Growth in gross domestic product (GDP), the total value of all goods and services produced in the economy annually, is one of the most frequently cited indicators of Canada’s economic performance. Journalists, politicians and analysts often compare various measures of Canada’s total GDP growth to other countries, or to Canada’s past performance, to assess the health of the economy and living standards. However, this statistic is misleading as a measure of living standards when population growth rates vary greatly across countries or over time.

Federal Finance Minister Chrystia Freeland, for example, recently boasted that Canada had experienced the “strongest economic growth in the G7” in 2022. Although the Trudeau government often uses international comparisons on aggregate GDP growth as evidence of economic success, it’s not the first to do so. In 2015, then-prime minister Stephen Harper said Canada’s GDP growth was “head and shoulders above all our G7 partners over the long term.”

Unfortunately, such statements do more to obscure public understanding of Canada’s economic performance than enlighten it. In reality, aggregate GDP growth statistics are not driven by productivity improvements and do not reflect rising living standards. Instead, they’re primarily the result of differences in population and labour force growth. In other words, they aren’t primarily the result of Canadians becoming better at producing goods and services (i.e. productivity) and thus generating more income for their families. Instead, they primarily reflect the fact that there are simply more people working, which increases the total amount of goods and services produced but doesn’t necessarily translate into increased living standards.

Let’s look at the numbers. Canada’s annual average GDP growth (with no adjustment for population) from 2000 to 2023 was the second-highest in the G7 at 1.8 per cent, just behind the United States at 1.9 per cent. That sounds good, until you make a simple adjustment for population changes by comparing GDP per person. Then a completely different story emerges.

Canada’s inflation-adjusted per-person annual economic growth rate (0.7 per cent) is meaningfully worse than the G7 average (1.0 per cent) over this same period. The gap with the U.S. (1.2 per cent) is even larger. Only Italy performed worse than Canada.

Why the inversion of results from good to bad? Because Canada has had by far the fastest population growth rate in the G7, growing at an annualized rate of 1.1 per cent—more than twice the annual population growth rate of the G7 as a whole at 0.5 per cent. In aggregate, Canada’s population increased by 29.8 per cent during this time period compared to just 11.5 per cent in the entire G7.

Clearly, aggregate GDP growth is a poor tool for international comparisons. It’s also not a good way to assess changes in Canada’s performance over time because Canada’s rate of population growth has not been constant. Starting in 2016, sharply higher rates of immigration have led to a pronounced increase in population growth. This increase has effectively partially obscured historically weak economic growth per person over the same period.

Specifically, from 2015 to 2023, under the Trudeau government, inflation-adjusted per-person economic growth averaged just 0.3 per cent. For historical perspective, per-person economic growth was 0.8 per cent annually under Brian Mulroney, 2.4 per cent under Jean Chrétien and 2.0 per cent under Paul Martin.

Due to Canada’s sharp increase in population growth in recent years, aggregate GDP growth is a misleading indicator for comparing economic growth performance across countries or time periods. Canada is not leading the G7, or doing well in historical terms, when it comes to economic growth measures that make simple adjustments for our rapidly growing population. In reality, we’ve become a growth laggard and our living standards have largely stagnated for the better part of a decade.
