I agree - to a degree, Randy. I’m just saying that I haven’t seen anything definitive that would confirm manufacture in Canada. The information I have about them just packaging ammunition is simply word of mouth and circumstantial and it would be silly to rely on just that.
Remington clearly wanted access to the Canadian market (just as C-I-L wanted access to the US market and set up the Plattsburgh NY operation in 1965 - roughly the same period).
Sending all the components up to Canada to be loaded in Canada would be less efficient than sending the loaded ammunition up there to be packaged. Given the driver for doing this was access to the Canadian market either could be possible. I do not know what trade restrictions were in place in that period that would have forced them to load and/or package in Canada. Canadians wouldn’t have been too bothered with “Made in the USA” on boxes of ammunition, so I suspect it was trade restrictions they were trying to get around rather than strictly a marketing ploy.
I very much doubt that C-I-L would have supplied them with components or loaded rounds. C-I-L was struggling to make their ammunition business viable at that time and wouldn’t have sold a competitor components unless it was stipulated that they not be retailed in Canada.
There’s a couple of avenues for Ron to pursue:-
Check the Remington annual reports to shareholders and their annual financial reports (not always the same document) for the 1972-1979 period. See if they mention moving LOADING equipment back to the Remington plant in the US. This would have cost them and there should be an entry in the financial reports.
Check with the Remington Society of America - see if they have any reports from Remington Canada employees in their archives. If they exist they might mention what actually went on in Toronto and Cambridge.
Trying to find out if the premises they used were registered as a “powder magazine” (thus indicating that had powder for loading) would be very difficult though there might be a way.
