*IIRC there is no US border control facility in the UK, so she would have been turned away by the airline's check-in system because she had neither a visa waiver nor a visa.
There is at the larger airports, when I moved from the UK to the US I had to go through US immigration in the airport before I got to enter the waiting area for the flight.
The other point you make however (RoFo didn't need an esta as a Canadian visitor) is correct though - I don't think you need a visa waiver if you're Canadian entering the US, do you?
