I understand. I would like to come back to the question of volatility, because business is telling us it's very difficult to predict what the dollar's value will be when the time comes to sign contracts. I asked your predecessor, when the dollar was worth 85¢, at what point it becomes more costly to manage volatility, when you have an independent Canadian currency.
However, I would rather ask you to tell me what elements of volatility require special consideration to ensure there is no negative impact on the economy.
