In Canada, the Criminal Coderegulates what types of knives can be legally carried. Section 90of the code prohibits carrying “prohibited weapons”, which includes:
- Knives that open automatically by gravity or centrifugal force or by hand pressure applied to a button, spring or other device in or attached to the handle (i.e. switchblades).
- Knives that have blades that open by centrifugal force (i.e. centrifugal knives).
- Knives that have blades over 10 cm (3.9 inches) in length, with the exception of hunting knives.
So pocket knives with shorter, non-spring assisted blades are generally legal to carry under the Criminal Code. Locking blades and one-handed opening knives are also usually allowed. However, municipalities and provinces can impose further restrictions.
