I was wondering whether it is legally possible in Canada to modify a deactivated firearm for an art or display project, provided that none of the parts involved in the original deactivation are touched or reversed.

For example, if a firearm has already been properly deactivated to Canadian standards, with documentation, would it still be lawful to make cosmetic or structural changes such as cutting or shortening the barrel, replacing the stock, changing furniture, or attaching external hardware, as long as the modifications do not restore function or interfere with the welded, blocked, pinned, or otherwise deactivated components?
