If you are covered under the Employment Act, you will be entitled to 12 weeks of maternity leave. The first 8 weeks of maternity leave will be employer-paid if at the time of confinement, you have fewer than two living children (unless they were born during the same confinement).
Beyond the first 8 weeks, maternity payment from the employer is voluntary and the employer is not entitled to claim any reimbursement from the government.
