Every year, industry data surfaces the same pattern: certain categories of small business consistently outperform others on profit margin and owner earnings, regardless of economic cycle. A recent BizBuySell report, drawing on five years of financial data from businesses actually bought and sold in the U.S. market, confirmed the trend again — vending machine operators, software companies, insurance agencies, and accounting practices topped the list for profit margin, while truck stops, banking and lending businesses, and heavy construction companies topped the list for absolute owner earnings.
The specific numbers are American. But the underlying logic — what makes a business profitable to own, as distinct from profitable to start — applies directly to the Canadian market. And for Canadian buyers, the timing could not be more relevant. Canada is entering what CFIB (the Canadian Federation of Independent Business) has called a “succession tsunami”: roughly three-quarters of the country’s 1.2 million small business owners plan to exit within the next decade, a transfer of more than $2 trillion in business assets — and the large majority have no formal succession plan in place. That combination — highly profitable, well-established businesses whose owners are aging out, with weak succession planning — is exactly the environment where a well-advised buyer can acquire a strong cash-flowing business at a fair price, rather than build one from zero.
This article translates the profitability data into a framework Canadian buyers and investors can actually use.

Margin tells you how efficiently a business turns revenue into cash. Absolute owner earnings tell you how much cash there actually is. The right acquisition sits where a healthy margin meets a revenue base large enough to matter. Source: BizBuySell, U.S. business sales 2021–2025.
What "profitable" means when you're buying, not starting
Before ranking anything, it’s worth being precise about the metric. When brokers list a business for sale, they report discretionary earnings (sometimes called seller’s discretionary earnings, or SDE) — not net income. Discretionary earnings add back the owner’s salary and personal expenses run through the business, because that reflects the total pre-tax economic benefit a new owner-operator would receive. This is the right number to use when comparing acquisition targets, because it tells you what the business can actually put in your pocket, not just what it reports to shareholders.
Two numbers matter, and they answer different questions:
Profit margin (owner earnings as a percentage of revenue) tells you how efficiently a business converts revenue into cash for the owner. High-margin businesses are generally simpler to run, less capital intensive, and more forgiving of a revenue downturn.
Absolute owner earnings (owner earnings in dollar terms) tells you how much money the business actually generates, regardless of margin. A trucking company at a 15% margin on $3 million in revenue puts more cash in your pocket than a software reseller at 40% margin on $200,000 in revenue.
Buyers who only chase the first number end up owning a lot of very small, high-margin businesses (a single vending route, a one-person bookkeeping practice) that don’t generate meaningful income in absolute terms. Buyers who only chase the second number end up owning capital-intensive, thin-margin operations (trucking, construction) that are vulnerable to cost shocks. The right acquisition, for most buyers, sits where healthy margin meets a revenue base large enough to matter.
The three traits of a genuinely profitable business
- Consistent, recurring demand. Businesses that provide something customers need repeatedly and predictably — pest control, accounting, insurance renewals, HVAC servicing — consistently outperform businesses selling discretionary or “nice-to-have” products. This is true in every market, and it’s arguably more pronounced in Canada, where a smaller population base and more seasonal consumer spending punish businesses built on discretionary purchases.
- Scalability. A business that can add revenue without adding proportional cost (software, digital products, some professional services) will always show a structurally higher margin than one where every additional dollar of sales requires a proportional amount of new labour or inventory. This is why software and app companies show up near the top of every profitability study, in every country.
- Capital intensity as a moat. Counterintuitively, businesses that require significant capital to operate — manufacturing, heavy construction, trucking fleets, energy services — often generate the largest absolute owner earnings, precisely because the capital requirement keeps competitors out. Fewer people can afford to enter the industry, so the ones who do face less price competition. This is a very different kind of profitability than the “low overhead” logic behind vending machines or bookkeeping, but it’s just as real, and it tends to produce larger, more durable businesses.

Sector categories that translate strongly to the Canadian market
Layering the U.S. data against Canadian conditions — an aging owner cohort, a smaller and more geographically dispersed population, higher trade exposure, colder-climate infrastructure needs, and a regulatory environment with its own quirks (supply management, provincial licensing, bilingual service requirements in parts of the country) — a few categories stand out as particularly well-suited to Canadian buyers right now:
Essential trades and home services (HVAC, plumbing, electrical, pest control). Canada’s climate makes heating, cooling, and building-envelope maintenance non-discretionary in a way milder climates don’t. These businesses combine the “consistent demand” trait with typically low capital requirements and strong recurring/contract revenue (maintenance agreements, seasonal service calls). They are also heavily represented among aging owner-operators approaching retirement — a direct match with the succession wave data above.
Accounting, bookkeeping, and tax practices. With T1/T2 filing deadlines, GST/HST compliance, and payroll obligations creating built-in recurring demand, these businesses combine high margins with genuine scalability once a firm moves past a certain size. A large share of small Canadian accounting practices are run by sole practitioners nearing retirement age, which is creating real acquisition opportunity in this space.
Insurance brokerages. Renewal-based revenue, regulatory barriers to entry (provincial licensing), and low ongoing capital needs make this one of the more defensible acquisition categories — and, as in the U.S. data, one of the highest-margin.
Waste management, commercial cleaning, and recycling. Contract-based, recurring, and increasingly benefiting from municipal and provincial diversion targets across Canada, this category tends to be underestimated by buyers focused on more “exciting” sectors.
Trucking, logistics, and specialized transportation. Canada’s geography — vast distances, cross-border trade with the U.S., and a national economy dependent on moving goods — makes this a structurally larger opportunity here than in many other countries. It requires more capital and carries thinner margins, but the absolute earnings potential (as the U.S. data confirms) can be substantial, and the capital barrier limits competition.
Construction-adjacent and building trades businesses (electrical/mechanical contracting, concrete, specialty manufacturing). Canada’s ongoing housing supply push across most major provinces is sustaining demand for these categories well beyond a typical cycle, and many of the owner-operators in this space are part of the same aging cohort driving the broader succession wave.
Franchise resales in essential-service categories (fitness, restoration, cleaning) deserve a specific mention: buying an existing, operating franchise location — rather than opening a new one — sidesteps the startup loss period entirely and lets a buyer acquire established cash flow, trained staff, and local reputation from day one.
Categories where Canadian buyers should apply extra caution
The Canadian opportunity in context
For a buyer with capital and the discipline to evaluate discretionary earnings properly (rather than top-line revenue), this is arguably a stronger environment to acquire a business than to start one: an existing customer base, trained staff, and a proven track record replace years of startup risk. The businesses worth pursuing are the ones that combine recurring demand, defensible margins, and — increasingly in Canada — an owner who is ready to talk about retirement.
