At least in the U.S. its pretty straight forward.

Look at http://www.brunton.com plastic baseplate and mirrored compasses. If it is green, its made by Brunton. If its an Eclipse (809x) its made by Brunton. The rest is made by Silva of Sweden.

Not sure if the Brunton-made compasses are made in the U.S. or some Asian country.

No clue about Canada.
