Sit on the Left side of the plane for the best views on flights from Montreal to Sydney. While takeoff offers good river and mountain views on the right, the landing approach on the left provides more dramatic and distinctive scenery—the Bras d'Or Lakes and Cape Breton's rugged Atlantic coastline are visually striking and geographically unique. The landing experience outweighs the takeoff advantage.

During takeoff from Montreal International Dorval (YUL), sit on the Right side for the best views. Right-side seats offer views of the St. Lawrence River valley and the Laurentian Mountains as the aircraft climbs northeastward out of Montreal. The river's distinctive meanders and the forested ridge line of the Laurentians are clearly visible during the initial climb phase. Notable sights include: St. Lawrence River, Laurentian Mountains, Montreal urban sprawl, Île-Perrot.

When landing at Sydney (YQY), sit on the Left side for the best views. Left-side seats provide excellent views of the Atlantic coastline and Cape Breton Island's rugged terrain during the descent into Sydney. The Bras d'Or Lakes and the island's distinctive geography are prominent on approach from the west. Notable sights include: Bras d'Or Lakes, Cape Breton Island, Atlantic Ocean coastline, Sydney Harbour.

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

The flight path crosses the Maritime provinces, passing over the Appalachian highlands of New Brunswick and Nova Scotia. Notable features include the Bay of Fundy (visible on the left/north side during the eastern portion of the flight), the forested interior of Nova Scotia, and numerous river valleys carved through the Appalachian terrain. The landscape transitions from the St. Lawrence lowlands to increasingly rugged, glacially-sculpted topography as the aircraft moves eastward toward the Atlantic coast.
