Just wait until people in North York or Scarborough find out that it's going to cost them $4-$6 to get downtown instead of $2.90 (or less if one currently has a Metropass).
That's why you start with a scheme that sets the fare at the same level as now for most people's commutes. Once you split the fare, growing one component over another becomes easier.
Think about it. Would councillors really vote against lower fares for users inside their boroughs just because the lower proportion of downtown commuters might eventually pay a little more?
