So that would seem to indicate that this would not prevent his PR from being approved.
Perhaps, but based on the experience of a previous poster that was caught by CIC working under presumed "implied" status of an IEC visa when in fact he was working illegally... the inland app wasn't rejected or cancelled, but was forwarded to another office for special processing. This of course can add months to years in delays while they sort out the issue. So while perhaps not grounds to be rejected, it is grounds for an incredible delay.
It still appears though that very few people are actually caught here working under expired IEC. Most likely due to how the departments that deal with IEC/working holiday programs, SIN data, inland apps, etc... share (or don't share) information with each other.
Same as working with no work status in a job for cash. Illegal, but most people aren't actually caught. However the ones that are pay the price, so no matter if the risk of getting caught is small, you can't recommend people to do it.
