At the Canada Revenue Agency, the evidence shows that duplication is estimated at 56%. This means that 56% of the Canada Revenue Agency's business is carried out by Revenu Québec. According to the IRAI, this leads to savings of $287 million. This means that we have the same service, that citizens provide the same things, but that we save $287 million, like the GST and the QST. Am I making sense?
