Calculates an expected paystub using the CRA rules stored for the selected year — nothing is submitted anywhere.
Vacation days are converted to dollars using a calculated daily rate (based on standard hours above, or a standard 2080 hrs/year assumption if left blank).
Holiday pay = (regular wages earned in the 4 work weeks before the work week with the holiday + vacation pay payable for those 4 weeks) ÷ 20, per holiday. Pull the two dollar figures from your own payroll history for accuracy — they can't be reliably auto-derived from arbitrary pay periods.
