Well, Mr. Chair, I believe the Department of Finance would have all the numbers in terms of taxes to be recovered respectively, as a result of these changes, of plugging the loopholes, which I believe is an important part of preserving the integrity and fairness of the entire tax system. The government has been very diligent over time in addressing those kinds of concerns.
I think there are some measures in Bill C-4 that are anticipatory. The Department of Finance has picked up signals, either through the Canada Revenue Agency and its relationship with them, or on their own, that certain things might be on the verge of taking off in terms of fiscal effects. Others are simply things that have been in effect, like the leveraged life insurance schemes. Those have been used for many years and I'm sure the cost of that has been significant over the last number of years.
