I assume that it is illegal to have a silencer on you gun in Canada - here in the states you can have one but must get a permit for it - it is amazing how they cut down on the noise that a gun makes - you can actually make your own using a oil filter - if your interested in seeing how such a silencer works just google silencers - would really help with you hearing - also while your at it google 22 lr accuracy - there is a site showing some guy shooting a 22 lr and hitting a target 500 yards away - interesting stuff
