Construction employs over a million Canadians in the private sector, and almost nine in ten of them work for a small or medium-sized business rather than a large one.
Headline figure

Total private-sector employment in Canadian construction in 2024 — 1,179.2 thousand people, per Table 6 of Innovation, Science and Economic Development Canada’s Key Small Business Statistics 2025 (page last modified 23 April 2026), which draws on Statistics Canada Table 14-10-0215-01.
What the data says
The distribution matters more than the total. In most large industries employment concentrates in big firms; in construction it does the opposite. Seven in ten construction employees work for a business with fewer than 100 people, and only about one in eight works for a large business.
| Business size | Employment (thousands) | Share |
|---|---|---|
| Small (1–99 employees) | 830.7 | 70.4% |
| Medium (100–499 employees) | 200.2 | 17.0% |
| Small and medium combined | 1,030.9 | 87.4% |
| Large (500+ employees) | 148.4 | 12.6% |
| Total | 1,179.2 | 100% |

The combined small-and-medium row is the sum of the two rows above it and matches ISED’s own stated 87.4% SME share. Private-sector employees only.
The Labour Force Survey does not publish a construction headcount in its release text, but it names construction whenever the industry moves enough to matter. In the July 2026 release, published 7 August 2026, Statistics Canada reported that “employment rose in July in finance, insurance, real estate, rental and leasing (+18,000; +1.2%), professional, scientific and technical services (+17,000; +0.8%) and construction (+16,000; +1.0%)”. The companion chart data for the same release puts the construction change at +15.7 thousand, drawn from Table 14-10-0355-01 — the small difference is rounding between the headline figure and the unrounded chart series, not a discrepancy.
Two months earlier the gain was larger: the May 2026 release, published 5 June 2026 recorded that “Employment increased in several industries, most notably in construction (+27,000; +1.7%)”. That release added the important qualifier that “employment in May was little changed on a year-over-year basis in construction” — monthly gains that do not compound into annual growth.
There is no single official “X people work in Canadian construction” number in Statistics Canada’s analytical releases, which is part of why the figures circulating online vary so widely. The 1,179.2 thousand above is a specific, defined measure: private-sector employees in 2024. It excludes the self-employed, who are a larger share of construction than of almost any other industry. If a number is quoted to you without that definition attached, it is not comparable to this one.
Because 87.4% of construction employment sits inside small and medium businesses, most of the industry’s administrative load falls on firms with no dedicated back office. The same company running payroll for a crew is also chasing the progress claim, tracking the holdback and filing the safety paperwork. That is the structural fact behind how small Canadian construction firms really are and the industry’s opening and closure record.
