I don't think so. I think in our brief we mentioned Canadian “parents”. That could be a two-parent family or a one-parent family.
It's absolutely crucial for early learning and child care for a one-parent family. I can speak to that personally, that without that kind of care I have no idea how I would have managed to support my family.
It was just that we lumped it all together as “parents”, be it two-parent families or single-parent families.
