Sit on the Left side of the plane for the best views on flights from London to Toronto. While the right side wins at Heathrow departure, the left side delivers the superior overall experience. The Toronto approach on the left is genuinely world-class — the CN Tower, Lake Ontario, and the islands together make for one of the best urban approaches anywhere. Over the Atlantic and Canada, the left side also faces south toward Greenland's ice sheet and the Gulf of St. Lawrence coastline on the great circle route.

During takeoff from Heathrow (LHR), sit on the Right side for the best views. Heathrow departures heading west on runway 27L/27R give the right side a clear view over central London as the aircraft banks northward. You'll see the Thames snaking through the city, with the dense urban grid of West London and the City visible before the aircraft tracks northwest. Notable sights include: River Thames and its westward bends near Kew and Richmond, Windsor Castle and Windsor Great Park to the southwest, the M25 orbital motorway arc, Wembley Stadium arch visible to the north.

When landing at Lester B Pearson International (YYZ), sit on the Left side for the best views. Pearson typically uses runways 05/23 or 06L/06R. On the common eastward approach to runway 05 or 06L from the west, the left side faces south toward downtown Toronto, Lake Ontario, and the CN Tower. This is one of the most dramatic urban approaches in North America. Notable sights include: CN Tower and downtown Toronto skyline, Lake Ontario stretching to the south horizon, Toronto Islands and Billy Bishop Airport, the curved shoreline of Scarborough to the east.

The flight from Heathrow (LHR) to Lester B Pearson International (YYZ) takes Approximately 8 to 8.5 hours westbound.

The great circle route tracks northwest over Ireland, then across the North Atlantic passing south of Iceland and over southern Greenland's ice cap edge, then across Labrador and Quebec. Visible features include the Irish coastline near Shannon, occasional icebergs and pack ice south of Greenland at lower latitudes, the rugged fjord coastline of Labrador, the St. Lawrence River valley and Gulf, and the flat agricultural patchwork of southern Ontario on descent.
