Canada is one of the world’s major Arctic nations, with its northern regions covering vast areas of the circumpolar North. The Canadian Arctic includes the three northern territories, Yukon, Northwest Territories, and Nunavut, while Arctic and sub-Arctic regions also extend into northern parts of provinces such as Manitoba, Ontario, Quebec, and Newfoundland and Labrador.

Stretching nearly 8,000 kilometres from east to west, the Canadian Arctic encompasses immense tundra landscapes, mountain ranges, glaciers, and the Canadian Arctic Archipelago, the world’s largest group of Arctic islands. The region has long been associated with Arctic exploration and the historic search for the Northwest Passage, linking the Atlantic and Pacific Oceans through northern waterways.

Geography and Population

Canada’s Arctic accounts for more than 40 percent of the country’s total landmass, yet it remains sparsely populated. Approximately 150,000 people live in northern Canada, many in small and remote communities.

Indigenous peoples form a large proportion of the Arctic population, particularly Inuit communities in Nunavut and Inuit Nunangat, as well as First Nations and Métis peoples across the North. Indigenous cultures, languages, and traditional knowledge continue to shape life throughout the Canadian Arctic.

The Arctic is deeply connected to Canada’s national identity and increasingly important to the country’s economic, environmental, and geopolitical interests.

Climate Change and Environmental Challenges

Canada has been at the forefront of international discussions on Arctic climate change. Northern communities are already experiencing rapid environmental transformation, including melting sea ice, thawing permafrost, coastal erosion, changing wildlife patterns, and increased risks to infrastructure and transportation.

These changes create both challenges and opportunities. While climate change is opening access to Arctic shipping routes and natural resources, it also threatens ecosystems, traditional livelihoods, food security, and cultural heritage.

Canada has participated actively in international environmental agreements and Arctic scientific cooperation, emphasizing the importance of sustainable development and environmental protection in the North.

Arctic Governance and Indigenous Partnerships

Canadian Arctic policy has evolved significantly in recent decades. Today, governance in the North increasingly emphasizes cooperation with Indigenous peoples and territorial governments.

Land claim agreements and self-government arrangements have transformed political structures across northern Canada. The creation of Nunavut in 1999 marked a historic milestone in Inuit self-governance and remains one of the largest Indigenous land claim settlements in the world.

Canada’s Arctic policies generally focus on several key priorities:

• Protecting Arctic sovereignty
• Supporting sustainable economic development
• Advancing reconciliation with Indigenous peoples
• Strengthening northern infrastructure and security
• Preserving Arctic ecosystems and biodiversity

Indigenous knowledge and community participation are now considered essential components of Arctic policymaking and research.

The Canadian Arctic Archipelago

The Canadian Arctic Archipelago consists of thousands of islands north of the mainland, including some of the world’s largest Arctic islands such as Baffin Island, Ellesmere Island, and Victoria Island.

The archipelago covers approximately 1.4 million square kilometres and forms a central part of Canada’s Arctic sovereignty claims. Canada exercises internationally recognized sovereignty over these islands, which are administered primarily through Nunavut and the Northwest Territories.

The region contains important ecosystems, glaciers, polar deserts, and marine habitats, while also playing a growing role in Arctic shipping, scientific research, and national security.

The Northwest Passage

One of the most internationally discussed issues in the Canadian Arctic is the Northwest Passage, a network of sea routes running through the Arctic Archipelago between the Atlantic and Pacific Oceans.

Canada considers the waters of the Northwest Passage to be part of its historic internal waters. However, some countries, including the United States and several maritime nations, view the passage as an international strait where freedom of navigation applies.

The debate has gained increased attention as climate change reduces summer sea ice, making Arctic navigation more accessible for longer periods of the year. Although commercial shipping through the passage remains limited and difficult due to ice conditions and infrastructure challenges, interest in Arctic shipping continues to grow.

Canada has emphasized the need for environmental protection, safety regulations, Indigenous consultation, and responsible navigation throughout Arctic waters.

Maritime Boundaries and Arctic Sovereignty

Canada’s Arctic maritime claims are governed largely under the United Nations Convention on the Law of the Sea (UNCLOS), which defines territorial seas, exclusive economic zones (EEZs), and continental shelf rights.

One longstanding maritime issue involved the Beaufort Sea boundary between Canada and the United States. The area is believed to contain significant hydrocarbon resources, and both countries historically used different legal principles to define the maritime boundary. Despite differing positions, Canada and the United States have continued to cooperate closely in Arctic security and environmental management.

Another territorial issue involved Hans Island (Tartupaluk), located between Canada’s Ellesmere Island and Greenland (click to read more about it). For decades, both Canada and Denmark claimed sovereignty over the small uninhabited island. In 2022, the two countries reached a historic agreement to divide the island peacefully, creating the first land border between Canada and Europe.

The agreement has often been highlighted as an example of successful Arctic diplomacy and international cooperation.

Canada’s Role in the Arctic Today

Canada remains a leading Arctic nation and an active participant in Arctic governance, research, and diplomacy. The country continues to invest in northern infrastructure, scientific monitoring, Arctic security, and partnerships with Indigenous communities.

As global interest in the Arctic grows due to climate change, shipping, natural resources, and geopolitical competition, Canada’s northern regions are becoming increasingly important both nationally and internationally.

At the same time, many Arctic residents and Indigenous organizations emphasize that the future of the Canadian Arctic must prioritize environmental stewardship, cultural preservation, community well-being, and sustainable development for future generations.
