Well we have another mini crisis...my aunt has lost my cousins birth certificate. She is 15 and has only a SIN as ID. We leave on Jan.12. She has a photocopy of it, if this was notorized would that be good enough? I know we have to show them at the border (we are flying out of Buffalo), what about at the airport--what ID is required for check in? Is there something else we could do to get an original in hand before we go?
