Professional services are the fast-growing employment sector of the past four decades in Canada.Cole Burston/The Globe and Mail
The evolution of employment across sectors offers a clear window into the forces shaping an economy. Economist Arnold Harberger once noted that growth doesn’t unfold uniformly, like dough rising slowly and evenly in the oven, but rather in bursts, like mushrooms springing up unpredictably from the forest floor.
With that perspective, this analysis looks at Canada’s job distribution by sector in 1985, 2005 and 2025 to reveal which sectors have flourished or faded over the past four decades and whether those shifts align with the nation’s economic future.
What we see is that a few sectors dominate the employment narrative – wholesale and retail trade, health care, professional services, manufacturing and even agriculture, which stands out for its remarkable long-term evolution.
Wholesale and retail trade has been Canada’s largest employer in the 21st century, though its share of jobs has fallen from 16.36 per cent in 1985 to 14.24 per cent in 2025. Yet this dominance may soon wane as automation and artificial intelligence increasingly take over retail, sales and customer service roles.
Health care and social assistance rank second and continue to expand rapidly. Driven by an aging population and rising demand for services, they are poised to overtake retail as Canada’s largest employer. Over time, the system has absorbed broader responsibilities, particularly in home care, a trend some people fear may prove unsustainable.
Next comes professional services, the fastest-growing sector of the past four decades – a clear sign of Canada’s shift toward a knowledge-based economy. Demand for skills in computer programming, marketing, consulting and design has driven rapid expansion, but that momentum may soon slow as generative AI takes on many entry-level analytical and creative tasks, reshaping the future of professional work.
Manufacturing has undergone one of the most dramatic transformations. Canada’s largest employer in 1985, it now represents just 8.79 per cent of total jobs, reflecting the country’s shift from goods production to services.
Yet as automation accelerates and global demand for robotics grows, manufacturing could regain strategic importance. Revitalizing this sector may be crucial for Canada’s competitiveness in a technology-driven global economy.
Agriculture tells a story of transformation driven by rising productivity. In the early 20th century, it employed about one-third of the work force; by 2025, just 1.1 per cent.
Mechanization, better fertilizers and new technologies allow fewer people to produce as much, or more, food than ever. Yet the decline also reflects broader shifts, from urban migration to farm consolidation, and the economy’s move toward services.
Overall, the data reveal a steady decline in manufacturing and a persistent rise in service-oriented industries. Yet, as Nobel economics laureate Peter Howitt wrote in The Globe a decade ago, “The technological innovations that drive growth arise sporadically.” We may be on the brink of one of those transformative leaps.
As automation accelerates and robots perform more human tasks, global competition to design and build them will intensify. For Canada, the next wave of prosperity may depend on rebuilding a manufacturing base capable of driving, not merely consuming, technological innovation.
