That's why in our report we suggest that there must be an alternative measure to give a tax credit to transit users that would be more efficient. You need all kinds of measures to encourage the use of transit by Canadians, especially if you want to reach our goal in GES reduction, so it's very important.
As a matter of fact, as we said, it's an increase of 15% for most of the users who claim the tax credit. But what we usually see when there's an increase in fares.... The elasticity of fares is about 25% or 30%, so it could be more than what's estimated by Professor Rivers, but we don't know. You have to test it, of course, to see the results, as they did in Quebec with the program. But with the program they had in Quebec, everybody thought that 50% elasticity on better headway between buses was too much, but they got to their goal, so really it was a success.
You have to try it.
