Practice Areas We Defend

If you are searching for a criminal defence lawyer in Mississauga, we provide rigorous advocacy across high‑stakes charges. Each case receives focused analysis, evidence control, and a credible defence plan.

  • Assault & Domestic Assault
    From simple assault to aggravated assault and uttering threats. We analyze credibility, self‑defence, identification, and context. The goal: expose gaps and secure outcomes that protect your future. 
  • Sexual Assault & Related Offences
    Intensive disclosure review, targeted motions, and careful witness management. We examine digital records, timing, and reliability, then prepare precise cross‑examination. 
  • Impaired Driving (DUI)
    Demand timing, instrument records, grounds for arrest, and Charter compliance are scrutinized. Strong procedure can be challenged; unlawful steps can justify exclusion of evidence. 
  • Drug Offences (possession, trafficking, production)
    Search warrants and grounds are tested line‑by‑line. We pursue full disclosure, contest unlawful searches, and challenge continuity where the record allows. 
  • Homicide: Murder & Manslaughter
    Complex trials require experienced strategy, expert management, and sustained preparation. We handle intricate evidentiary issues and—where applicable—jury dynamics with precision. 
  • Firearm & Weapons Offences
    Knowledge, control, and possession are contested alongside the legality of stops, searches, and warrants. Sentencing exposure is significant; intelligent litigation matters.

 

  • Fraud & White‑Collar Crime
    We dissect records, intent, and communications. Expect organized document review and, when helpful, expert input to counter overreach. 
  • Conspiracy & Criminal Organization
    Wiretaps, surveillance, and informant files demand careful disclosure litigation. We challenge shortcuts and guard Charter rights.
  • Criminal Harassment & Uttering Threats
    Context is often decisive. We assess credibility, communication history, and objective proof to build a credible defence path. 
  • Criminal Appeals
    When a verdict or sentence is unsafe, we assess appeal prospects promptly and pursue targeted remedies.

How We Build Your Defence

We prepare every case as if it will be tested in court. That discipline strengthens your position in negotiations and protects you at trial.

Early Intake and Risk Control
We map facts, secure disclosure pathways, and identify evidence to preserve—messages, devices, location data, third‑party records. Immediate risks around bail, employment, and travel are addressed with a plan.

Disclosure and Investigation
We demand full disclosure and audit it: officer notes, video, digital extractions, forensics, and warrant materials. Gaps are pursued. Where useful, we retain experts in digital analysis, forensics, or eyewitness science.

Charter Applications
Unlawful detentions, searches, or statements are challenged through focused applications to exclude evidence or stay proceedings. We do not hesitate to litigate Charter breaches.

Negotiation and Judicial Pre‑Trials
Armed with a trial‑ready brief, we press for withdrawals, diversionary resolutions, or meaningful charge/sentence reductions. If trial is required, we continue to shape the record in your favour.

Trial Preparation
We build a clear defence theory and evidentiary plan: targeted motions, measured witness strategy, and persuasive advocacy. Execution is deliberate and documented.

Leverage grows with early action. Contact Weisberg Law today to start your defence.

 

Early Steps to Protect Your Position

The first days influence outcomes. Sound steps now can prevent avoidable risk and strengthen your credibility.

  • Do not provide statements to police or third parties without legal advice.
  • Preserve potential evidence: texts, emails, photos, call logs, location data.
  • Identify potential sureties in case bail becomes necessary.
  • Follow tailored guidance on employment, school, and international travel.

 

Bail & Release Strategy

Release terms shape the rest of your case. We move quickly to secure bail with conditions that are realistic and defensible. Strong plans—credible supervision, practical boundaries, and clear compliance—help protect liberty without undermining the defence.

 

If a loved one was just arrested, call now so we can organize a bail plan and protect their rights from the start.

 

Evidence, Experts & Digital Realities

Modern prosecutions rely on records. We take a rigorous, methodical approach to evidence so that unreliable or unlawfully obtained material does not decide your case.

  • Digital Evidence: device extractions, cloud data, metadata, and communications. 
  • Forensics: DNA, fingerprints, ballistics, toxicology, and laboratory processes. 
  • Identification: reliability, suggestibility, and expert analysis on perception and memory. 
  • Search & Seizure: warrant sufficiency, informer privilege issues, and continuity. 

Expert assistance is retained when helpful. Strategic motions and evidentiary challenges are prepared early to strengthen negotiating power.

 

Appeals & Post‑Conviction Options

Trial errors, unfair rulings, or disproportionate sentences can be reviewed. Appellate work requires precise writing, careful record review, and targeted oral advocacy. We identify viable grounds, secure transcripts and exhibits, and advance focused remedies. Your future remains the priority even after sentencing.
