In January 2007 the Euro was at $1.52 CAN. Today it's at $1.39. Not an insignificant increase but hardly comparable to our dollar's performance vis-a-vis the USD, especially if you look at the last five years instead of the last 10 months. Exactly 5 years ago, the USD was worth $1.56 CAN. Today it's at 96 cents. Compare that to Euro, which was worth $1.53 CAN in October 2002 and is worth $1.39 today.
Yes but why are you comparing the Canadian dollar to the Euro?
Lets look at a comparison of the Canadian dollar to the Chinese renminbi (yuan). Since you were comparing the last 5 years I'll list the exchange rate for the last 5 years also.
04 Jan 2002 5.18 Chinese renminbis 5.1813 (0.1930)
28 Oct 2002 5.31 Chinese renminbis 5.3050 (0.1885)
27 Oct 2003 6.32 Chinese renminbis 6.3171 (0.1583)
27 Oct 2004 6.75 Chinese renminbis 6.7522 (0.1481)
27 Oct 2005 6.90 Chinese renminbis 6.9013 (0.1449)
27 Oct 2006 7.05 Chinese renminbis 7.0522 (0.1418)
26 Oct 2007 7.78 Chinese renminbis 7.7821 (0.1285)
In 2002 one Canadian Dollar bought 5.18 renminbis. Today one Canadian dollar buys 7.79 renminbis. We can buy 1.502 more of their currency today.
Now lets look at the Canadian dollar compared to the US dollar.
25 Jan 2002 0.62 US dollars (noon) 0.6219 (1.6079)
28 Oct 2002 0.64 US dollars (noon) 0.6408 (1.5605)
27 Oct 2003 0.76 US dollars (noon) 0.7632 (1.3102)
27 Oct 2004 0.82 US dollars (noon) 0.8159 (1.2257)
27 Oct 2005 0.85 US dollars (noon) 0.8549 (1.1697)
27 Oct 2006 0.89 US dollars (noon) 0.8938 (1.1188)
26 Oct 2007 1.04 US dollars (noon) 1.0396 (0.9619)
So compared to January of 2002 we can buy 1.74 more US dollars.
As I have said before China has basically pegged their currency to the US dollar. They have made small concessions (in their eyes) and have slowly increasing the value of their currency. They will not allow it to float and obtain its real value because they do not want to upset their balance of trade (imbalance actually) with the USA.
The Canadian dollar has progressively increased much more in value compared to the US and Chinese currency compared to other currencies in the world. Our dollar has increased in real value (compared to the rest of the world) and at the same time the US dollar has dropped. Because the Chinese have tied themselves to the US dollar we see a much larger gain in purchasing power buying from the USA or China today compared to other countries.
Shopping in the USA looks real attractive not only because our dollar is so much higher than the American dollar but because the Chinese products we go down there to buy are being sold to the USA for the same in US dollars as before the slide in their dollar.
