Hi Friends,
I just found an authentic answer on CIC website.


What do you mean by surname?

Your surname is your family name. It is sometimes called your “last name.” If your name is spelled differently on your official documents, please write your name as shown in your passport. When filling out applications, type your surname as it appears on your passport, travel or identity document or any letters you got from the visa office or case processing centre where you sent your application (even if the name is misspelled). Do not use initials.


If you do not have a surname on your passport, travel or identity document, enter all your given name(s) in the surname field, write “not applicable” or “N/A” in the given name field.

Hi, I have applied to IQAS for assessment for immigration purpose.
I have a general query about personal information. My Given name xxyy is mentioned on passport and educational documents, no surname is there.
When i registered on IQAS portal, the first name and middle name is optional and last name is mandatory. So i wrote "xxyy" in last name option because it was mandatory to fill up . After that i uploaded all information regarding mailing addresses and educational details. But at the payment time, I got the order form where first and last name are mandatory; the option of first name shows empty(editing is freezed there) and last name is automatically filled as "xxyy", kindly suggest.
 
I am also facing same issue while filling express entry profile as I don't have last name. Registration was successful. But while entering details for Given name and Last name as per mentioned above both are required fields, So name is repeating twice.
 
Hi, it means if I have first and last name on passport, but don't have last name on college documents then I can use last name as in my passport or - in last name ?

The reference link states this

If you’re applying to sponsor your family, you can’t validate Schedule A (eIMM 5669) with the given name field empty. If you need to leave it blank for the above reason, you can print it without validating it, and include a letter with your application explaining why you had to do this.
 
For express entry profiles - both given name and last name fields are marked as mandatory
However, it'd allow you to submit the given name as blank.

At least that's what I was able to do. If it doesn't allow the first time, try transmitting and then editing the family info again.
I hope this helps :)
