Where does the 1 meter limit come from? There are no blade limits in the Criminal Code up here.

Spring assist such as Speed-Safe is legal. Knives which open ONLY by the push of a button or level on the handle are illegal.

"Concealed" blades such as the familiar dagger in a hair brush is illegal unless the overall length exceeds 30cm.

Oh, and belt buckle knives are frowned upon as well.
