I don't get forewarnings. However, we can ask for details from the Treasury Board Secretariat as to the amounts that are being frozen or reprofiled. We can, if we want, get into the weeds as to exactly what's being reprofiled.
To the first part of your question on whether that's a good way to measure, I think it is. When central agencies, as we call them—Treasury Board Secretariat—see that this money won't be needed, it's prudent management to ensure that it is frozen to ensure that it doesn't get spent on other purposes and is reprofiled to future years, or if there's a savings target, that the money is frozen to ensure that it doesn't get spent by departments.
