You may start submitting the Report Form once you receive confirmation that your application has been reviewed and approved, and birth or adoption has occurred. If your leave start date has past, you should immediately submit for any period in arrears. If your leave start date has yet to arrive, you must wait until that time. The form covers two weeks (the first Monday to the second Sunday; unless you use the special version which can cover up to seventeen weeks) and to simplify the process, it is recommended that you start with the first Monday following your leave start date. This avoids having to prorate your first and final weeks.
