I just want to address the issue of tax evasion. It is not a simple matter; that's for sure.
As representative of a union that represents most of the auditors Canada Revenue Agency engaged in this work of going after tax avoiders and tax cheats and getting offshore money, I can tell you that very complex systems are needed and very complex interactions between jurisdictions are required. I don't think you can water that down by having provincial versus federal. It's already very difficult to get complete sets of information from countries—even countries we have treaties with.
If you really want to address the problem of tax evasion, then what the money should be spent on is not rebuilding a whole new system in Quebec but rather investing in the areas required federally, like technology and training for people who are up against some of the most complicated technology and some of the most expert tax avoiders in the world.
There is a lot of work that can be done to improve Canada's tax system, but if you want to get back to the issue of simplifying things for Quebeckers, there is a way to do that. It doesn't require a complete overhaul of both the Quebec provincial system and the federal system to do that. That's just likely to create turmoil and a whole bunch of risk about outcomes for our ability to continue to collect taxes.
