Basement Daycare in Toronto

Hello!

I am interested in opening up my own daycare in my basement. We are currently renovating a legal basement so I have a few questions:

1) I already have two exits in the basement One that leads directly to my backyard and one to go upstairs to the main floor.. Also there are 3 existing Windows. What is the size required for the windows?

2) What is the ceiling height required?

3) is there a layout of a basement daycare in Toronto they someone can share with me?
Is there any additional information I should know about?

Try looking at whichever certifying body is in charge
and go from there.
