Have a look at the following link:
http://www.cic.gc.ca/english/immigrate/skilled/assess/Education.aspAlso even though u have 16 yr education looking at the self assessment if you select
Obtained a university degree of two years or more at the bachelor's level and completed at least 14 years of full-time or full-time equivalent studies
you score 20 points. This might be a little orthodox compared to your masters and no. of yrs of education.If your total pts are 67 that is wat matters.
Coming to your certifications, the certifications do not help in immigration. A person with similar educational background like yours without a certification might also be eligible based on the points,type of education and NOC code. The certifications will surely help while you apply for jobs there.
