It's amusing to read an apologia on behalf of the CIC/IRCC bureaucrats who, after all, have only had two years of knowing that this Bill was an election promise and was in the pipeline and that they ought to be getting ready for its effects. McCallum wouldn't have led the Department so lackadaisically, nor have been so beholden to his senior bureaucrats' fumblings and laziness. The CIC bureaucrats who I had to deal with during my PR application stage 3yrs ago are a prime exemplar of Parkinson's Law: work expands to fill the time made available by the management for its completion.
