A visual storyboard of Canada’s Arctic sea routes — showing geography, sovereignty, and the real economics of Arctic shipping.
The Northwest Passage is a network of channels weaving through the Canadian Arctic Archipelago, not a single canal.
Typical Atlantic–Pacific sailing distance: 5,000–6,000 km (3,100–3,700 miles), depending on the route chosen.
Bellot Strait — approximately 2 km wide, with strong tidal currents that limit safe transit.
Canada asserts the Passage is internal waters, allowing full legal control over transit, safety, and environmental protection.
Some states argue it could become an international strait if regularly ice-free, granting free passage.
Extremely narrow channels, seasonal ice, and lack of alternative deep-water routes support Canada’s legal position.
| Factor | Economic Impact |
|---|---|
| Distance savings | Up to ~10–15% shorter than Panama for Asia–Europe routes |
| Ice-class ships | Higher construction and operating costs |
| Seasonal access | Usually limited to late summer windows |
| Insurance & risk | High premiums due to ice, remoteness, rescue limits |
| Primary users today | Resource carriers, research vessels, expedition cruises |
Narrow channels + ice variability = control points.
Canada’s claim is reinforced by physical reality, not just legal theory.
Climate change opens opportunity, but risk and cost still dominate decisions.
