Yes Hebe, I have:
No gold back up for Canadian dollar as a matter of political and financial policy.
Fault lies with Canadian politicians who are backing US policy on this matter.
Why no gold backing?
Because gold backing means readly exchanging paper for gold and gold is in short supply.
US is not doing so because they are deeply in debt and all the gold in the world would not save that. In debt due to off sourcing production to the orient but not enough cash to pay for that.
So they print more dollars and thus become indebted.

Similar situation was in the 30s (Depression) and 70s ( Vietnam war debt).

That US dollar is a 'safe haven' is false propaganda to delay the inevitable, a serious devaluation of US dollar. To that end, precious metals being the truest of real money & true safe havens, are being manupulated in price so that investors do not move in hordes from paper to the metals.

The fallacy with Canada is that it decided to ride on US dollar.
