Pearson Intl, ON (CYYZ) to San Francisco Intl, CA (KSFO). As the aircraft was on a visual approach to Runway 28R at KSFO, ATC cleared ACA759 to land. Approximately 0.6 nautical mile from the runway threshold, the flight crew asked ATC to confirm the landing clearance for Runway 28R because they were seeing lights. ATC responded in the affirmative, and re-cleared ACA759 to land on Runway 28R. The controller was coordinating with another facility when a flight crew member from another airline taxiing on Taxiway C queried ATC as to where ACA759 was going, then stated that ACA759 appeared to be lined up with Taxiway C which parallels Runway 28R. ACA759 had overflown Taxiway C for approximately 0.25 miles when ATC instructed the aircraft to go around. Four aircraft were positioned on Taxiway C at the time of the event. It is estimated that ACA759 overflew the first two aircraft by 100 feet, the third one by 200 feet and the last one by 300 feet. The closest lateral proximity between ACA759 and one of the four aircraft on Taxiway C was 29 feet. The NTSB is investigating.
