Easter Monday is a federal holiday meaning military, federal government, banks, etc. have it off. It is not a provincial holiday. So a lot depends on what you have in your contract.

I have it in the contract with the idea that after the winter if we decided to go visit family we would need the long weekend to do it. Also when my kids were younger they were heavily involved in sunday school pageants, kids choir etc for easter at church so it was always a busy time and the day of rest after was nice. If I have families where neither parent gets the day off I have given care for additional fee but that is up to me.
