We have some estimates that we produced in the annual tax expenditure report. We have figures on the reduced inclusion rate for capital gains, for example, on donations of publicly listed securities. The estimate is that the reduced inclusion rate provided a tax benefit of $34 million in 2011. For donations of cultural property, we estimate the figure to be in the $6 million range.
We have estimates that go back to 2006, when the measure was introduced. We'd be happy to provide those figures to the committee. They are available in the 2011 version of our tax expenditure report.
