Let me break apart the question a bit.
There is a process at the Bank of Canada that deals with mutilated notes, which is separate. If you find notes that are buried and you're not able to determine what denomination they are, they can still be redeemed at the Bank of Canada. Whether they're buried or destroyed, or sometimes destroyed in a fire, we have a service that we provide to Canadians in order to make sure they retain their value.
With respect to legal tender status, we looked globally at what the best practice was internationally. Generally, it's a period of time after the announcement of the removal of legal tender status where in fact you do enact that. It's the first time in Canada, so we're going to be learning as we go along in terms of what the appropriate actions need to be in how we communicate that to Canadians. However, in response to your direct question about whether there are alternatives and whether there is an extended timeline that can be provided, you have to recognize that we have not issued a $1,000 note for 18 years now, since 2000. Understanding that there are still some that are out there, as I said, they will always be redeemed at the Bank of Canada. We have mechanisms in place today where we can accept and give credit and face value for those notes.
