The answer will depend on what provinace you are in.
In Ontario - home daycares where never mandated to close. you could have stayed open this whole time, which means you can reopen when you are comfortable doing so.
Currently in Ontario there is a temporary no-payment order in place. This means if a client keeps their child home due to covid-19 they don't have to pay. it is illgal for you to ask them to pay. It is also illgal for you to terminate care due to their lack of payment while keeping their child home.
Currently the no-payment order is set to be revoked on June 9th, however it can be extended again.
UPDATE: The no-payment order was revoked on June 12th. Daycares can not charge as per their contracts.
