Don't want to be a party pooper.
I'm also Canadian and I do war of 1812 reenactments.
I'm around swords quite a bit during the summer (Own a British navel boarding cutlass) and from what I gather it is illegal to own a sword in Canada if it is sharpened. I've not met anyone at a reenactment who's sword was sharpened, and I recall overhearing some men speaking with a police officer (Also a reenactor) who made the statement about dull swords.
The grey area is between what's a Knife and what's a Sword. I believe what you've purchased is distinctly a sword by design, and can't make the argument that it's just a long knife.
I think this law was put into place because of all the martial arts stuff. They don't want skilled "Ninjas" walking the streets with sharp swords. and because we're not allowed to arm ourselves in Canada for the purpose of self defense. A sword being strictly a "Weapon" for either offence or defense. and can't be (By design) used for any other purpose. And a sharp one is like owning a hand gun.
I have tried to find some information for you but can't come up with anything.
I'll email the guys in my group and see if I can come up with some more solid info for you
