Hi ROCANG, I agree with giogenre.
Also, notarise all birth certificates, education certificates, previous experience certificates,...etc,..of your & your family members included in your application.
It is better to notarise so that it will give a positive impact for evaluation at CIC & VO.

I did not include the birth certificates because in my country we can get a copy from our National Statistics (census) Office which is already notarized by them (not by a separate notary lawyer). So I'm considering it as an original. Maybe it's a case to case basis and country by country case.
But for Employment certificate, I believe it should be original (from your employer) as indicated in the Document Checklist form and no need to be notarized.
