..At one point, I used to work for Customs...We registered smallcraft and the first two numbers followed by "E" designated the port where the boat was originally registered and follows the boat for its life...ie 7E was Chatham, Ontario, 75 E was Tilbury, Ontario..then later on, all Ontario registrations were registered with an"ON" number...then it moved to Service Canada and now I believe it is Transport Canada. I would have thought the registrations would have followed and would be filed with Transport now...how much information they can release to the Public might be a different matter...I know when I registered my boat with Service Canada in 2011, it retained the numbers..I think CPIC should be somehow linked to Transport records but it is restricted access to Police Agencies..
