Sit on the Right side of the plane for the best views on flights from Sydney to Montreal. Both sides score equally for the full flight over relatively flat to gently rolling terrain with limited dramatic scenery. However, the right side edges ahead due to the superior landing approach over the St. Lawrence River and Laurentian Mountains, which provide more visual interest during the descent into Montreal than the left side's forest-dominated view.

During takeoff from Sydney (YQY), sit on the Left side for the best views. Sydney, Nova Scotia sits on the Atlantic coast with the Cape Breton Highlands visible inland. Left-side departure offers immediate coastal views of the Sydney waterfront and harbor before climbing over forested terrain. Notable sights include: Sydney Harbor, Cape Breton Highlands, Atlantic coastline, Bras d'Or Lake visible inland.

When landing at Montreal International Dorval (YUL), sit on the Right side for the best views. Montreal's approach from the east brings views of the St. Lawrence River valley, the Laurentian Mountains to the north, and the urban sprawl of the Greater Montreal area. Right-side descent offers better views of the river and surrounding terrain before landing at Dorval. Notable sights include: St. Lawrence River, Laurentian Mountains, Montreal urban area, Île-Perrot and river islands.

The flight from Sydney (YQY) to Montreal International Dorval (YUL) takes 3h 15m.

The flight crosses the Maritime provinces and Quebec interior, passing over the Nova Scotia interior forests, the Gulf of St. Lawrence region, and the Appalachian foothills of Quebec. Notable features include the Cobequid Mountains in central Nova Scotia, the transition from coastal to inland terrain, and the St. Lawrence River valley as the aircraft approaches Montreal. The route generally follows a west-northwest heading over relatively low-elevation, forested terrain with few dramatic peaks or distinctive landmarks visible at cruise altitude.
