I think it would depend on whether or not a deposit had been paid for this camera. If they didn't, then tough beans, presuming the buyer had received several calls to pick it up.
Just spoke to the folks at Millennium Photo, they no longer do E-6, or large formats.
But still cover B&W and C-41 in 35mm and 120/220.
I now get all my chemicals and film from Big Camera. He advertises here on APUG from time to time. Knowledgeable and good pricing. He only carries quality products and delivers promptly. Just contact him. His name is Rob. Don
For you Toronto guys I have been hearing rave reviews about Caribou Film Lab from photographers I know who are sending their film over there. They are doing process and scan for all types of roll film.
I've been tempted to send some film out there myself but it's a long way away and I've been pretty happy with my lab in Vancouver.
There's still Toronto Image Works which does a fine job and covers B&W, C-41, and E-6 and does 4x5.
Just in case, it may be of interest to you that chemicals for C-41 and E6 processes are available on my website.
I also have a small quantity of Rollei color films (C-41, E6 or cross-process).
Have a great day!
Since B&H started offering $9 Purolator ground shipping, I have have stopped buying film in Canada but continue to buy my chemicals locally.
