I would say these two things.
It's a fact: workers are doing the same job twice and that creates duplication of work, which the bill wants to eliminate. However, this may threaten jobs. By the same token, I recognize the importance of providing jobs in the regions.
First, negotiations must be undertaken with the Quebec government. Many of these jobs may well move to Revenu Québec, and they would be subject to the terms and conditions of the relevant collective agreements. This is a possibility that should be considered, if it satisfies the parties involved in the negotiations and if it suits the employees.
Given that the public service is understaffed and centralized in Ottawa, doesn't the government have the ability, the opportunity and the desire to say that these are important jobs for the regions? Agency employees could be assigned to other duties or offered work in another department. This would send a strong signal.
The excellent research paper provided by the Library of Parliament on this bill notes that 11% of Canada Revenue Agency jobs are in Quebec, even though the province accounts for a quarter of the population. So we see that we are not getting our fair share. The same is true for the public service as a whole.
In my opinion, if the government does more decentralization, it will be possible to maintain the number of jobs. This subject is particularly close to my heart.
