    15 Common Mistakes in Criminal Cases

    Learn what to avoid when facing criminal charges in Ontario to protect your rights and achieve the best possible outcome

    Last reviewed: 2026-04-26T00:00:00Z

    1. Talking to Police Without a Lawyer

    The Mistake: Many people believe they can "explain their way out" of charges or that remaining silent makes them look guilty. They give statements to police hoping to clear things up.

    Why It's Dangerous: Police are trained interrogators. Anything you say can be taken out of context, misinterpreted, or used against you. Even innocent statements can be twisted. You cannot "talk your way out" of charges - that's what court is for.

    What to Do Instead:

    • Politely invoke your right to silence: "I wish to speak to a lawyer"
    • Do not answer questions beyond identifying yourself
    • Contact a criminal lawyer immediately - use duty counsel if needed
    • Do not waive your rights under any circumstances

    2. Not Hiring a Lawyer or Refusing Legal Aid

    The Mistake: Trying to represent yourself or refusing free legal assistance because of pride, misconceptions about Legal Aid, or thinking the charges aren't serious enough.

    Why It's Dangerous: Criminal law is incredibly complex. Judges, Crown attorneys, and police are legal professionals. Without proper representation, you don't know what you don't know - from Charter challenges to disclosure rights to negotiation tactics.

    What to Do Instead:

    • Apply for Legal Aid Ontario if you meet financial requirements
    • Speak with duty counsel at court (free for everyone)
    • Consider borrowing money or payment plans for a private lawyer
    • Remember: A criminal record costs far more than legal fees

    3. Breaching Bail Conditions

    The Mistake: Violating bail conditions because you think they're unreasonable, forgetting about them, or believing "just this once won't matter."

    Why It's Dangerous: Breaching bail (Form 5.1, Form 11, or Form 32) is a separate criminal offence carrying up to 2 years in jail. It makes getting bail in the future nearly impossible and shows the court you can't follow orders.

    What to Do Instead:

    • Write down all bail conditions and review them daily
    • If conditions are too restrictive, apply for a bail variation
    • Set phone reminders for curfews and reporting times
    • Ask your lawyer or surety if you're unsure about any condition
    • Never contact prohibited persons, even if they contact you first

    4. Missing Court Dates

    The Mistake: Forgetting court dates, thinking one missed appearance won't matter, or being too scared/embarrassed to attend.

    Why It's Dangerous: Missing court results in a warrant for your arrest, an additional charge for failure to appear (up to 2 years jail), and loss of bail. Future bail becomes extremely difficult or impossible.

    What to Do Instead:

    • Mark all court dates in multiple calendars
    • Set multiple reminders (1 week, 1 day, morning of)
    • Plan transportation in advance
    • If emergency prevents attendance, call your lawyer and court immediately
    • Arrive early - courts are busy and delays happen

    5. Discussing Your Case on Social Media

    The Mistake: Posting about your case, charges, or the alleged incident on Facebook, Instagram, Twitter, or other social media platforms.

    Why It's Dangerous: Police and Crown attorneys regularly monitor social media. Your posts can be used as evidence, contradicting your defence. Photos, videos, check-ins, and even "likes" can damage your case.

    What to Do Instead:

    • Do not post anything about your charges or case
    • Set all profiles to private
    • Consider deactivating accounts temporarily
    • Tell friends/family not to post about your case
    • Assume everything online will be seen by police and Crown

    6. Discussing Your Case with Friends or Family

    The Mistake: Openly discussing case details, evidence, or strategy with friends, family, or other inmates (if in custody).

    Why It's Dangerous: These people can be compelled to testify against you. Jail informants are common. There's no privilege protecting these conversations (unlike lawyer-client).

    What to Do Instead:

    • Only discuss case details with your lawyer
    • Tell loved ones you can't discuss specifics
    • Never discuss your case with cellmates or other accused persons
    • Be aware that jail phones are often recorded

    7. Not Reviewing Disclosure Carefully

    The Mistake: Letting your lawyer handle everything without reviewing the Crown's evidence package yourself, or not identifying errors and inconsistencies.

    Why It's Dangerous: You know the facts better than anyone. You can spot inaccuracies, missing evidence, or inconsistencies your lawyer might miss. This information is crucial for your defence.

    What to Do Instead:

    • Read every page of disclosure carefully
    • Make notes of errors, inconsistencies, or missing information
    • Provide your lawyer with your observations
    • Ask questions if you don't understand something

    8. Consenting to Searches Without a Warrant

    The Mistake: Allowing police to search your home, car, or phone without a warrant because you "have nothing to hide" or feel pressured.

