The divergence stems from geography, history, economy, and culture:
Atlantic Provinces (NS, NB, PEI, NL): Ocean-moderated, shorter winters, longer growing seasons. NWT: Arctic/subarctic, long severe winters, permafrost.
Atlantic: European settlement since 1600s; established institutions. NWT: Late 19th/20th century; resource extraction frontier, indigenous homeland.
Atlantic: Diversified—fisheries, agriculture, forestry, tourism, energy, tech. NWT: Resource-dependent (diamonds, gold, oil/gas), heavy federal transfers.
Atlantic: Multi-ethnic European roots, maritime culture. NWT: Majority Indigenous (Dene, Inuvialuit, Métis), distinct languages, traditions.
These factors created a settled, diversified Atlantic vs. a remote, resource-reliant, Indigenous-majority North.
