Again, if there is a need for further information or clarification, the individual would speak to a visa officer to be able to clarify.
Perhaps just to take a step back, the process with what we would call a triage centre here in Canada would be that it would be staffed 24/7, and if there were issues like this that came up, there would be a human intervention in Ottawa. In regard to the same name, perhaps that intervention could clarify, through conversations with our security partners, whether or not this was the individual in question or if it was a bit of an identity issue, in which case Ottawa—the triage centre—could authorize the eTA without the individual needing to speak to an officer. If there was still confusion after the triage centre had engaged with screening partners, then there would be a request for an interview with a Canadian visa officer.
