Hon. Percy Mockler: Honourable senators, my question to the Leader of the Government in the Senate is concerning the two billion trees to be planted. In January, the Parliamentary Budget Officer estimated that this program would cost $5.7 billion. Given that Natural Resources Canada, or NRCAN, and the government said very little progress has been made on this program to date, and that you have just had to rework your original plans, is this still projected, as per the government, that it would cost $3.16 billion? Who is right?
