Yes, you are on the right track. The estimates indicate that we are requesting a writeoff of about $149 million. Those writeoffs did occur over a three-year period, so 2008-09, 2009-10, and 2010-11. The last time Parliament was asked to agree to a writeoff of direct student loans—loans that are provided directly by the Government of Canada—was in 2007-08, so the year just preceding this three-year period.
On November 29th, 2011. See this statement in context.
