the parents don't live in a hotel, they live with extended family, or friends that are already here. And many come from some places that don't need a visa, some are only here 20 days and deliver. It's not that expensive. And heaven forbid that child needs an emergency heart operation right after delivery ( that's why they are here) it could (does) cost us many thousands.
It happens a lot in Toronto, its next to the biggest melting pot and an international airport.
