Is it legal to own a sword in Canada?

Answer 1

A sword is a weapon, so therefore one cannot import weapons into Canada.

Wrong. Swords and knives are perfectly legal for importation into Canada. Surprisingly enough the reverse is illegal. There are exceptions, such as switchblades, look at http://www.cbsa-asfc.gc.ca/publications/pub/bsf5044-eng.html for a list.

Answer 2

Yes it is, though carrying it around in public isn't necessarily legal. The following are illegal to own:

(a) a knife with a retractable or folding blade which, by design or through wear, will open by centrifugal force or gravity, or by a spring or similar device. This has been interpreted by the courts to include a butterfly knife;

(b) nunchaku or similar objects made up of hard, non-flexible sticks linked by a flexible length of chain. This includes objects where the sticks are replaced by, for example, pipes or other rigid pieces, and where the chain is replaced by rope, wire or other flexible material;

(c) shuriken or similar objects which are made of a hard, non-flexible material in an essentially two-dimensional regular geometric form with one or more sharp edges;

(d) manrikigusari or kusari or similar objects which are made up of geometrically-shaped hard weights or hand grips linked by rope, chain, wire or other flexible material;

(e) a push dagger, namely a knife where the blade is perpendicular to the handle;

(f) any item under 30 cm which looks like another object but which conceals a blade;

(g) spiked wristbands;

(h) blowguns;

(i) manually-triggered telescoping spring-loaded steel whips;

(j) morning stars or similar items consisting of a ball of metal or similar heavy material studded with spikes and connected to a handle by a length of rope, chain, wire or other flexible material;

(k) brass knuckles or similar items.
