AC834 departed at 6pm, so I assume the extra 2 hour period for YYZ was to account for possible exposure even after the infected person left the area. I was at the airport after 6pm, but luckily did not wander down to Gate D24.
What about those passengers that continued on to GVA on that same plane? I assume the infected passenger got off at YUL since the article only mentions the segment to YUL. According to FlightAware, there was approximately 2h15min between arrival and departure for the 2 segments in YUL. I highly doubt they wiped down any surfaces or sanitized the plane during its short layover in YUL before continuing onto GVA... and there was probably less than 2 hrs between deplaning and boarding...
