I think Kirsten did a good job trying to be diplomatic, and inoffensive, as her job dictates, while also giving a mainly American audience the Canadian perspective on recent events.
I think the most striking question though was the one about whether Trump influenced the Canadian elections and why Canadians 'picked' Mr. Carney.
That's not really something an apolitical representative of Canada should comment on...
It did occur to me that while the interviewer was aware her job was apolitical, he probably has the U.S. system of Presidentially appointed ambassadors (often overtly partisan, with changes following a U.S. election) in his head.
In Canada, while those appointments do ultimately come before cabinet, they are more commonly career diplomatic appointments, or at least more qualified, and typically these don't align with Canadian elections, but when someone's term comes up (Ambassador's) or when they resign/retire etc.
