Are Any Canadian Provinces or Territories Entirely Within the Arctic?

No—But Large Parts Are

No Canadian province or territory lies entirely within the Arctic Circle (66°34′N).

Territorial Breakdown

• Yukon: ~60% north of Arctic Circle (Old Crow, Herschel Island).
• Northwest Territories: ~70% north (Inuvik, Tuktoyaktuk, Paulatuk).
• Nunavut: ~95% north (capital Iqaluit at 63.7°N is just south; most communities above).

Provincial Norths

• Quebec: Nunavik region (north of 55th parallel) is subarctic/arctic.
• Newfoundland & Labrador: Labrador's coast north of 60°N.
• Manitoba, Ontario, Saskatchewan, Alberta, BC: Northern fringes touch subarctic but not true Arctic.

Why It Matters

"Arctic" is a climatic/latitudinal zone, not a political one. Canada's Arctic policy applies to all three territories and northern provincial regions, but no jurisdiction is 100% Arctic.
