What is your profession? there is no any specific place to find one job or AEO. Placement agencies porbably best place for start, but He should not miss local classification like,new papers,local advertising etc, He can help to submit your resume etc,but for interview with employer directly, you need to contact too. If your friend succeed to find a Job which is ready to offer for you, then they need to submit that offer to HRSDC for approval. This process may take little longer around 4-6 weeks depends, if HRSDC approve that job offer,then it would be ready to submit into embassy. Write in google HRSDC and you will find their offical webpage, they have all information for Employer and Employee too, that is best place for all type of informations. Good luck
