Most knife advice written for a bushcraft audience is American, and the legal half of it does not survive the border. Canada regulates knives differently enough that the standard advice — carry what you like, conceal it if you want — is wrong here in ways that matter.
This is not legal advice. It is the reasoning behind clause L1-CUT-01, and why the specification asks for the knife it asks for.
There is no blade-length law
The single most common misconception. The Criminal Code sets no maximum blade length for knives, and no province sets a general one either. A 110 mm fixed blade is not inherently more illegal than a 70 mm one.
What the Code actually regulates is mechanism and intent:
- Automatic-opening knives are prohibited devices. Anything that opens by gravity, centrifugal force, or a button, spring, or other device in the handle. This captures switchblades, butterfly knives, and — through a series of border-services determinations — a surprising number of ordinary one-handed folders that can be flicked open.
- Concealment plus purpose. Carrying a weapon concealed is an offence, and a knife becomes a weapon when it is carried for a purpose dangerous to the public peace. Purpose is the operative word, and it is assessed on the facts.
A fixed blade in a sheath, worn openly, on the way to or during a field session, is the least ambiguous configuration available to you. That is not a legal guarantee — nothing is — but it is the shape of carry that gives an officer the least to work with.
Where it gets complicated
The Code is federal and uniform. Two other layers are not:
Municipal bylaws. Several Canadian cities restrict carrying knives in public places, parks, or on transit, and these vary considerably. A knife that is entirely lawful in the bush can be a bylaw problem on the bus getting there. Check the bylaw for the municipality you travel through, not just the one you train in.
Provincial park and Crown land rules. Regulations govern what you may cut, where, and whether you may have a fire — which is a bigger practical constraint on bushcraft than the knife law is. Cutting standing timber is prohibited in most provincial parks regardless of what you cut it with.
What this means for the specification
Clause L1-CUT-01 asks for a fixed blade, 90–110 mm, full tang, with a squared spine. Three of those four requirements are about competence. One is about law.
The fixed-blade requirement is the legal one. A fixed blade has no mechanism to be assessed against the prohibited-device provisions, and it is carried openly in a sheath rather than concealed in a pocket. It removes both of the questions the Criminal Code actually asks.
The rest is teaching:
- 90–110 mm is long enough to process wood for a shelter and short enough to carve controlled detail. Shorter loses leverage; longer loses precision and starts competing with the saw.
- Full tang because batoning is on the syllabus, and a partial tang under a baton is a failure waiting for the coldest day of the session.
- Squared spine so the knife strikes a ferro rod. This lets one tool serve two clauses, and it means a student who loses their striker still has fire.
Practical carry
Wear it on the belt or on the pack strap, openly, in a retaining sheath. Take it off before the drive home and put it in the pack — in a vehicle, a sheathed knife in a closed bag is unambiguous in a way that one on your hip is not.
If you are travelling through a city to reach a session, pack the knife in your main bag for the transit portion. The bylaw risk is real and entirely avoidable.
The honest summary
The knife most likely to cause you a legal problem in Canada is not a large fixed blade. It is a cheap one-handed folder with a flick action, carried in a pocket, in a city. The specification steers away from that category for teaching reasons, and the legal clarity is a genuine bonus rather than the driver.
Buy something plain, wear it openly, and know the bylaw for anywhere you pass through on the way.
