Sit on the Left side of the plane for the best views on flights from Keflavik to Toronto. Left side wins at both ends of the flight. During the transatlantic crossing the views are largely open ocean, but the left side also offers the best chance of spotting southern Greenland's ice cap edge if the route tracks far enough north, which many KEF-YYZ routings do. Combined with the superior takeoff and landing views, left is the clear choice.

During takeoff from Keflavik Nas (KEF), sit on the Left side for the best views. Keflavik typically departs eastward on runway 10, so the left (north) side gives you a view back over the Reykjanes Peninsula's lava fields and the Atlantic coastline. You can see the geothermal steam plumes near the Blue Lagoon and the rugged volcanic terrain stretching toward Reykjavik. Notable sights include: Reykjanes lava fields, Blue Lagoon geothermal area (steam visible), Faxaflói Bay coastline, Mount Esja across the bay near Reykjavik.

When landing at Lester B Pearson International (YYZ), sit on the Left side for the best views. Pearson typically lands westbound on runway 23 or 24L/24R, meaning the aircraft approaches from the east over the city. The left (south) side gives a clear view of downtown Toronto's skyline including the CN Tower, Lake Ontario's northern shore, and the city grid spreading west. The right side faces north toward suburban sprawl with fewer distinctive features. Notable sights include: CN Tower and downtown Toronto skyline, Lake Ontario shoreline, Toronto Islands, Humber Bay.

The flight from Keflavik Nas (KEF) to Lester B Pearson International (YYZ) takes Approximately 6 hours 30 minutes to 7 hours.

The route typically tracks southwest over the North Atlantic, often passing south of Greenland's Cape Farewell or occasionally close enough to see the Greenland ice sheet edge and fjords on the left side. The Labrador Sea crossing follows, then the coast of Labrador and Quebec, with the St. Lawrence River valley and potentially Lake Ontario visible on descent into Toronto.
