I just use my UK cards in the UK :P But theres
a growing trend there of people fitting readers onto machines etc .... Best to walk into a branch if possible, and I've seen people do this in say Kenya, quick it is not.

Its worth stating, as hinted to above that it's $10,000 Canadian in whatever form it takes. So that's like $8k USD. Or U$4k and C$5k, or any other combination. When I travelled over with multiple old currencies (maybe 6-7 types) and some less well known options) I again kept a list and made sure I was well under.

But again, if you can explain it... just declare it and don't book a 1h or other short MCT time at your Canadian port of entry! Even if on the same PNR.
