hey crjlover
mainly what you have to do is to file a PRM (preferred route message) sent via AFTN to the appropriate OAC (gander for eastbound-shanwick for westbound) you should provvide this info asap, and not later than 1900 utc for the following day time OTS and 1000 utc for the following night time OTS.
addresses and formats for provviding PRMs are pubblished in the canadian and UK AIP'S\NOTAMS.

hope this answers your question
