Whether you're walking home late at night or going for a jog in an unfamiliar area, you may consider carrying tools or devices that make you feel safer.
In Canada, you cannot carry prohibited weapons and you also cannot carry any item with the intent to use it as a weapon against a person. Ordinary tools and products are perfectly legal to carry for legitimate purposes such as hiking, dog walking, or everyday utility.
If you ever use one of these lawful items to protect yourself in an emergency, police will usually investigate assault with a weapon (s.267) first so the situation can be reviewed under section 34, which governs self-defense.
Under s.34, the key questions are whether you reasonably believed you were being attacked, whether your response was proportional to the threat, and whether you carried the item for another lawful purpose (for example, animal protection or work). If you meet those conditions, your use of force is legally protected as self-defense, even if the object is later considered a “weapon.”

What Can We Carry In Canada To Feel Safe? Intent Matters
Think of a baseball, a metal water bottle or another heavy item like a skateboard that you are carrying around. None of these are weapons by design.
If you’re walking home from a game and someone attacks you, using your bat instinctively to defend yourself would normally be viewed as reasonable self-defense. You were carrying the bat for a lawful purpose, not to harm anyone, and you reacted to an imminent threat with proportionate force, exactly the type of situation protected under section 34 of the Criminal Code.
This is the same legal principle that applies to other multi-purpose safety tools, like a tactical pen or tactical flashlight. They serve everyday, legitimate purposes but can also be used to protect yourself in an emergency.
The key factor is intent. Carrying an object for the purpose of using it as a weapon is illegal under section 88. But if you’re carrying a lawful item for work, travel, or recreation, and you use it reasonably and proportionately to escape an assault your actions fall under self-defense protections in section 34.
In short: it’s your intent, purpose, and reasonableness that decide what’s legal, not the object itself.
10 Self Defense Tools You Can Carry In Canada
Is pepper spray legal in Canada? No. Pepper spray products designed for use on people are classified as prohibited weapons, and civilian possession is illegal.
Dog and coyote sprays are different. They’re registered animal repellents and completely legal to buy and carry for animal deterrence. Most come in small canisters that clip to your bag or keychain — practical for dog walkers, hikers, and anyone who spends time outdoors.
If you ever used one of these sprays during an assault, police would usually charge assault with a weapon (s.267) first so that the courts can assess the situation under section 34 of the Criminal Code. If your actions were necessary, reasonable, and proportionate to an imminent threat, section 34 can excuse the act as lawful self-defense. You can use bear spray for self defense in Canada here.
Important: Only carry sprays labeled for use on animals. Products intended for people are prohibited weapons under Canadian law, and even possessing them is a criminal offence.
Personal alarms emit an extremely loud 120–130 dB siren and flashing light to draw attention and scare off threats. They’re ideal for joggers, students, seniors, and anyone walking alone at night.
Pull the pin or press the button to activate the alarm and attract help immediately. These lightweight devices fit easily on a keychain or bag and are fully legal in Canada, since they’re non-violent safety tools rather than weapons.
A practical, all-purpose tool that’s legal to carry in Canada when used for camping, hiking, or work. Its durable stainless-steel design handles real emergencies, from cutting seatbelts to quick repairs. Just remember: carrying any knife for self-defense is illegal under section 88. If you use a multi-tool reactively in an assault, section 34 may protect you if your response was reasonable and proportionate to the threat.
A stainless-steel diversion bottle with a hidden compartment is a practical way to carry cash, cards, keys and small items out of sight. It’s a fully functional water bottle first and foremost and that everyday purpose keeps it lawful to carry. If you use the bottle reflexively to create space during an attack, section 34 may protect that defensive use so long as your response was reasonable and proportionate. Carrying it with the intent to use it as a weapon, however, risks a charge under section 88.
Keychains are legal to possess if they are primarily intended for another purpose (such as for carrying your keys). Avoid any keychain that is or functions as knuckle-dusters or other prohibited weapons. A plain key fob is fine. If a keychain tool is carried to use against a person, s.88 may apply.
Flashlights are lawful everyday tools. As with any object, if you carry one as a weapon you risk a s.88 charge, and if you use it on a person it will be treated as a “weapon” for s.267.
If you’re trapped in a car, you can break glass with a Tactical Pen (otherwise known as a windshield breaker). Buy it for writing and emergency glass-breaking only. Stating or forming an intent to use it on a person can trigger s.88. Read my full guide on the 10 best tactical pens here.
While the primary function of Apple’s AirTag is to keep tabs on our belongings, it can also help your personal safety. Your loved ones can use the Find My app, and easily check in on your location during your evening commute or jog.
A tire thumper is a vehicle-maintenance tool drivers use to check tire pressure and is lawful to keep in your car or toolbox for that purpose. If carried and used for its legitimate maintenance function, it is not a weapon. Carrying it with the clear purpose of using it on a person could attract a charge under s.88. If it’s ever used in an assault, police will likely investigate it as a weapon and the courts will decide under s.34 whether the defensive use was necessary and proportionate.
Safety whistles are simple and effective protective self-defense tools that can be used to attract attention and deter attackers. They’re perfectly legal in Canada and you can hang this whistle around your neck or leave it in a handbag or pocket.
