The people in the article don't seem as happy about it as you.
It's very very bad for people trying to make money. It's very very good for people who are spending money.
The Canadian economy has been overheating for a while so this is to be expected. The reality is however this has a lot more to do with the sagging US economy than a strong Canadian dollar. The Canadian dollar is treading water vs. the Euro and other currencies. It is really only making big gains against the US, just as everyone else is.
This is a mixed news for Canadians but it is really bad news for the US. Canada is BY FAR the US's largest trading partner at about $550 Billion/year in trade. You now don't get a 30% bonus as you did a few years ago. 30% on $550B is $165B - that's serious coin. It would be great if you could shift your buying elsewhere but the US dollar is down against almost all other currencies and we are too close. The other alternative is to make things cheaper in the US but that's not happening and we have a natural resource advantage right now.
