I think I'll answer the question by going back again to my experience in New Brunswick, which is a small province when compared to the complexity of the federal government. In New Brunswick, when we tabled a budget that included an amount of total expenses we also tabled main estimates that completely reconciled to the expenses in the budget. There was a direct link on a full accrual basis between the estimates and the budget speech of the minister, and they were all tabled on the same day.
On March 28th, 2012. See this statement in context.
