Thank you, Chair.
Thank you to all of our witnesses for being here today.
I want to start my questioning with Professor Boadway, but I invite others to jump in.
Sir, I think you've talked in some of your research about the federal and provincial tax systems becoming less progressive through changes that have benefited mostly high-income earners, such as reduced marginal income tax rates for those earning the highest incomes, and through the introduction of federal non-refundable tax credits, which you've talked about, and through the reductions of capital gains taxation.
I want to ask you to talk a little bit more, because on your wish list this morning you talked a bit it about the desire to make all tax credits refundable. I'd like you to talk a little bit more about that specific topic, and I invite others to do so as well. If you could, comment on any fiscal impacts such a change would have.
