Sit on the Right side of the plane for the best views on flights from Mexico City to Toronto. The right side delivers the most dramatic single moment of the flight — the close view of Popocatépetl and Iztaccíhuatl on departure from Mexico City is genuinely spectacular and unique. The Toronto approach on the left is excellent but the volcanic departure view edges it out overall. Mid-flight over the US interior, neither side has a decisive advantage.

During takeoff from Licenciado Benito Juarez International (MEX), sit on the Right side for the best views. MEX typically departs northeast on runway 05R/05L. A right-side seat faces southeast toward the Sierra Nevada volcanic chain, giving you a direct view of Popocatépetl and Iztaccíhuatl rising above the Valley of Mexico. The left side faces northwest over the urban sprawl of the city with no comparable landmark. Notable sights include: Popocatépetl (active volcano, 17,802 ft), Iztaccíhuatl (dormant volcano, 17,159 ft), Lake Texcoco remnant basin, eastern Mexico City urban grid.

When landing at Lester B Pearson International (YYZ), sit on the Left side for the best views. YYZ typically lands from the west or southwest on runways 05 or 06L/R, meaning the approach track comes in over Lake Ontario from the southwest. A left-side seat faces south toward Lake Ontario and the Toronto downtown skyline including the CN Tower, which is clearly visible during the approach. The right side faces north over suburban sprawl with no comparable feature. Notable sights include: Lake Ontario, Toronto downtown skyline with CN Tower, Toronto Islands, Humber Bay shoreline.

The flight from Licenciado Benito Juarez International (MEX) to Lester B Pearson International (YYZ) takes Approximately 4 hours 30 minutes to 5 hours.

The route tracks northeast over the Mexican plateau, crossing the Sierra Madre Oriental, then over the Gulf Coast lowlands of Tamaulipas and into Texas. Over the US, the flight crosses the Edwards Plateau, then the flat agricultural plains of Oklahoma, Kansas, and Missouri. Crossing the Great Lakes region, Lake Erie and the southern Ontario shoreline become visible before descent into Toronto. The Mississippi River may be visible as a broad meandering ribbon over Missouri or Illinois depending on exact routing.
