I’ve never tried this myself, but 3-in-1 is a naptha-based oil mixture. I wonder if a valve oil for brass instruments would work. It’s usually thin, is petroleum based, and often has anti-corrosive compounds.
Another option could be common mineral oil.
And a final thought, if your tools are in a box, camphor tablets are supposed to be able to protect tools by interacting with the oxygen and depositing a protective layer as it sublimates.
I don’t know which of these are specifically Canadian, but you should be able to find non-American options.
