I e-mailed LVO (Ottawa) about new born. Two weeks later, they responded asking for birth certificate, so I scanned and e-mailed it.
Do it as soon as you get birth certificate. I did it through E-mail which is faster and safe.
Sorry for not getting back to you earlier. I don't follow this thread very often.
I had a similar situation. I just e-mailed LVO with Birth certificate, and they were fine with it.
Hope it helps.
