If (when, rather than if) the USD bites the dust we will be chocking on it also. The US and Canada can open up as many embassies and bid on as many new contracts as they like but it will be China/India/Russia that will be signing on the dotted line. When you go and blow up a country you don't get the contracts to rebuild it also. That is so last century it's funny to think it would ever happen again.
In this case it is, 'Cheer up Canada things could be worse.' (so we cheered up and sure enough things got worse) Which is better, speak up now before you are a refugee or once you are a refugee. (when nobody is listening as like these days)
Any refugee who is let in has a story to tell, one that is worth money after a war crimes trial and guilty verdict. The x-ISIS members would probably have the best stories and they probably sing like a canary if the price is right.
There IS a harder currency that you can hold, instead...
You forgot your wallet.
