Born around 1929.
Computer records are pretty good after 1998.
Criminal convictions are pretty good on computer, at least after 1970. But anything else computerized is probably shaky between 1970 and 1998.
My bet is anything other than convictions before 1960 isn't computerized.
Doing do diligence on a 'lifetime' ought to be fun for some Canadian Firearms Program employee. They could spend a lifetime at it.
