Alhamdolillah, I got my Visa and COPR after successfully adding a newborn baby.
This is what I did to add a newborn baby:
I arranged all the following documents:
1- Birth Certificate
2- Visa Photo
3-Passport
4-Upfront Medical of baby
5-Paid fee of 150CAD (in advance)
6-Update IMM0008 form
7-Update 5406E (Principle Applicant)
8- Updte 5406 E (Spouse)
I raised CSE that I want to add a newborn baby but after two days of CSE, I got my PPR that clearly states that if change in family composition then do write an email immediately to London Visa office. So, I did and in that email, I attached all the above documents. After 22 days of my email, I got reply from london visa office with Medical Request form 1017E for my newborn baby. I requested my clinic to upload upfront medical of my daughter which i did earlier with the IME no. provided by CIC on form 1017E. Doctor tried to access IME no. provided but it gives the error message. So doctor told me to report this back to CIC that prvided IME no. is not working . So, once again I wrote an email to London Visa office. Explaining them the error message CIC panel docotor getting in emedical system and about my earlier email in which I provided upfront medical as well. After two days, I got another PPR. This Sunday, I submitted my passports through VFS and yesterday, I collected my passports with COPR and Visa.
My advice for all those who are in same situation. Please arrange all the above documents and write an email to your visa office with all the documents. Hopefully, things will go smoothly.
Thanks
