I called CIC call centre to know about my case processing centre. I used this number 18882422100. After that I spoke to an agent and got to know where my visa office is. Hope this helps.
Hi,
The best way is to send email to your your case processing centre. I followed this step to add my new born.
I Sent email to cpc Ottawa and got a request letter in profile the next day. So first thing is to contact your CPC directly first.
