You seem to think that they owned their house in Toronto outright, which is rare for a young family, especially in such expensive area. Also, median detached house price in Toronto is just over a million, so if they got a couple of million, they had above average house as well, so it's still not clear how are they affording all of that. But, I don't think that's the point of the article, maybe they are trust fund babies, who cares.
