Certificate is sent directly to the visa office along with the rest of your case, so you won't see how the actual Certificate looks like. (In my case the documents were sent to Buffalo).
What is mailed to you is a letter and a confirmation form of the provincial nomination. This confirmation form is to be sent along with the original CIC forms... (remember that Alberta asked you to send the copies with your AINP application so you should have the originals)
Additionally you'll have to send birth/marriage certificates, copy of H1b, etc. police certificate, photos, proof of funds and money.
