I can't see this applying to super soakers.. and that is not what they are saying.

it seems clear that the bylaw is designed to limit the use of replica firearms and imitation firearms by kids in public.

There is already in place a Federal Criminal Code law prohibiting possession of replicas by anyone under 18. But on the enforcement side it is very unlikely to see kids playing with guns charged under the criminal code.
A bylaw with a fine is likely to serve as a more effective deterent than a criminal charge that will rarely be enforced.

Anything that keeps replicas out of the hands of minors is a good thing in IMO.
