SME: what is a small and medium-sized enterprise?
Everyone uses the acronym, but the thresholds depend on who's counting. Here they are, and why they differ.
An SME, or small and medium-sized enterprise, is a business of limited size, usually defined by its number of employees. Innovation, Science and Economic Development Canada defines SMEs as businesses with 1 to 499 paid employees, while Quebec's language office describes a PME as having fewer than 250 employees.
In short
- ISED Canada: SME = 1 to 499 paid employees; small business = 1 to 99.
- Quebec's OQLF: fewer than 250 employees, management centred on the owner.
- Quebec had 228,622 small employer businesses in December 2024.
- Self-employed people with no staff are left out of these statistics.
How does the federal government define an SME?
ISED's Key Small Business Statistics 2025 classifies businesses by number of paid employees: small businesses have 1 to 99, medium-sized businesses 100 to 499, and large businesses 500 or more. SMEs therefore cover businesses with 1 to 499 paid employees [1].
One detail matters a lot: enterprises without paid employees are generally not included in that publication [1]. A plumber working alone with no staff doesn't show up in those counts.
How does Quebec French define a PME?
Quebec's Grand dictionnaire terminologique defines a petite et moyenne entreprise as a business with fewer than 250 employees, characterized by centralized, personal management around the owner-manager, flexibility, adaptability and innovation, and close ties with its stakeholders [2].
It notes that management is often shared by a team that also shares ownership, and recommends writing the acronym without periods: PME [2]. The definition describes a way of running a company as much as a size.
| Source | Threshold | Basis | Typical use |
|---|---|---|---|
| ISED (Canada) | 1 to 499 paid employees | Employee count | National economic statistics |
| ISED: small business | 1 to 99 paid employees | Employee count | Provincial comparisons |
| OQLF (Quebec) | Fewer than 250 employees | Size and management style | French terminology and writing |
Funding programs often use their own definition; always read the criteria of the program you're applying to.

How much of the workforce do small businesses employ?
The same publication reports that small businesses with 1 to 99 employees accounted for 46.6% of private-sector employees in Canada in 2024, against 17.0% for medium-sized and 36.4% for large businesses. Quebec represented 22.1% of Canadian private-sector employment [1].
For a service company, the takeaway is simple: most of your competitors, suppliers and often your customers are SMEs too.
Which classification mistakes are common?
- Quoting 98% of businesses are small without saying it refers to employer businesses.
- Applying ISED's 500-employee threshold to a program that uses another test, such as revenue.
- Mixing small business (1 to 99) and SME (1 to 499) in the same table.
- Assuming an SME is exempt from Quebec's Law 25, which applies to anyone carrying on an enterprise that holds personal information.
Why do service SMEs have particular needs?
The OQLF definition puts it well: management revolves around the owner-manager. In a six-technician company, the same person answers calls, prepares quotes, runs payroll and watches the numbers. The tools that help are the ones that bring information into one place, like a dashboard built on real data.
It's also why many SMEs choose software as a service over software installed on site: no server to manage and a predictable subscription.
How does Pilotiko serve SMEs?
Pilotiko is a Quebec web application built for service SMEs. It shows a virtual office where each department is a room and each employee or AI agent has a desk. Online booking, assignment based on calendars and workload, internal reports and a hosted website are available today; any action that touches a customer, money or a send waits for a person's approval.
