I think it will make a more even playing field.
I know from talking to members of Parliament who have spoken to child care providers in their respective ridings that they have been told their day cares are closing their infant rooms because there is that opportunity to take extended leave in the parental portion. What's happening is if an adoptive or an intended parent can claim the 15 weeks less, they're going to have to go back to work earlier, but there may not be space for them in an infant room because they would be needed in an infant area.
