Vacation time earned for a vacation entitlement year (or stub period) must be taken within 10 months after completing that year (or stub period). You have the right to schedule vacation + are required to ensure the vacation time is scheduled and taken before the end of that 10-month period.
Employees may waive some or all of their earned vacation TIME (if the employer agrees + the Ontario Director of Employment Standards approves) but not their vacation PAY.
