Sit on the Left side of the plane for the best views on flights from Toronto to London. Left side delivers the best views at both ends of the flight — the Toronto skyline on departure and the Thames and London on approach. Over the Atlantic the difference is minimal, but the left side also faces south toward Greenland's ice sheet and Labrador coast during the northern routing.

During takeoff from City Centre (YTZ), sit on the Left side for the best views. Billy Bishop (YTZ) sits on the Toronto Islands, so takeoff on runway 08 (eastbound) puts the left side facing north toward the downtown Toronto skyline and Lake Ontario's north shore. You get a direct broadside view of the CN Tower, Rogers Centre, and the dense Financial District towers as the aircraft climbs out over the lake. Notable sights include: CN Tower and downtown Toronto skyline, Toronto Islands and inner harbour, Lake Ontario stretching south, Gardiner Expressway and waterfront.

When landing at Heathrow (LHR), sit on the Left side for the best views. Heathrow's dominant runway 27L/27R approach comes in from the east heading west, so the left side faces south over central London. On final approach at 2,000–4,000 feet you get a clear view of the Thames, the City of London, Canary Wharf, and on clear days the full sweep of the river bends through central London. Notable sights include: River Thames and its central London bends, Canary Wharf tower cluster, The City of London and Shard, Windsor Castle visible to the southwest on very clear days.

The flight from City Centre (YTZ) to Heathrow (LHR) takes Approximately 7 hours 30 minutes to 8 hours.

The route tracks northeast over Lake Ontario, then over the St. Lawrence River and Quebec, before crossing the Gulf of St. Lawrence and Newfoundland's rocky coastline near St. John's. It then crosses the North Atlantic, passing south of Greenland's ice cap visible on the left horizon at cruise altitude. The route clips the southern tip of Iceland's influence zone before descending over Ireland's west coast, crossing the Irish Sea, and entering UK airspace over Wales or the Midlands before the Thames Valley approach into Heathrow.
