Depending on your school they may offer daycare facilities to you- if cost is an issue (and I understand it can be) this may be your best option. There may be subsidies are grants available but you would need to do your research on that one, as I'm not sure.

Wait lists usually apply to licensed daycare facilities, but if you know the postal code to the city you will be living in you can look up what private homes are offering daycare and make a decision based on that- usually if they are being advertised here it means they have a spot to fill. As artsand crafts said, 300 seems -really- low, I would be quite surprised if you found anything less then 500 a month, but I guess it depends where you live. Here in ottawa typical monthly costs are 800-1000 per month.

Most daycare centers or homes will post examples of their typical schedules and menus.
