  Ben,
 As a Canadian living in the US I can clear up some of your confusion, since
this was all new to me as well a few years ago.
 In the US, a title is something unrelated to the vehicle registration. A
title signifies ownership of an object only. So things like cars, boats,
houses etc. have a title here, declaring who the owner is. A clear title
indicates there is only one owner, for example there is no loan outstanding
(lien).
 When a car is bought or sold here the new owner must apply for a new title
in his/her name, then deal with the vehicle registration, unlike Canada
where only the registration must be dealt with. I believe in Canada the bill
of sale effectively constitutes the title.
