The Seven Wonders of the World Affair (1) - S4-E15
Revealing mistake: Illya flies a helicopter to the Himalayas in search of Solo, and at the same time, Kingsley's men are loading an unconscious Solo into another copter. Not only do the two helicopters look suspiciously similar - they have the exact same registration number: N73959. (00:44:40 - 00:46:30)
Answer: He must have ridden in an Eaton's store elevator while he was in Canada at some point. For some reason, this elevator reminds him of it. The show's original concept had Solo being a Canadian, so this may be a minor nod to that fact.
