Canada's Export Dependence on US Market Due to Size and Proximity

The Gravity Model, a widely accepted equation in economics, provides valuable insights into Canada's export dependence on the US market. According to this model, trade between countries is positively related to their economic sizes relative to the global economy. The large size of the US economy, both absolutely and relatively, contributes significantly to Canada's reliance on the US as a market for its exports.

The Gravity equation also identifies transportation costs, freight costs, and differences in laws and regulations as influencing geographical trade patterns. A shared physical border between Canada and the US is another factor contributing to Canada's disproportionate reliance on the US market.

To achieve greater geographic trade diversification, substantial investments in Canadian rail and port infrastructure may be necessary to reduce transportation costs to non-US markets. Trade agreements with non-US partners and ongoing promotion initiatives by governments and business organizations could help lower non-transportation-related hurdles to increased Canadian exports to non-US markets.

The most promising alternative foreign markets for Canada are those poised to increase their share of world GDP, particularly if they are already relatively large in size globally.
