Are Brass Knuckles Illegal in Canada?

Yes. Metal brass knuckles are illegal in Canada.

Under Canadian federal law, brass knuckles and similar metal devices designed to fit over the fingers are classified as prohibited weapons. That means the legal issue is not simply whether someone uses them. Unauthorized possession, manufacturing, transferring, and importing can also create serious legal consequences.

But there is an important detail: not every product that looks like brass knuckles is automatically classified the same way. The material, design, and circumstances can matter.

1-minute quick summary:Metal brass knuckles are prohibited weapons in Canada. Federal regulations specifically cover brass knuckles and similar metal devices with finger holes designed to fit over the fingers. Knowingly possessing a prohibited weapon without authorization can be an offence under section 92 of the Criminal Code, with a maximum penalty of 10 years' imprisonment. Manufacturing or transferring prohibited weapons can also be offences. CBSA says plastic knuckles generally do not meet the specific definition of brass knuckles, but that does not mean every knuckle-shaped product is automatically legal. (CBSA)

This article is general legal information, not legal advice. If you are dealing with a police investigation, seizure, or criminal charge, speak with a qualified Canadian criminal lawyer.

How Does Canadian Law Define Brass Knuckles?

The first thing to understand is that Canadian law does not only cover objects literally made from brass.

The federal rules cover “brass knuckles” and similar devices consisting of aband of metal with one or more finger holes designed to fit over the fingers of the hand.

The Canada Border Services Agency provides additional guidance and explains that brass knuckles can be made from any type of metal. It also notes that they do not have to have four finger holes. Variations such as “half knuckles,” with two finger holes, can also fall within the definition. (CBSA)

That means the name used to market a product is not necessarily what determines its legal classification.

The Criminal Code defines a “prohibited weapon” to include weapons that are prescribed as prohibited by regulation. The regulations then identify the specific weapons that fall into that category. (Justice Laws)

Brass knuckles are one of those listed weapons.

Are Brass Knuckles Illegal to Possess in Canada?

Yes, unauthorized possession can be a criminal offence.

Section 92(2) of the Criminal Code states that a person commits an offence if they possess a prohibited weapon while knowing they do not hold a licence that authorizes that possession. Section 92(3) provides for a maximum penalty of 10 years' imprisonment for an indictable offence under the section. (Justice Laws)

This is important because the law does not require someone to actually use the brass knuckles before possession becomes a legal issue.

Simply saying:

• “I never used them.”

• “I kept them at home.”

• “They were just for my collection.”

• “I had them for protection.”

does not automatically make possession lawful.

The circumstances of a particular case can matter, but the basic rule is straightforward: metal brass knuckles are classified as prohibited weapons under Canadian federal law.

What About Manufacturing, Selling or Transferring Brass Knuckles?

Canadian weapons law also deals with what happens before or after possession.

The Criminal Code contains separate offences dealing with the unauthorized manufacture and transfer of prohibited weapons. The definition of “transfer” is also broad and includes actions such as selling, giving, lending, sending, shipping, distributing, or delivering. (Justice Laws)

So the issue is not limited to someone physically carrying a prohibited weapon.

Manufacturing a prohibited weapon or transferring one to another person can raise separate criminal-law issues.

For businesses and individuals, this is particularly important because simply describing a transaction as a “sale,” “gift,” or another type of transfer does not necessarily change how the law applies.

Can You Import Brass Knuckles Into Canada?

Importing metal brass knuckles into Canada can also create legal problems.

The Canada Border Services Agency specifically identifies brass knuckles as a prohibited weapon for importation purposes. Its guidance explains that brass knuckles can be made from different types of metal and can come in different designs. (CBSA)

CBSA officers can assess goods entering Canada, and prohibited goods can be stopped or seized at the border.

This means buying an item outside Canada does not make it legal to bring it into Canada.

If there is uncertainty about a particular product, it is important to determine its legal classification before attempting to import it.

Are Plastic Knuckles Legal in Canada?

This is where things become less straightforward.

The CBSA's current guidance says that plastic knuckles do not fall within the specific definition of “brass knuckle.”

That does not mean, however, that every plastic or non-metal product shaped like a knuckle is automatically legal in every situation.

The CBSA specifically notes that some goods may not meet the definition of a particular prohibited weapon while their misuse can still be punishable under other laws. (CBSA)

So it is better to avoid making a blanket statement such as:

“Plastic knuckles are legal in Canada.”

A more accurate explanation is:

CBSA states that plastic knuckles generally do not meet the specific definition of brass knuckles, but their misuse may still be punishable under other laws.

That distinction is important because Canadian weapons law can depend on the specific design of an object and the circumstances involved.

What About Brass-Knuckle Knives?

Brass-knuckle knives can be more complicated because they combine a knife blade with a knuckle-style handle.

According to CBSA guidance, the handle is what must be considered when determining whether a brass-knuckle knife falls under the brass-knuckle definition. For the product to be prohibited on that basis, the handle must itself be effective as a weapon and meet the definition of brass knuckles. (CBSA)

The blade can also raise separate legal questions depending on its design and mechanism.

The important point is that a product should not be classified solely by its marketing name or a photograph.

Can You Have Brass Knuckles for Self-Defence?

There is no general self-defence exception that makes possession of metal brass knuckles lawful.

Canadian self-defence law deals with when a person may respond to a threat. It does not generally create permission to possess a prohibited weapon in advance.

So describing brass knuckles as being “for protection” does not automatically change their legal classification.

This is an important distinction:the purpose someone claims for possessing an object does not necessarily determine whether the object itself is a prohibited weapon.

For a specific situation, professional legal advice is the appropriate way to determine what rights and obligations apply.

What Are the Penalties for Possessing Brass Knuckles?

The potential consequences depend on what the person is alleged to have done.

For unauthorized possession, section 92(2) of the Criminal Code applies to prohibited weapons, and section 92(3) provides for a maximum of 10 years' imprisonment when prosecuted by indictment. (Justice Laws)

That is a maximum statutory penalty, not an automatic sentence. The actual outcome of a case depends on the facts, the charge, the applicable law, and the court process.

Manufacturing or transferring a prohibited weapon can involve separate Criminal Code provisions and potentially different penalties.

This is why it is important not to confuse a maximum penalty written in legislation with what will necessarily happen in an individual case.

Keeping an item at home does not automatically remove it from Canada's prohibited-weapons rules. Unauthorized possession can still be an offence. (Justice Laws)

Are plastic brass knuckles illegal in Canada?

CBSA says plastic knuckles generally do not fall within the specific definition of brass knuckles. However, that should not be interpreted as saying every plastic or knuckle-shaped product is automatically legal in every circumstance. (CBSA)

The Bottom Line: Are Brass Knuckles Illegal in Canada?

Yes. Metal brass knuckles are prohibited weapons in Canada.

Canadian federal law specifically covers brass knuckles and similar metal devices with finger holes designed to fit over the fingers. The Criminal Code then makes unauthorized possession of a prohibited weapon an offence. (Justice Laws)

The rules go beyond possession. Canadian law also addresses the unauthorized manufacturing and transferring of prohibited weapons, while CBSA rules cover their importation into Canada. (CBSA)

Plastic knuckles are a different question. CBSA states that plastic knuckles generally do not meet the specific definition of brass knuckles, but their status should not be reduced to a simple “legal” or “illegal” label without considering the specific product and circumstances. (CBSA)

The key takeaway is simple:

If a product is made of metal and designed to fit over the fingers like brass knuckles, Canadian federal law treats that type of device as a prohibited weapon.
