Arson and Fire-Related Offences
Arson charges carry some of the most serious consequences in the Criminal Code. Our Calgary criminal defence lawyers build aggressive, evidence-focused defences from day one.
This page was written by the criminal defence lawyers at Hoare Claxton based on their experience appearing in Calgary courts. It is reviewed periodically for accuracy.
Arson is not treated as a minor property offence. Under the Criminal Code of Canada, arson charges carry maximum sentences ranging from five years to life imprisonment depending on the circumstances. If someone was endangered or killed, the consequences are catastrophic. If insurance fraud is alleged alongside the arson, you are facing two prosecution tracks at once.
Fire investigations are technically complex. Fire marshals, forensic engineers, and Crown-retained experts build these cases using evidence that most people cannot evaluate without specialist knowledge. That is exactly where your defence begins.

Arson Charges Under the Criminal Code
The Criminal Code contains several distinct arson provisions and the charge you face depends on the specific allegation and the circumstances surrounding the fire.
Arson Causing Disregard for Human Life (Section 433)
This is the most serious arson charge. It applies when a person intentionally or recklessly causes damage by fire or explosion and knows or is reckless about whether the life of another person would be endangered. The maximum sentence is life imprisonment. These cases are prosecuted aggressively and involve substantial expert evidence.
Arson of Own Property (Section 434.1)
Setting fire to your own property is still a criminal offence if it is done intentionally and causes damage. This provision is frequently charged alongside fraud allegations where insurance recovery is alleged as the motive. The maximum sentence is fourteen years.
Arson Causing Damage to Property (Section 434)
This charge applies when a person intentionally or recklessly causes damage by fire or explosion to property that is not wholly owned by that person. Maximum sentence is fourteen years.
Arson by Negligence (Section 436)
Arson by negligence arises when a person who owns or controls property departs markedly from the standard of care a reasonable person would exercise and fire results. Maximum sentence is five years. These charges often arise in industrial or commercial contexts.
Possession of Incendiary Material (Section 436.1)
Possession of incendiary material with intent to commit arson is itself a criminal offence, even if no fire is ever set. This charge frequently appears alongside the primary arson allegation.
Why Arson Cases Are Won or Lost on the Evidence
Fire investigation is not an exact science, and that is one of the most important things to understand about defending an arson charge.
The Crown's case typically rests on the opinion of a fire investigator or forensic expert who has concluded the fire was deliberately set. Those opinions can be challenged. The methodology used, the qualifications of the investigator, the alternative causes that were ruled out or never considered, and the physical evidence that was collected or missed during the investigation are all lines of attack an experienced defence team pursues from the moment we are retained.
In arson cases more than almost any other, retaining counsel immediately matters. Evidence degrades. Scenes get cleared. The sooner we are involved, the more we can do to preserve and contest the evidence the Crown is building their case on.
When Fraud Allegations Run Alongside Arson
A significant number of arson cases involve a parallel allegation of fraud, typically insurance fraud. The Crown's theory is that the fire was set to generate an insurance claim. When this is alleged, you are defending two distinct criminal matters simultaneously, each with their own evidentiary demands and procedural track.
Our team approaches these cases with a coordinated defence strategy that addresses both the fire science evidence and the financial evidence the Crown relies on to establish motive.
Your Charter Rights in a Fire Investigation
Fire investigations often begin before you are formally a suspect. Investigators attend the scene, speak to witnesses, and collect evidence. The line between an investigation into the cause of a fire and an investigation into you personally can shift quickly, and your Charter rights shift with it.
If investigators questioned you without advising you of your right to counsel, if your property was searched without proper authorization, or if statements were taken in circumstances that violated your rights, those are live grounds for challenging the admissibility of evidence against you. We look for those issues in every file.

Frequently Asked Questions
Can I be charged with arson if the fire started on my own property?+
Yes. Setting fire to your own property is a criminal offence under section 434.1 of the Criminal Code if it is done intentionally and causes damage. This charge is commonly laid when insurance fraud is alleged as the motive, meaning you can face both arson and fraud charges arising from the same incident.
How does the Crown prove arson?+
The Crown typically relies on the opinion of a fire investigator or forensic expert who has concluded the fire was deliberately set. They may also rely on witness evidence, financial records to establish motive, and surveillance footage. Fire investigation methodology is not infallible and defence experts regularly identify alternative explanations the Crown's investigator failed to consider.
What should I do if fire investigators or police want to speak with me?+
Call a lawyer before you speak to anyone. You have the right to remain silent and the right to retain counsel before answering any questions from fire investigators, police, or insurance adjusters. Statements made early in an arson investigation are frequently used as Crown evidence at trial. Do not assume that cooperating will help your position.
What is the difference between arson and mischief by fire?+
Mischief involving damage by fire can be charged under section 430 of the Criminal Code rather than arson in some circumstances, typically where the recklessness threshold for arson is not clearly met. The distinction matters because mischief carries lower maximum sentences. Which charge applies given the specific facts of your case is an important early analysis your defence lawyer should conduct.
