I charge families for their holidays unless it is an extended absence of more than 3 weeks (teachers over the summer for example), they pay for all Stat/civic holidays and I've added a couple others in there like Easter Monday, Christmas Eve and New Year's Eve as paid days too but closed. They pay for all their children's sick days and I have allotted myself 10 paid sick/personal/bereavement days.

As for EI...I pay into it. Your accountant will be able to figure out what the amount you owe for the year is based on your income.
