The Bishops got together and wrote the letter mentioned a while ago. In Manitoba and Ontario I believe it was implamented as of November 1, 2005. In the Eparchy of Edmonton (all of Alberta) the hope is to implament it universally starting January 1, 2006 (if he can get everything written up by then). Several parishes, including mine, have been filioque-less for a while. I am not sure when the other 2 eparchies (Saskatoon & New Westminster) will do so (perhaps they already have).
The reason the Patriarch has not declaired this for the whole Church is not
insufficient preparation of the laity or something like that
but it has something to do with dealing with other church like movements that they are dealing with in Ukraine, and not giving them ammunition. Patriarch has however given his blessing for those Bishops/Metropolia's outside Ukraine to restore the creed.
