Canada

So, typical conservatives.

Let them get very serious about separation. and its consequences. Only when they face it will they realize what they'll have. Or not have. I can tell you one thing - once they have their own currency, it will appreciate. It'll make oil production costs more expensive, make their oil and gas less profitable. Further, their currency becomes directly pegged to the oil price, with little to no stability which makes doing business and trade-dependent economy like theirs and ours more difficult and costly. They will ask to continue to use Canadian dollar and we should absolutely refuse it - they want the benefits without the costs.

Equalization payments are there for economic imbalances. Look at EU. Once Germany joined EU and uses Euro, it is like a currency depreciation making their goods more cost effective in the world market. Thus Germany enjoys a huge trade surplus. It's not a coincidence Germany has had huge trade surpluses since they went to a common currency. This surplus would shrink if they went back to their own currency, as the Mark will appreciate due to the trade surplus vs other currencies making their goods less competitive in global market.
