We'll see what my colleague might wish to add to this answer, but my own view is, as long as is necessary. The increase in the covered bond limit has been very helpful in improving the liquidity of banks.
An earlier questioner was talking about the use of government guarantees in order to create mortgage-backed securities that can be used for liquidity. One of the features of the Canadian covered bond system is that the covered bond collateral has to be uninsured, so this is all a private risk. Nonetheless, it's been an efficient way to help increase the ability of banks to borrow against some of their assets, which has been necessary, particularly in the early weeks of the crisis, and may yet come back. We're certainly prepared to leave it in without setting a deadline at this point.
I don't know whether Mr. Gully wants to add something.
