The Canadian dollar has been worth more than a US dollar most every day this year. Our buck's been trading within a fairly tight range in 2011. Today, was the first time it's been worth over $1.02 though.
I cannot imagine the difficulties involved in international trade due to currency fluctuations. Since we've been in Canada, the dollar here has been a cheap at $US0.64 and as high as $1.12. Yet, I never see immediate changes in the prices of either imports or exports. On something such as a home, these differences must add up to equivalent of thousands and thousands of dollars. So, what about trade measured in the billions? My mind boggles.
