So sorry this is happening to you. In my opinion this certainly sounds excessive! Especially the expectation to be paid for & take days off on US and Canadian stat holidays? That's not right at all. We live in Canada and this should apply to Canadian stats only. Going forward in a new contract I would definitely look for specific vacation time periods (eg. 2 weeks paid vacation, anything over that unpaid). As well as perhaps being very clear about Stats. I live in a border town (I'm assuming you must as well?) and sometimes that gets confusing with parents working of both sides of the border.
