Mr. Chair, we noted in paragraph 3.9 that between the last time we did this audit and the current audit, the Canada Revenue Agency in 2009 began administering the Ontario corporate tax. In 2010 they began collecting harmonized sales tax for British Columbia and Ontario. So between the two audits there certainly was a difference in the base taxes that the Canada Revenue Agency was managing.
On May 2nd, 2013. See this statement in context.
