OK, took awhile for the coin to drop as I was wondering about what exchange rates had to do with shipping. I meant you are lucky as it takes about $1.50 CAD/AUD to buy a EURO and the Kiwis have to pay about $1.60 NZD for a EURO. Not all dollars are equal.
The shipping to Canada is likely the same or close as for the US as it all comes out of France and has little to with our postal services.
