Canada’s GDP problem is a lesson for the U.S.

By Easton Martin | August 27, 2026

With the United States and Canada now locked in another escalating trade and tariff fight, understanding why the Canadian economy began falling behind the United States is more relevant than ever. The United States imposed 50 percent tariffs on roughly $20 billion of Canadian goods this month after trade negotiations collapsed, while Canada has announced retaliatory tariffs in response.

For years, Canada and the United States appeared to be moving along broadly similar paths when measured by real GDP per capita. That relationship began to change around the middle of the last decade, with the United States eventually pulling substantially ahead.

Immigration and rapid population growth are an important part of the story, but the evidence points to a broader economic problem rather than a single cause.

Canada’s own statistics show that real GDP per capita was essentially flat around 2015 and 2016. Statistics Canada records real GDP per capita at approximately $57,600 in both years using its current chained-dollar series. The economy subsequently struggled to generate strong gains in output per person.

One major problem was weak productivity and investment.

Statistics Canada has identified declining business investment as an important factor behind Canada’s productivity problems. Investment per worker fell sharply following the 2014 and 2015 collapse in energy prices and never fully recovered. Canada also developed a significant productivity gap with the United States during this period.

Population growth created another challenge because GDP per capita is literally economic output divided by population. If a country adds people faster than it expands productive economic activity then total GDP can rise while GDP per person stagnates or falls.

This became particularly significant after Canada dramatically expanded immigration and temporary migration. Population growth accelerated from 0.8 percent in 2015 to 1.5 percent in 2018 and 1.6 percent in 2019. After the pandemic it became dramatically larger, reaching 2.5 percent in 2022 and 3.1 percent in 2023. The Canadian government says international migration accounted for the overwhelming majority of recent population growth.
