Tsang, our team has secured over 1,000 complete dismissals of charges. Self-representation puts you at a significant disadvantage when the Crown has experienced prosecutors working against you.
Yes. Mass Tsang offers a free initial consultation where you can discuss the details of your case with one of our experienced criminal lawyers. During this meeting, we will review the charges, explain the legal process, outline potential defence strategies, and answer your questions.
If you are arrested, exercise your right to remain silent and ask to speak with a lawyer immediately. Do not provide a statement to the police before receiving legal advice. After your release, contact Mass Tsang as soon as possible to schedule a consultation. Bring any documents the police gave you, including your release conditions, court dates, and any paperwork related to breath tests or other procedures. Early legal intervention is the most important step you can take to protect your future.
Penalties for a criminal conviction in Ontario vary depending on the offence and can include fines, probation, community service, house arrest, and imprisonment. Beyond the sentence itself, a criminal record can affect your employment prospects, professional licensing, immigration status, ability to travel internationally (including entry to the United States), and your personal reputation. This is why mounting an effective defence is so important, and why our lawyers work aggressively to have charges dismissed, withdrawn, or reduced whenever possible.
Domestic assault charges are taken very seriously by Ontario courts, even when the incident involved minimal physical contact. Once charges are laid, the Crown will typically proceed with prosecution even if the complainant wants to drop the case. You may face assault, assault causing bodily harm, or aggravated assault charges. Our domestic assault lawyers will review the evidence, identify weaknesses in the prosecution’s case, and work toward the best possible outcome—whether that is a withdrawal of charges, acquittal, or a reduced charge that keeps your record clean.
Our drug lawyers defend clients facing a wide range of drug-related charges, including simple possession, possession for the purpose of trafficking, drug trafficking, and production. Whether the charges involve cannabis, cocaine, opioids, or other controlled substances, we develop defence strategies that challenge the legality of searches, the handling of evidence, and the strength of the Crown’s case. From bail to trial, we work closely with our clients at every stage.
Yes. If you or a loved one has been arrested and detained, securing bail is an immediate priority. Our criminal lawyers are experienced in preparing bail plans, presenting sureties, and arguing for release on the most favourable terms. We understand the urgency of bail hearings and are available on short notice, including evenings and weekends, to ensure you are not held in custody any longer than necessary.
Yes. Mass Tsang provides immigration law services to clients in Toronto and the GTA. A criminal charge or conviction can have serious implications for your immigration status, including the risk of deportation or inadmissibility. Our lawyers understand how criminal and immigration law intersect and can advise you on protecting your status while defending against criminal charges.
Several things set us apart. Our lawyers practise solely in criminal law, which means every member of the team brings focused, specialized expertise to your case. With over 30 years of combined experience and more than 1,000 complete dismissals, we have a deep understanding of how to achieve results. Unlike firms where you may be passed between lawyers, at Mass Tsang you benefit from the collective knowledge of our entire team of criminal lawyers. We also offer transparent flat-rate fees, free initial consultations, and flexible scheduling including evenings and weekends.
No. You have the constitutional right to remain silent and to speak with a lawyer before answering any questions from the police. Anything you say can and will be used against you. Even if you believe you are innocent and have nothing to hide, seemingly harmless statements can be taken out of context and damage your defence. Contact Mass Tsang first, and our lawyers will advise you on how to proceed.
