As advised already ,send a mail to them immediately to notify them or raise a CSE to Accra.
On your part ,arrange for the commencement of getting passport document for your newborn......maybe Monday morning since today seems to be holiday .Get it done because Accra will surely ask for it.
Also,get her birth certificate ready also......not the hospital....I'm sure you know what is acceptable.
Get her six passports photographs ready also.
Be in the mood to raise 150CAD /$140 draft also for the processing fees because it's needed compulsorily too.
There are forms for you to update also notably the generic form,additional family information form but you will be told the form to fill .I'm sure your previous POF is sufficient so you may not need to worry.
If it's not ,you may be asked again.
Just send the mail and do your preparations on your part.
Cheers.
