Unfortunately you're clueless in your retort, I sought clarification from DriveTest myself before going down there, and they said because I had a CA/DL, the license information would already be in their system and to just come down. They had issues with their system at the time I physically went down which was the only reason they didn't do the exchange, and because they couldn't put a time limit on the problem to be solved, they simply suggested I get the record of origin.
Also, it doesn't help when most people don't understand what a record of origin is, since it's under the guise of an abstract, and abstract tends to mean a simple driving record, which the record of origin is not. Not even the CA DMV people I talked to until I called back after sending it in knew the difference. I happened to get lucky and find one lady who knew what it was I wanted -- I had plainly stated on a piece of paper I had sent in it was to fulfill a request from DriveTest in Ontario for an "abstract of origin for their license exchange program".
Thankfully some of us already had a clue, unlike some who came up with crummy presumptions.
