Still talking about handguns, a private individual can sell a handgun to another private individual. But the transfer has to be approved by the Chief Firearms Officer (OPP in Ontario).
Both have to have a Restricted Possession and Acquisition Licence (RPAL) and this is verified by the CFO. The CFO will also verify that the buyer has a purpose, and the only purposes are target shooting and collecting.
The CFO will ask for proof of membership in an approved shooting club before approval of transfer, or proof of a bona-fide collection.
Under Bill C-71, the buyer will have to obtain an separate Authorization to Transport (ATT), and this is limited to transportation between home and approved Ontario ranges by the shortest route. Presently, the ATT is included in the PAL. The gun collector AFAIK, only has permission to transport from post office to home, or from seller's home to buyer's home. Under C-71, any other transportation to destinations not specified in the ATT must be approved by the CFO and a temporary ATT issued and carried by the owner. Every RPAL holder is very aware that not having the necessary paperwork when transporting handguns (trigger locked in a locked case hidden away from public view in the trunk of your car) can bring criminal charges, confiscation of all guns, revocation of PAL and a criminal record.
Dealers need not be involved, except when buying or selling.
Cars are not an essential item to own in big cities like Toronto, given the availability of public transit. They pollute, kill innocent people at the hands of the increasing number of reckless drivers. Your rising nanny state will eventually start limiting the use of cars after people get used to their other non-essential property and activities gradually get banned.
They are now regulating drones effective in June, by requiring them to be registered, and to get a license to operate them, just because some idiots in a foreign country far away (England) disrupted air traffic. When disruption happens anyway, by people unlicensed, they will then ban them from everyone, including licences people, and since the legal ones will have already been registered, will know exactly where to go to confiscate them. The criminals and crackpots will remain unaffected and undeterred, because they never obey the law.
