Kathleen Cooper's work has suggested a tax credit and there also are tax credits or different kinds of financial incentives that can be done through loans for renovation. Quebec does have a loan renovation program for which one can apply. They've just added radon to that as well, so if you have up to $3,000 of renovation costs and over, you can apply for radon remediation within that work.
There are different models for doing it, but I do believe that financial incentives are what get people to change. I changed my hot water heater because I got a financial incentive to do it. Otherwise, I don't think I would have done that. If we think about it, if we're offered just a little bit, all of us might take that extra step, plus it shows a leadership role.