    Why It's Dangerous: You can't predict what police will find significant. Innocent items can be interpreted as evidence. Consenting waives your Charter rights and makes evidence admissible.

    What to Do Instead:

    • Politely refuse consent: "I do not consent to any searches"
    • If police have a warrant, do not resist but say you don't consent
    • Do not touch or point to anything
    • Document what was searched and seized
    • Inform your lawyer immediately

    9. Lying to Your Lawyer

    The Mistake: Withholding information or lying to your lawyer because you're embarrassed, worried they'll judge you, or think it's not relevant.

    Why It's Dangerous: Your lawyer needs all facts to prepare the best defence. Surprises at trial can destroy your case. Lawyer-client privilege protects your communications - they cannot share what you tell them.

    What to Do Instead:

    • Be completely honest with your lawyer about everything
    • Share information even if you think it's bad for your case
    • Trust in solicitor-client privilege
    • Let your lawyer decide what's relevant

    10. Pleading Guilty Without Understanding Consequences

    The Mistake: Pleading guilty to "get it over with," without understanding the long-term consequences or exploring other options like peace bonds or withdrawal.

    Why It's Dangerous: A criminal conviction is permanent and affects employment, travel (especially to USA), professional licensing, volunteering, and more. You cannot take back a guilty plea once entered.

    What to Do Instead:

    • Discuss all possible resolutions with your lawyer
    • Understand what a conviction means for your specific situation
    • Consider peace bonds (s. 810) which avoid convictions
    • Explore diversion programs if available
    • Only plead guilty when it's truly in your best interest

    11. Contacting Victims or Witnesses

    The Mistake: Trying to convince the victim/complainant to drop charges, apologizing, or attempting to "work things out" directly.

    Why It's Dangerous: This usually violates bail conditions and can result in new charges for witness intimidation or obstruction of justice. Even well-intentioned contact can be interpreted as threatening.

    What to Do Instead:

    • Have no contact whatsoever with complainants or witnesses
    • Don't use third parties to pass messages
    • If they contact you, do not respond and inform your lawyer
    • Let your lawyer handle any negotiations

    12. Not Addressing Underlying Issues

    The Mistake: Ignoring substance abuse, mental health issues, or anger management problems that contributed to the charges.

    Why It's Dangerous: Courts want to see rehabilitation. Taking proactive steps shows remorse and reduces the risk of reoffending, leading to better outcomes at sentencing.

    What to Do Instead:

    • Enroll in counselling or treatment programs immediately
    • Attend AA/NA meetings if substance abuse is a factor
    • Get documentation of all steps taken
    • Show the court you're taking responsibility

    13. Poor Courtroom Behaviour

    The Mistake: Being late, dressing inappropriately, showing disrespect, chewing gum, using phones, or displaying attitude in court.

    Why It's Dangerous: Judges notice everything. Poor behaviour suggests lack of remorse, disrespect for the justice system, and inability to follow rules - all factors that can influence bail decisions and sentencing.

    What to Do Instead:

    • Arrive at least 30 minutes early
    • Dress professionally (business casual minimum)
    • Turn off your phone completely
    • Stand when the judge enters/exits
    • Address the judge as "Your Honour"
    • Never interrupt or speak out of turn

    14. Continuing Criminal Activity

    The Mistake: Committing new offences while on bail or during court proceedings.

    Why It's Dangerous: New charges while on bail virtually guarantee detention, make future bail impossible, demonstrate to the court you cannot follow rules, and result in harsher sentences on all charges.

    What to Do Instead:

    • Stay completely law-abiding while your case is pending
    • Avoid situations that could lead to trouble
    • Change your lifestyle if necessary
    • Surround yourself with positive influences

    15. Not Being Patient with the Process

    The Mistake: Getting frustrated with delays and wanting to "just get it over with" by pleading guilty or accepting a bad deal.

    Why It's Dangerous: Criminal cases take time - sometimes 12-18+ months. Rushing can result in accepting deals that aren't in your best interest. Sometimes delay works in your favor as witnesses forget details or Crown's case weakens.

    What to Do Instead:

    • Trust your lawyer's timeline and strategy
    • Use the time to address underlying issues and build your case
    • Understand that good outcomes take time
    • Focus on compliance with bail conditions and rehabilitation
