I don't have a study here with me, if you're asking me to produce a study. We looked at various materials when we were preparing the budget for 2006. I don't have much doubt that if a person can save two months' worth of transit a year—for example, in my community of Whitby, taking the GO train into Toronto—they're happy to do that.
You have to be a monthly user. This tax credit was not designed for casual users of public transit; it was targeted at people who commute. That's why the qualification is there for a monthly pass.
