Just as scylla has said, as a visa exempt foreign national, the chances of any issues are slim. My guess would be that provided you bring your copy of the application package with you and answer any question truthfully, you’ll be fine.
There’s always a small risk, IRCC state that readmission is never guaranteed, but it seems to be the case that far more people are allowed back in without issues, that those who end up being grilled in secondary. Good luck!
