most of the pro colour films, black & white films and sheet Ektacolor paper from Rochester, black & white paper from Canada and Ektachrome from France. . OzJohn
Right arround that time Kodak's Canadian Plant was in a bit of an upset also. It had been built to mostly provide the Canadian Market behind what was at the time a rather large Tariff wall. So Popular items were made there and smaller items were packed and final assembled there.
It was hard to tell what was imported, for example I used to use Plus-x bulk film, which came in a Canadian Kodak Box, but was edge printed KODAK S'AFETY FILM, while individual rolls of Plus-X were edge printed KODAK SA'FETY FILM. (the Kodak Limited stuff was edge printed KODAK SAF'ETY FILM) WHo knows where it was actually coated.
In the grey market stuff Eaton's sold, it all said made in England, except the High Speed Ektachrome which said it was made by Eastman Kodak in USA and Packaged by Kodak Limited in England.
When NAFTA came in The Canadian Plant with it's lower volumes was adrift, and the business news said that it in different years had a mandate to produce (1) Colour paper, (2) _ALL_ colour Motion Picture Negative film, and I think finally all B&W paper. I was still playing with Movie negative for stills at that time using short end film and sure enough I did see more of the SA'FETY film markings. But they disappeared when the KeyKode system came out, and I suspect that also meant Movie Neg went back to Rochester.
The LAST package of Kodak B&W paper I ever bought said it was Made for Eastman Kodak by Kodak Canada. I suspect that Nafta also resulted in a lot of US market stuff suddenly being labelled in Both English and French. (and possibly Spanish)
