Is there a by law for opening a daycare in the basement of a house? Specifically in east York Toronto. If so how do I find that out?

Related what other legal items do I need to cross off the list?
Insurance for the daycare/walkways - would be liability?
Will the home need any other types of insurance?

Have you incorporated your business so the business gets sewed not you?

I want to make sure everything is legal befor moving forward.

Thanks
