The way I understood the comments was that my research demonstrated that there was an increase in public transit usage as a result of this tax credit, and that's correct. The reason I came to a different conclusion is that the cost of the increase—in other words, the cost-effectiveness of the policy—is poor. The study I did suggested that this tax credit cost between $1,200 and $4,800 for each additional public transit rider, which is very expensive. Similarly, the cost to reduce carbon emissions with this policy was between $1,000 per tonne and $22,000 per tonne. These are really high costs compared to other options we have. It's not that it didn't do anything; it's that it did something in a very expensive way. That's why I reached the conclusions I did.
