What should my resume or CV look like for the IEC application?
Keep it simple, thorough and in bullet points.
It doesn't need to be fancy. Plenty of people with limited work experience apply and simply list their information in bullet points.
Be thorough: Try to include everything you can. Missing something small, like a short temp job from several years ago, isn't going to be a dealbreaker.
Format: IRCC provides a suggested format you can follow. Contact us if you'd like a copy.
Work History section: You'll also fill in a Work History section in the application. It overlaps a lot with your CV, so expect some repetition.
