Sit on the Left side of the plane for the best views on flights from Hong Kong to Toronto. Left side wins at both ends of the flight. Over Hong Kong you get the harbor, bridges, and Lantau topography on departure; over Toronto you get the CN Tower skyline and Lake Ontario on arrival. The polar routing over Russia and Canada's north offers limited differentiation between sides at cruise altitude.

During takeoff from Hong Kong International (HKG), sit on the Left side for the best views. HKIA's runways point roughly east-west on Lantau Island. Departing westbound over the Pearl River Delta, the left (south) side gives you the best view of Lantau Island's mountainous interior, Cheung Chau island, and the broader Pearl River estuary. Eastbound departures on the left side look directly over Tsing Ma Bridge and the Tsuen Wan/Kowloon urban mass. Notable sights include: Tsing Ma Bridge, Lantau Peak (Tai Tung Shan), Pearl River Delta estuary, Kowloon Peninsula urban grid.

When landing at Lester B Pearson International (YYZ), sit on the Left side for the best views. Pearson's primary arrival runways (06L/06R) bring aircraft in from the west-southwest over Lake Ontario and the Toronto lakeshore. The left side on this approach tracks directly over the western Toronto waterfront, giving clear views of the downtown skyline including the CN Tower, the lake, and the city grid spreading north. Right side sees suburban Mississauga sprawl with less visual interest. Notable sights include: CN Tower and downtown Toronto skyline, Lake Ontario shoreline, Toronto Islands, Humber Bay.

The flight from Hong Kong International (HKG) to Lester B Pearson International (YYZ) takes Approximately 15 to 16 hours.

The route tracks north from Hong Kong over southeastern China, crosses into Siberia over the Gobi Desert fringe, then follows a polar great-circle arc over the vast Siberian taiga and Lena River basin, crosses the Bering Strait region or northern Pacific depending on routing, transits Alaska or Yukon, then descends over the Canadian Shield through Ontario. At cruise altitude the dominant features are the endless boreal forest and river systems of Siberia, the Alaska Range as a distant white ridge if routing goes that way, and the Canadian Shield's lake-studded granite terrain on descent.
