If Iceland were to adopt the Canadian dollar

Nick Rowe brings up the topic.

There are plenty of interesting comments there on how this would work. In particular, how would the Icelandic banks secure liquidity if they were to move to a Canadian  dollar standard? It seems to me that local Canadian banks could act as lenders of last resort to the Icelandic banking system.

Alternately, if Icelandic banks were willing to submit to Canadian regulation, then perhaps things could proceed one step further and get admittance to the Canadian Payments Association, Canada's central clearing system. As members they would get Bank of Canada lender of last resort assurance.
