How long is the mandatory minimum sentence for illegal firearm possession in Mississauga?

23 May 2026 4 min read No comments Violent Crimes, Theft & Drug Offenses Mississauga
💡

In Canada, many mandatory minimum sentences for firearm offences were recently removed by federal legislation (Bill C-5) or struck down by the Supreme Court. However, illegal possession of a loaded restricted firearm in Mississauga is still aggressively prosecuted by the Crown Attorney, and convictions routinely result in sentences of 3 to 5 years in a federal penitentiary.

Being charged with a weapons offence by the Peel Regional Police is a life-altering event. The Canadian justice system treats firearm-related crimes with extreme severity to maintain public safety. Whether you were caught with an unregistered handgun during a traffic stop on Hurontario Street or accused of unsafe storage in your home, the stakes could not be higher.

For many years, the Criminal Code of Canada imposed strict mandatory minimum sentences for these offences. 🔍 Today, the legal landscape has shifted. While some automatic prison terms have been abolished, judges in Ontario still impose harsh penalties for illegal firearm possession. Understanding these nuances is critical for anyone facing these serious charges in the Peel Region.

Step-by-Step Process for Firearm Charges in Mississauga

If you are arrested in Mississauga, your criminal case will be handled at the A. Grenville and William Davis Courthouse in nearby Brampton. Navigating this complex process generally requires the expertise of an experienced criminal defence lawyer. Here is what you can expect.

Step 1: The Arrest and Bail Hearing

Firearm charges almost always result in an immediate arrest. 🚨 You will be held for a formal bail hearing, which is notoriously difficult to win for weapons offences. The Crown Attorney will likely argue for your continued detention. To secure release, your lawyer will usually need to present a strong plan involving a strict surety (a person who guarantees your good behaviour) and potentially house arrest.

Step 2: Reviewing the Crown’s Disclosure

Once released, your lawyer will request the “disclosure” from the Crown. This package contains all the evidence the Peel Regional Police have gathered against you, including witness statements, search warrants, and ballistic reports. Your legal team will carefully review this to see if your Charter rights were violated, such as an illegal search of your vehicle.

Step 3: Negotiating or Going to Trial

Many firearm cases involve challenging the evidence in the Superior Court of Justice or the Ontario Court of Justice. 💬 If the police conducted an unlawful search, your lawyer may apply to have the firearm excluded as evidence. If a trial is necessary, the Crown must prove beyond a reasonable doubt that you had knowledge and control of the illegal weapon.

How Much Does it Cost in Mississauga?

Defending against an indictable offence involving a firearm is a significant financial commitment. Because these cases are highly technical and carry the risk of federal prison time, legal fees reflect the complexity of the work.

  • Initial Retainer: Most experienced criminal defence lawyers in the Greater Toronto Area ask for an initial retainer between $5,000 and $10,000 CAD.
  • Bail Hearing: A contested bail hearing for a firearm charge typically costs between $2,500 and $5,000 CAD.
  • Going to Trial: If your case proceeds to a full trial, total legal fees can easily range from $20,000 to over $50,000 CAD.

How Long Does the Process Take?

Criminal proceedings in Ontario move slowly due to heavy court backlogs. Resolving a firearm charge in Mississauga typically takes anywhere from 12 to 24 months. Under the Canadian Charter of Rights and Freedoms, you have the right to be tried within a reasonable time, which the Supreme Court has defined as 18 months for provincial court cases and 30 months for cases in the Superior Court.

Comparing Offence Types: Summary vs. Indictable

Frequently Asked Questions (FAQ)

Do I have to go to jail for a first-time firearm offence?

While not strictly mandatory in every single case, jail time is highly likely for illegal handgun possession, even for first-time offenders, unless your lawyer can secure an acquittal or negotiate a very exceptional plea deal.

What happens if the gun was not mine, but in my car?

You can still be charged with constructive possession. The Crown Attorney must prove that you knew the firearm was there and that you had a measure of control over it.

Are airsoft or BB guns considered firearms in Canada?

It depends on their muzzle velocity. If a replica or pellet gun shoots at a high enough speed, it can be legally classified as a firearm. Furthermore, using a replica during a crime is treated exactly like using a real firearm.

Can I get a conditional sentence (house arrest) for a gun charge?

Recent changes in federal law (Bill C-5) have made Conditional Sentence Orders (CSOs) available for some weapons offences, but judges are extremely hesitant to grant them for serious crimes involving loaded, restricted firearms.
