Thank you very much.
Mr. Alexander, one of the charts that the parliamentary budget officer provided last Friday in talking about taxes gave some updates on how much tax income the government plans on collecting in the next five years, until the end of 2021. It says it's about $5.7 billion in extra taxes, and it all seems to be back-loaded in the final three years.
The question I have is this, and maybe Mr. Ball from the CPA Canada can help me. If we're talking about a review of our tax system, having just commissioned this Canada Transportation Act review, which took 18 months and is still in study, realistically from beginning to end how long does it take, from the call for a process to study this system to an end result whereby you see increases in taxation coming in because of efficiency? Isn't that a generational thing?
