How do I transfer a RESTRICTED fire arm to a buyer

[RangeBob]

Well you need to gather the buyer contact info ( phone/email.. Other then a username on a forum ) Name and PAL

And address.
The Canadian Firearms Program will want the buyer's PAL/Expiry, Name (as it appears on the PAL) and Address (the one the PAL is registered to). Maybe something else, but they'll want those four.
