Hello Everyone,
I confirmed with one of my friend who was 2011 applicant and in Canada now.They also submitted the matriculation certificate as the proof for DOB.In India matriculation is accepted as DOB for all govt organizations.He didn't face any issue.Also as per Govt. Of India rule: People born before 1989 can submit matriculation or school leaving certificate as a proof for birth certificate as there was no widely accepted concept of birth certificates in India.Even this is true when you apply for new passport application now als

nly people born after 1989 in India require compulsory birth certificate for passport etc.
So I believe for Indian applicants birth certificate is not necessary and CIC would be aware of that as they have processed lot of Indian applicants.
I have also sent only my matriculation and school leaving certificate as proof of date of birth.
One more thing in India when they issue birth certificate in hospitals there is no name for the child.Only parents name,weight and Gender is mentioned.So this will not be accepted by CIC in my opinion.This is because unlike west where people know well in advance there child gender and keep a name for that.In India sex determination is crime.
As a second opinion I confirmed with my lawyer as well and they said birth certificate not require only matriculation or school leaving certificate will work.
Hope this clarifies all curiosity regarding birth certificates.But who knows in what mood CIC officer will be???
