Knife Laws in Montreal?

I was wondering if anybody knew what the knife laws were like in montrea/Quebec. I would love to carry a pocket knife but I’m not sure what I’m allowed to carry. I often find myself in situations (legal) where a knife would be really useful.

Memorandum D19-13-2

20. Not all weapons are necessarily prohibited. Any weapon that is not specifically prohibited by law will generally be admissible. If a weapon does not meet one or more of the definitions contained in the list of prohibited weapons, please consult the â??Other weaponsâ?? section below.
21. The definition of prohibited weapon has two components: 1) â??Paragraph (a) weapons, being automatic, centrifugal, or gravity knives; and 2) â??Paragraph (b) weapons, being those laid out explicitly in the Criminal Code subsection 84(1) Regulations, Part 3. Section 84(1) of the Criminal Code states that a prohibited weapon is:
(a) a knife that has a blade that opens automatically by gravity or centrifugal force or by hand pressure applied to a button, spring, or other device in or attached to the handle of the knife; or
(b) any weapon, other than a firearm, that is prescribed to be a prohibited weapon.
Memorandum D19-13-2
â??Paragraph (a)â?? weapons
22. Weapons that fall under paragraph (a) include the following:
(a) Automatic knife (switchblade) â?? An automatic knife that houses a blade that will open automatically by hand pressure applied to a lever or button in or attached to the handle (but not on the blade) of the knife. The blade is released by pressure on the lever or button, and opens with the assistance of an internal spring or mechanism.
(b) Centrifugal knife (folding knife, butterfly knife, balisong knife) â?? A centrifugal knife is one that opens automatically through the use of centrifugal force. Centrifugal force may be defined as a force, arising from the body’s inertia, which appears to act on a body moving in a circular path and is directed away from the centre around which the body is moving. That is, centrifugal force is established when the blade of the knife may be opened with the flick of the wrist. Note that extra manipulation and a requirement for some skill to release the blade do not prevent a knife from being a prohibited weapon. A balisong or butterfly knife is a form of centrifugal knife with two handles that counter-rotate around the blade such that, when closed, the blade is concealed within grooves in the handles.
(c) Gravity knife â?? A gravity knife is a folding knife which may be opened automatically by force of gravity. The knife may be additionally controlled by a lever or button, but typically, applying pressure to such a device and pointing the knife downward will result in the knifeâ??s blade releasing and locking into place.
Exception: The following type of knife does not generally meet the definition of prohibited weapon, and therefore it is not within the purview of TI 9898.00.00. The misuse of this knife may nonetheless be punishable under other laws.
23. Torsion bar assisted-opening knives (folding knife, speed-safe knife, spring-assisted knife) â?? Folding knives that use an internal â??torsion barâ?? to assist in opening them with one hand. The heart of this opening system is the torsion bar in the handle of the knife. In order to open the knife, the user must apply manual pressure to a thumb stud or other protrusion on the blade, thereby overcoming the resistance of the torsion bar. After the blade is moved partially out of the handle by this manual pressure, the torsion bar takes over.
24. In some cases, torsion bar assisted-opening knives can be opened automatically by gravity or centrifugal force. If this is the case, these knives would fall within the definition of prohibited weapon, and be prohibited under TI 9898.00.00 unless an exemption in that tariff item applies

Concealed weapons like sword canes are legal if the blade is over 30cm. And from the criminal code…

[i]CCC S. 89 (1) Carrying weapon while attending a public meeting - Every person commits an offence who, without lawful excuse, carries a weapon, a prohibited device or any ammunition or prohibited ammunition while the person is attending or is on the way to attend a public meeting.

CCC S.90 (1) Carrying concealed weapon - Every person commits an offence who carries a weapon, a prohibited device or any prohibited ammunition concealed, unless the person is authorized by the Firearms Act to carry it concealed.

Additionally, as interpreted by the CCC S. 2 Definitions - “Weapon” means any thing used, designed to be used or intended for use
(a) in causing death or injury to any person, or
(b) for the purpose of threatening or intimidating any person and, without restricting the foregoing, includes a firearm.[/i]

So the intent matters as much as the weapon. Carrying for self-defense is illegal. But in the end, the police with do whatever they want and charge whoever they want if they feel like it. People have been charged carrying a Swiss army knife with a half inch blade. Oh, and you live in Quebec, so God knows how that changes things…

Does a thumb-stud knife classify under 21 a?

I would say No. It requires you to manually open it, it doesn’t open by a button/spring combo. Also, see where it mentions that the button is attached to the handle, not the blade in that section. If you can “flick” it open then Yes, it would fall under the “gravity” section.

Fantastic! Thanks MrZsasz

honest question, not being a troll-

how does one determine if it is centrifugal force? i have a knife that is meant to be opened with your thumb but the pin is loose so you can sling it open if you whip it hard enough. it doesnt do it everytime, but it is capable of doing it.

would that be a gray area or out right banned?

begin trolling-
centrifugal force is more an engineering term that can be argued doesnt even exist. it is really angular force/acceleration/momentum, centripetal if you will. think the cops (do they have different names up there?) would get into a discussion about it? what about the courts?

As far as your first question, I think this is quite relevant since given enough force, almost any knife could be opened using centrifugal force.

As to the second question, centrifugal force does exist in certain coordinate systems. Since forces are defined based on the coordinate system anyway, it’s not really accurate to say that centrifugal force is any more or less real than centripetal force or any other force.

That would count. The idea being if someone bought a plain jane knife and loosened the pins so that it could be flicked open, then it falls under the prohibited definition. So if you get stopped and the knife does open for a cop like that, trouble. If it doesn’t, you would just get lucky. And I am willing to bet that arguing the definition of centrifugal force to a judge/cop would just make you a bigger target. hah.

First question: I hear it’s at the discretion of the cop or judge.

Second question: centrifugal can exist in order to describe the acceleration experienced in the frame of the moving mass being pulled away from the center of motion. It is imaginary but not necessarily doesn’t exist. In reality it’s just the interpretation of the particular frame of constantly changing linear force…or so I understand.

interesting on the first question. the intent of the knife would likely not be considered, but its actual operation.

and on the second - lighten up guys, it was a joke. like i said- it could be argued that it doesnt exist. i didnt say it doesnt.

and i would be willing to bet i would end up doing time in a federal pound-me-in-the-ass pen if i tried to argue reference frames and motive forces and inertia. at least contempt of court…

Say “Hello” to people and if they respond in French please stab them about the face, neck and chest.

Non-inertial reference frames generate these pseudo forces. The earth is one, on a large scale, hence the Coriolis force. A banking car as well.

When people say centrifugal is not a force, they mean its not a fundamental force, gravity, electro-weak or strong nuclear.

I have sent this question to a Mtl. Cop friend of mine. I will get back to you with his take on it, if he answers.

I now see why you’re no longer in Canada.

They don’t have an extradition treaty with Japan?

Can anyone explain why an “automatic” knife is outlawed when a folding blade is not? Are solid tang knives legal?

according to the laws posted a fixed blade knife is legal.

Is there a blade length limit? In Michigan it is 3-1/2" I believe.

You are quoting the section to do with assisted opening knives, ex Kershaw’s speedsafe, that isn’t what he is asking. He is asking about a knife that he can flick open and that falls under folding knife in 22b.
