This makes the rule page useful for comparison without creating a second data source.
Australia
Australia does not have one uniform civilian pepper-spray rule. Victoria Police says capsicum spray is illegal to purchase, possess, carry or use without a Governor in Council exemption or Chief Commissioner approval, while WA regulations expressly allow carrying or possessing a capsicum spray weapon for lawful defence where the person has reasonable grounds to apprehend circumstances may arise.
Austria
Austria’s official pepper spray page treats pepper spray as a weapon but allows civilian possession subject to rules, and states it may only be used exclusively in self-defence.
Belgium
Belgian Justice lists self-defence aerosols and sprays as prohibited weapons. Prohibited weapons cannot lawfully be possessed, bought, transported or carried by civilians.
Canada
In Canada a spray designed to be used against humans is a prohibited weapon but animal repellents labelled only for animal use are treated differently.

Why the page is intentionally light
The new site should show a stable layout, a stable route, and clear source slots before the dataset is scaled up again. That keeps management simple and makes later official-source population safer.
