That's a great question.
In our advocacy work, we are often asked that question by elected officials. Last year we partnered with the Conference Board of Canada to answer two questions: What's the cost of making the DTC refundable, and what's the cost of making EI sickness benefits more flexible? It's about a billion-dollar investment, but the modelling that the Conference Board did shows an obvious return.
Of course, with MS and other diseases, when MS takes you out of the workforce, the disability tax credit.... I'm not the accountant in the room, but if you don't have enough income, it's about as valuable as Monopoly money. We absolutely need to make that refundable.
