Canada is home to an enormous variety of mountain ranges, stretching from the Arctic islands in the far north to the Appalachian foothills of the Atlantic provinces. The western half of the country holds the most dramatic peaks, including Mount Logan in the Yukon at 5,959 meters (19,551 feet), the highest point in Canada and second highest in all of North America. But mountains also define landscapes in Quebec, Labrador, and the eastern seaboard. Here’s a closer look at the major ranges and what makes each one distinctive.
The St. Elias Mountains: Canada’s Tallest Peaks
The St. Elias Mountains in southwestern Yukon contain the highest individual peaks in Canada, and it’s not even close. Mount Logan tops the list at 5,959 meters, followed by Mount Saint Elias at 5,489 meters, a boundary peak shared with Alaska. Mount Lucania (5,260 m), King Peak (5,173 m), and Mount Steele (5,020 m) round out the top five. In fact, all ten of Canada’s highest summits belong to the St. Elias range.
These mountains are geologically young and still rising. Rapid tectonic uplift continues in this region, producing steep, precipitous terrain covered by massive ice fields. The combination of extreme elevation and heavy snowfall supports some of the largest non-polar glaciers in the world. Most of these peaks are remote and rarely climbed compared to the better-known Rockies.
The Canadian Rockies
The Rocky Mountains are the range most people picture when they think of Canadian mountains. They run through western Alberta and eastern British Columbia, forming the spine of the continent and the backdrop to national parks like Banff, Jasper, and Kootenay. Despite their dramatic appearance, the Rockies weren’t simply pushed up into their current shapes. Tectonic forces during the Laramide Orogeny, roughly 55 to 60 million years ago, created a high-elevation upland with relatively gentle relief. The sharp ridges and deep valleys visible today are the product of tens of millions of years of erosion working on rocks of different hardness.
The mountains consist largely of ancient Paleozoic and, in some areas, even older Proterozoic rock. Harder layers held up to weathering and remain as high ridges, while softer rock eroded into valleys. This is why the foothills east of the Rockies look so different: the softer surface rock there can’t maintain steep slopes, so the terrain rolls rather than towers. Glaciers during the ice ages carved the Rockies further, scooping out the U-shaped valleys and turquoise lakes the range is famous for.
The highest peak in the Canadian Rockies is Mount Robson at 3,954 meters, located on the British Columbia side near the Alberta border. While impressive, that’s nearly 2,000 meters shorter than Mount Logan in the St. Elias range.
The Coast Mountains of British Columbia
Running parallel to the Pacific coast for over 1,600 kilometers, the Coast Mountains form a massive wall between the ocean and British Columbia’s interior. Unlike the layered sedimentary folds of the Rockies, these mountains were carved by water and glacier ice from an uplifted mass of granitic rock with more uniform resistance to erosion. The result is broader massifs and wide glaciated valleys rather than the sharp, folded ridgelines typical of the Rockies.
The range includes several distinct sub-regions. The Boundary Ranges sit along the Alaska border in the north, the Kitimat Ranges occupy the central coast, and the Pacific Ranges extend through the southern part of the province. Coastal weather systems dump enormous amounts of precipitation on the western slopes, feeding dense temperate rainforests at lower elevations and extensive ice fields higher up. The eastern side sits in a rain shadow, creating a drier, more transitional climate. Mount Waddington, at 4,019 meters, is the highest peak entirely within British Columbia and stands in the Coast Mountains.
The Columbia Mountains
Tucked between the Rockies and the Coast Mountains in British Columbia’s interior, the Columbia Mountains are often overlooked but contain four significant sub-ranges: the Cariboo, Monashee, Selkirk, and Purcell Mountains. These ranges catch heavy snowfall from moisture-laden Pacific air that rises over the interior plateau, making them a hub for backcountry skiing and home to some of the deepest snowpacks in North America.
The Columbia Mountains are geologically older than the Rockies and built from different rock. They feature metamorphic and igneous formations rather than the sedimentary layers that define the Rocky Mountain front ranges. Dense forests of cedar and hemlock cover their lower slopes, giving way to alpine meadows and glaciers higher up. Mount Sir Sandford, the tallest peak in the group at 3,519 meters, sits in the Selkirk range.
The Appalachians in Eastern Canada
The Appalachian Mountains extend from Alabama all the way to Newfoundland and Labrador, a total distance of about 3,200 kilometers. In Canada, they pass through New Brunswick, Nova Scotia, Prince Edward Island (where they are barely perceptible), Quebec’s Gaspé Peninsula, and Newfoundland. These are among the oldest mountains on Earth, and hundreds of millions of years of erosion have worn them down to modest elevations. Mount Jacques-Cartier in Quebec’s Chic-Choc range tops out at 1,268 meters, making it one of the highest Appalachian peaks in Canada.
The Canadian Appalachians are defined more by rolling highlands, river valleys, and rugged coastline than by towering summits. The landscape supports thick boreal and mixed forests, and the region’s character is shaped as much by the sea as by the mountains themselves. The Long Range Mountains on Newfoundland’s west coast are one of the most striking Appalachian sub-ranges in Canada, rising sharply from the Gulf of St. Lawrence.
The Laurentian Mountains of Quebec
North of Montreal and Quebec City, the Laurentian Mountains stretch about 1,400 kilometers across Quebec. They are one of the oldest mountain ranges on the planet, formed roughly one billion years ago as part of the Canadian Shield. That extreme age means they’ve been ground down significantly. Elevations generally range from 500 to 1,000 meters, with the highest peak, Mont Raoul-Blanchard, reaching 1,166 meters.
What the Laurentians lack in height they make up for in accessibility and cultural significance. The range is the outdoor playground for millions of Quebecers, drawing skiers, hikers, and cottagers year-round. The rounded, heavily forested hills and thousands of lakes reflect the long history of glacial erosion that has shaped the Canadian Shield over hundreds of millions of years.
The Arctic Cordillera
Canada’s most remote mountain range runs along the northeastern fringe of Nunavut and into northern Labrador, spanning Ellesmere Island and Baffin Island. The Arctic Cordillera contains peaks exceeding 2,000 meters, some of the highest in eastern North America. Barbeau Peak on Ellesmere Island reaches 2,616 meters and is the highest point in Nunavut.
This is a landscape of extremes: jagged peaks, deep fjords, and vast ice caps exist under months of polar darkness in winter and continuous daylight in summer. Vegetation is nearly nonexistent at higher elevations, and glaciers flow directly into the Arctic Ocean. Very few people ever see these mountains in person, but they represent one of the most striking and least-explored mountain environments anywhere in the world.
The Torngat Mountains
At the northern tip of Labrador, where the Arctic Cordillera meets the Atlantic coast, the Torngat Mountains rise dramatically from deep fjords. Mount Caubvick (also called Mont D’Iberville on the Quebec side) is the highest peak east of the Rockies in mainland Canada at 1,652 meters. The range is protected as Torngat Mountains National Park and is co-managed with the Inuit of Nunatsiavut.
The Torngats are characterized by polar bears, caribou herds, and some of the most rugged coastal scenery in eastern North America. Glacially carved cirques and knife-edge ridges give these mountains an alpine feel that surprises visitors who associate Atlantic Canada with gentle, rolling terrain.
