Size and shape

How many businesses there are and how small they are. Fragmentation is the first thing an entrant — or anyone selling software into this industry — needs to know, and it is one of the few things that is actually measured.

Largest four provinces by establishment count. Establishments with employees only — sole operators with no payroll are not in this table, so in trades and personal services the true number of businesses is higher.

Measured, not forecast: the share of US establishments opening in one year that were still active later. It counts good operators and bad ones together, which is exactly why it is the honest answer to “what are the odds”. It is for the whole sector rather than this market, and the ten-year figure comes from an older cohort because no younger one has reached ten years.

How businesses here compete

The structural profile of subsector 221, which every industry beneath it inherits. This is analyst judgment from how the subsector is organised — not research into this industry, and not a measurement.

regional competitionhigh capitalUNVERIFIEDinherited from 221 Utilities

Regulated monopoly or near it. The openings are at the edge — independent generation, water and wastewater operations, services sold to utilities.

Who sets the price: Regulators, through rate cases; merchant generators take the pool price.
The software it runs on: Billing and customer information systems, metering, outage and asset management — long procurement cycles, few vendors.

Water, Sewage & Other SystemsOne thing must be true

binding constraint: distribution

Water is the one utility Canadians have decided not to sell. Statistics Canada's inventory of core public infrastructure counts 3,325 water treatment facilities in the country in 2022, of which 2,776 — 84% — belong to municipalities, plus 1,648 wastewater treatment plants in public hands. Against that, this whole industry group has 374 businesses with employees, and 161 of them have one to four. So the asset is not for sale, and the entrant's only product is a service sold into municipal procurement: twelve to twenty-four month cycles, RFP-gated, scored on references an entrant does not have, and awarded by a council that answers to ratepayers rather than to a return. The American comparison shows what the alternative model costs to build. American Water Works, the largest listed water utility in the United States, grew in 2025 by closing 18 separate acquisitions of regulated systems for US$83M in total, adding about 20,900 customers between them — an average of roughly 1,160 customers a system, bought one council vote at a time, on top of a US$5,121M revenue base built over 140 years. Even that pace is now being abandoned for scale: in October 2025 American Water agreed an all-stock merger with Essential Utilities. The business here is aggregation at utility cost of capital, and it is a thirty-year project, not an entry.

Software serving this industry

The vertical software markets filed along the same branch — who sells to these businesses and who they would have to displace — and then the generic categories every business buys whatever it does.

No vertical software market has been recorded along this branch. What the subsector typically runs on: Billing and customer information systems, metering, outage and asset management — long procurement cycles, few vendors.

And what every business buys · 25 generic categories

Sold to every industry rather than this one, so they are filed against the software industry's own code. The same few vendors recur across most of them.

Who works here

The occupations employed in Utilities, most concentrated in it first. The share is measured against the whole sector, not this industry — the published cross-tabulation stops there.

These jobs are mostly done here. An operator in this industry is competing for them against others in the same industry, not against the whole economy.
