Does Canada Have Castle Law? Here’s What Self-Defense Really Means

The term Castle Doctrine often appears in American news. It's the idea that your home is your castle and you have the right to use force, even deadly force, to defend it from intruders.
Canada does not have a Castle Doctrine. Here, the Criminal Code sets a different standard. You can protect yourself, your family, and your property, but only if the force you use is considered reasonable for the situation.
In practice, that means if someone breaks into your home without a weapon, you cannot respond with deadly force.
This difference has fueled debate about whether Canada should copy the U.S. model. Some argue for stronger legal protection for homeowners, while others believe the current limits are necessary to prevent misuse.
So what does Canadian law actually allow when you defend your home and family?
Self-Defense in Canada vs. the U.S. Castle Doctrine
Where American Castle Doctrine laws often shield homeowners automatically, Canadian courts judge each case individually. Instead of presuming deadly force is justified, judges and juries look at whether your actions were proportionate to the threat, whether other options were available, and how immediate the danger was.
This means Canadians do not have the same automatic legal protection that many Americans do.
Every confrontation is tested against the standard of reasonableness, which makes outcomes less predictable but also prevents a blanket right to extreme force.
How Canadian Self-Defense Law Works
Canadian law on self-defense is found mainly in Section 34 and Section 35 of the Criminal Code. These sections cover defending yourself, other people, and your property.
The core rule is that your actions must always be reasonable for the situation.
Section 34: Defending Yourself or Others
You can use force if you believe someone is using, or about to use, force against you or another person.
Your actions must be taken to protect yourself or others.
The response must be reasonable, based on the circumstances.
Courts look at factors such as:
Was the threat immediate?
Did the other person have a weapon?
Did you have other options besides fighting back?
How serious was the danger?
Section 35: Defending Property
You can use force to stop someone from entering, taking, or damaging your property.
You must believe you have the right to that property.
Again, the force has to be reasonable.
Importantly, you cannot use deadly force to protect property alone. Lethal action is only allowed if you reasonably believe your life, or someone else’s life, is in immediate danger.
Difference Between Reasonable vs Not Reasonable Force
Canadian courts expect your response to match the threat. For example, if an unarmed intruder enters your home, physically pushing them out or holding them until police arrive would likely be considered reasonable.
If the intruder has a weapon, using objects around you to block or protect yourself could also fall within the law, as long as your response is limited to stopping the threat.
By contrast, shooting an unarmed person who is only trying to steal property would almost certainly not be seen as reasonable.
The same goes for attacking someone after they are already fleeing, or using deadly force when your life or safety is not actually at risk. In these situations, the law would see your actions as excessive.
Castle Doctrine Canada: 3 Self-Defense Cases That Shaped the Debate
Ali Mian – Milton, Ontario (2023)
In February 2023, 22-year-old Ali Mian woke to find several armed men breaking into his Milton, Ontario home. The intruders physically assaulted his mother, and Mian, who was a licensed gun owner, fired his handgun and killed one of them.
Police charged him with second-degree murder. After reviewing the evidence, the Crown later withdrew the charge, stating there was no reasonable prospect of conviction because his actions could be understood as self-defense.
This case showed that when intruders are armed and a family member is under direct attack, Canadian courts may accept deadly force as reasonable.
Peter Khill – Hamilton area, Ontario (2016 incident, conviction upheld 2023)
In 2016, Peter Khill noticed someone trying to break into his truck outside his rural home.
He went outside with a shotgun and confronted 29-year-old Jon Styres, an Indigenous man who was unarmed. Khill fired two shots, killing him.
A jury later convicted Khill of manslaughter, and he was sentenced to eight years in prison, which was later reduced to six on appeal. In 2023, the Supreme Court of Canada declined to hear further appeal, leaving the conviction in place.
This case highlighted that using deadly force against someone outside the home, especially if they are unarmed, can be judged as disproportionate and as a criminal act.
Gerald Stanley – Rural Saskatchewan (2016 incident, verdict 2018)
Another high-profile case unfolded in Saskatchewan. In 2016, farmer Gerald Stanley shot and killed 22-year-old Colten Boushie, a Cree man, who had driven onto his property with friends.
Stanley argued that the shooting was accidental and that he had fired in self-defense while trying to protect his family and property. In 2018, a jury found him not guilty of both second-degree murder and manslaughter.
The verdict sparked national debate and protests, raising questions about race, rural property rights, and how self-defense laws are applied.
How to Defend Yourself Without Breaking the Law
Canadian law does not allow you to carry firearms or most weapons for personal protection. But there are legal and effective ways to increase your safety at home and in daily life.
Wildlife spray: Carrying bear spray or dog (coyote) deterrent spray is legal when used for its intended purpose. While it cannot be marketed as a self-defense weapon, many Canadians keep it on hand for outdoor use. It can also help in emergencies when facing a real threat.
Alarms and noise deterrents: Personal alarms or air horns draw attention quickly, which is often enough to scare off an intruder. Loud noise is one of the simplest and safest defenses.
Home security basics: Simple steps like better locks, motion lights, and doorbell cameras can reduce risk and provide evidence if something happens.
Martial arts training: Learning a martial art like jiu-jitsu gives you practical self-defense skills that do not rely on weapons. Even a few basic moves can help you escape from holds, break free if grabbed, or use leverage against someone larger.
Tactical flashlights: A strong flashlight with a strobe setting can disorient an attacker long enough for you to get away. These devices are completely legal and double as everyday tools for the home or outdoors.
Together, these options give you ways to protect yourself and your family while staying within the law. They focus on prevention, deterrence, and non-lethal defense, which Canadian courts are more likely to view as reasonable.
All Your Questions Answered On Castle Doctrine Canada
Does Canada have a Castle Doctrine? No. Unlike many U.S. states, Canada does not have a Castle Doctrine law. Instead, the Criminal Code requires that any force you use in self-defense is reasonable and proportionate to the threat.
Can you use lethal force to defend property in Canada? No. Deadly force is only justified if you reasonably believe your life or someone else’s life is in immediate danger. Protecting property alone does not allow for lethal force.
Do you have to retreat if someone breaks into your home in Canada? No. Canadian law does not impose a legal duty to retreat from your home. However, courts may consider whether you had the option to avoid using force when judging if your actions were reasonable.
What counts as reasonable force under Canadian law? Reasonable force is measured by whether your actions matched the threat. For example, pushing out an unarmed intruder may be reasonable, while shooting someone who is not armed or threatening your life would not be.
