Qualifying offer of arranged employment
(2) A qualifying offer of employment is one of the following:
(a) an arranged employment as defined in subsection 82(1) of the Regulations, if
(iii) the foreign national holds a valid work permit issued under the circumstances
described in paragraph 204(a) or (c) or section 205 of the Regulations, the offer is made by an employer who is specified on the work permit and the foreign national works for that employer and has accumulated at least one year of full-time work experience, or the equivalent in part-time work, over a continuous period of work for that employer;
I would suggest looking for those paragraphs to see if IEC falls into arranged employment.
Edit: Did the homework for you: http://www.cic.gc.ca/english/resources/tools/temp/work/opinion/codes.asp - Section 205 - Code C21
